• ropemacs USAGE tutorial

  - by Headcrab

  There are many sites with instructions on installing ropemacs, but so far I couldn't find any with instructions on how to use it after it's already installed. I have it installed, or at least it seems so, Emacs has "Rope" menu in it's top menu bar. Now what? So far I could use only "Show documentation" (C-c d by default). An attempt to use code assist (which is auto-complete, I presume?) only causes Emacs to ask about "Rope project root folder" (what's that?) in the minibuffer and then showing nothing. So, once ropemacs is installed, what are the steps to see it in action on some simple python scripts? Something like "if you have this script in your emacs and put the blinking square here and press this, it does that" would be an answer. (I've been thinking if I should ask this or not for some time, because nobody else seem to have the same problem, so I thought asking this question will make me look somewhat retarded. But, after all, it's usually better to ask it and and look like a retard than not to ask it and do like a retard...)

• General Drools Question

  - by El Guapo

  For the last few months my company has been using a product from a company called Informatica (previously AgentLogic) called RulePoint. This product has proven itself very easy to use with a well-developed and easy-to-use SDK for customization. The way we use the product for CEP is fairly trivial, we have 2 sources which we monitor for our rule data, the first being a JMS Queue, the second being a Jabber IM account. The product runs on any java-based application server (WebLogic, Tomcat, etc) and runs just about flawlessly. Last week my boss says, "Hey, I've heard that we may be able to do the same thing we are doing with RulePoint with an open-source product called Drools. Check it out and let me know what you think." I've heard of people using Drools for flow-based operations (validation, etc), however, I've never heard of anyone using their CEP product (Fusion) in practice. So, being the diligent worker, I have undertaken this task. I've downloaded all the files (version 5.0) and accompanying documentation and have started to read. I've read through just about all the docs and run most of the examples, but I still don't really see HOW drools works for CEP. While there are examples for using Data (or Facts, I guess) from JMS, I don't see how this thing stays "running", continuously monitoring a queue until the application is actually stopped. RulePoint pretty must just sits and listens, however, Drools seems to not. I could probably write a full-blown command-line application for our needs, however, I was hoping to leverage some of the benefits of using a application server provides. I guess I'm looking for some good tutorials or an example of how someone is using Drools and CEP in production. Thanks in advanced for any information, advice you may be able to provide.

• Nhibernate: distinct results in second level Collection

  - by Miguel Marques

  I have an object model like this: class EntityA { ... IList<EntityB> BList; ... } class EntityB { ... IList<EntityC> CList; } I have to fetch all the colelctions (Blist in EntityA and CList in EntityB), because if they all will be needed to make some operations, if i don't eager load them i will have the select n+1 problem. So the query was this: select a from EntityA a left join fetch a.BList b left join fetch b.CList c The fist problem i faced with this query, was the return of duplicates from the DB, i had EntityA duplicates, because of the left join fetch with BList. A quick read through the hibernate documentation and there were some solutions, first i tried the distinct keyword that supposelly wouldn't replicate the SQL distinct keyword except in some cases, maybe this was one of those cases because i had a SQL error saying that i cannot select distict text columns (column [Observations] in EntityA table). So i used one of the other solutions: query.SetResultTransformer(new DistinctRootEntityResultTransformer()); This worked fine. But the result of the operations were still not passing the tests. I checked further and i found out that now there were duplicates of EntityB, because of the left join fetch with CList. The question is, how can i use the distinct in a second level collection? I searched and i only find solutions for the root entity's direct child collection, but never for the second level child collections... Thank you for your time

• YUI DataTable - Howto have just one paginator?

  - by Rollo Tomazzi

  Hello, I'm using the YUI DataTable in a Grails 1.1 project using the Grails UI plugin 1.0.2 (YUI being 2.6.1). By default, the DataTable displays 2 paginators: one above and another one below the table. Looking up the YUI API documentation, I could see that I can pass an array of YUI containers as a config parameter but - what are the names of these containers? I've tried loooking at the HTML of the page using Firebug. The ID of the divs containing the paginators are: yui-dt0-paginator0 (above) and yui-dt0-paginator1 (below). If I use them to configure the containers for the navigator, then the navigator is just not displayed at all. Here's the relevant extract of the GSP page containing the Datatable element. <div class="body"> <h1>This is the List of Control Accounts</h1> <g:if test="${flash.message}"> <div class="message">${flash.message}</div> </g:if> <div class="yui-skin-sam"> <gui:dataTable controller="controlAccount" action="enhancedListDataTableJSON" columnDefs="[ [key:'id', label:'ID'], [key:'col1', label:'Col 1', sortable: true, resizeable: true], [key:'col2', label:'Col 2', sortable: true, resizeable: true] ]" sortedBy="col1" rowsPerPage="20" paginatorConfig="[ template:'{PreviousPageLink} {PageLinks} {NextPageLink} {CurrentPageReport}', pageReportTemplate:'{totalRecords} total accounts', alwaysVisible:true, containers:'yui-dt0-paginator1' ]" rowExpansion="true" /> </div> </div> Any help? Thanks! Rollo

• Setting UIImage dimensions on UITableViewCell image

  - by bbrown

  I've got a standard UITableViewCell where I'm using the text and image properties to display a favicon.ico and a label. For the most part, this works really well since UIImage supports the ICO format. However, some sites (like Amazon.com say) have favicon.icos that make use of the ICO format's ability to store multiple sizes in the same file. Amazon stores four different sizes, all the way up to 48x48. This results in most images being 16x16 except for a few that come in at 32x32 or 48x48 and make everything look terrible. I have searched here, the official forum, the documentation, and elsewhere without success. I have tried everything that I could think of to constrain the image size. The only thing that worked was an undocumented method, which I'm not about to use. This is my first app and my first experience with Cocoa (came from C#). In case I wasn't clear in what I'm looking for, ideally the advice would center around setting the dimensions of the UIImage so that the 48x48 version would scale down to 16x16 or a method to tell UIImage to use the 16x16 version present in the ICO file. I don't necessarily need code: just a suggestion of an approach would do me fine. Does anyone have any suggestions? (I asked in the official forum as well because I've sunk more than a day into this already. If a solution is posted there, I'll put it here as well.)

• Adapting existing HTML/Javascript model to Titanium's latest release (v 0.9)

  - by Alan Neal

  In pre-0.9 versions of Titanium, one could simply specify an .html file (local or remote) in the tiapp.xml file and interact with it in the same manner as one would on a website. As of version 0.9, that is no the longer case. One creates their entire app dynamically. Unfortunately, this broke my previous implementation and, other than an updated Kitchen Sink, much of the new model and API calls are not covered in the documentation (e.g., createLabel). So, my question is this... What are the simplest steps for re-creating the previous effect (knowingly forgoing some of the advantages of the Titanium's latest approach if necessary)? My previous implementation was exactly as it functions on the website. The website has a single index.html file with no content other than links to JavaScript and style files. The document body's onload event called the first JavaScript function (located in the main script) and, from that point forth, the entire content was dynamically created. How can I set up the latest version of Titanium so that I am poised to do the exact same thing? BTW: Whereas I previously had the choice to keep the files local or remote, I don't believe that remote access (e.g., simply using the webView widget to point to the website) is viable. That's because pages displayed via the webView do not have access to most of the API. Since the iPhone and Safari browsers do not support the file input type, the only means for uploading files (something my app requires) is calling Titanium's function. Thanks in advance.

• Linux Kernel - Red/Black Trees

  - by CodeRanger

  I'm trying to implement a red/black tree in Linux per task_struct using code from linux/rbtree.h. I can get a red/black tree inserting properly in a standalone space in the kernel such as a module but when I try to get the same code to function with the rb_root declared in either task_struct or task_struct-files_struct, I get a SEGFAULT everytime I try an insert. Here's some code: In task_struct I create a rb_root struct for my tree (not a pointer). In init_task.h, macro INIT_TASK(tsk), I set this equal to RB_ROOT. To do an insert, I use this code: rb_insert(&(current-fd_tree), &rbnode); This is where the issue occurs. My insert command is the standard insert that is documented in all RBTree documentation for the kernel: int my_insert(struct rb_root *root, struct mytype *data) { struct rb_node **new = &(root->rb_node), *parent = NULL; /* Figure out where to put new node */ while (*new) { struct mytype *this = container_of(*new, struct mytype, node); int result = strcmp(data->keystring, this->keystring); parent = *new; if (result < 0) new = &((*new)->rb_left); else if (result > 0) new = &((*new)->rb_right); else return FALSE; } /* Add new node and rebalance tree. */ rb_link_node(&data->node, parent, new); rb_insert_color(&data->node, root); return TRUE; } Is there something I'm missing? Some reason this would work fine if I made a tree root outside of task_struct? If I make rb_root inside of a module this insert works fine. But once I put the actual tree root in the task_struct or even in the task_struct-files_struct, I get a SEGFAULT. Can a root node not be added in these structs? Any tips are greatly appreciated. I've tried nearly everything I can think of.

• Correlating traditional Windows joystick axes with HID

  - by Wade Williams

  I'm a bit confused on the description of joystick axes and I'm hoping that someone has a link or document which could help clear my confusion. I'm not a Windows guy, so trying to port some traditional Windows gameport code has me a bit confused. We all know about the common first three axes: X Y Z My understanding was that in the gameport-style interface the three other axes are: R U V However, looking in my IOHIDUsageTables (OS X), I see: kHIDUsage_GD_X = 0x30, /* Dynamic Value */ kHIDUsage_GD_Y = 0x31, /* Dynamic Value */ kHIDUsage_GD_Z = 0x32, /* Dynamic Value */ kHIDUsage_GD_Rx = 0x33, /* Dynamic Value */ kHIDUsage_GD_Ry = 0x34, /* Dynamic Value */ kHIDUsage_GD_Rz = 0x35, /* Dynamic Value */ kHIDUsage_GD_Vx = 0x40, /* Dynamic Value */ kHIDUsage_GD_Vy = 0x41, /* Dynamic Value */ kHIDUsage_GD_Vz = 0x42, /* Dynamic Value */ kHIDUsage_GD_Vbrx = 0x43, /* Dynamic Value */ kHIDUsage_GD_Vbry = 0x44, /* Dynamic Value */ kHIDUsage_GD_Vbrz = 0x45, /* Dynamic Value */ kHIDUsage_GD_Vno = 0x46, /* Dynamic Value */ This has me a bit confused due to the three R axis (though that does not appear to be uncommon) and the lack of a U axis. Two questions: 1) Can anyone confirm to what axis the traditional U axis would be? I saw one document describe it as "the axis for rudder pedals" leading me to believe it would be Rz. 2) Can anyone describe in more detail the typical usages of the V and Vbr axes? I understand the descriptions are "vector" and "relative vector,' respectively, but I'm having difficult visualizing what that means in terms of a physical device. All enlightenment and documentation pointers welcome.

• Virtual Lan on the Cloud -- Help Confirm my understanding?

  - by marfarma

  [Note: Tried to post this over at ServerFault, but I don't have enough 'points' for more than one link. Powers that be, move this question over there.] Please give this a quick read and let me know if I'm missing something before I start trying to make this work. I'm not a systems admin professional, and I'd hate to end up banging my head into the wall if I can avoid it. Goals: Create a 'road-warrior' capable star shaped virtual LAN for consultants who spend the majority of their time on client sites, and who's firm has no physical network or servers. Enable CIFS access to a cloud-server based installation of Alfresco Allow Eventual implementation of some form of single-sign-on ( OpenLDAP server ) access to Alfresco and other server applications implemented in the future Given: All Servers will live in the public internet cloud (Rackspace Cloud Servers) OpenVPN Server will be a Linux disto, probably Ubuntu 9.x, installed on same server as Alfresco (at least to start) Staff will access server applications and resources from client sites, hotels, trains, planes, coffee shops or their homes over various ISP, using their company laptops or personal home desktops. Based on my Research thus far, to accomplish this, I'll need: OpenVPN with Bridging Enabled to create a star shaped "virtual" LAN http://openvpn.net/index.php/open-source/documentation/miscellaneous/76-ethernet-bridging.html A Road Warrior Network Configuration, as described in this Shorewall article (lower down the page) http://www.shorewall.net/OPENVPN.html Configure bridge addressesing (probably DHCP) http://openvpn.net/index.php/open-source/faq.html#bridge-addressing Configure CIFS / Samba to accept VPN IP address http://serverfault.com/questions/137933/howto-access-samba-share-over-vpn-tunnel Set up Client software, with keys configured for access (potentially through a OpenVPN-Sa client portal) http://www.openvpn.net/index.php/access-server/download-openvpn-as/221-installation-overview.html

• Getting error: "This webpage is not available" for my chrome app's options page

  - by Don Rhummy

  My CRX had the proper html page options.html in it, the manifest declares it properly (it shows up as a link on the chrome://extensions page) but when I click that link, Chrome gives the error: This webpage is not available The webpage at chrome-extension://invalid/ might be temporarily down or it may have moved permanently to a new web address. It says "invalid" but the app runs perfectly well (all the content scripts run, the background created a database and saved to it). Why would it show as invalid? Why doesn't it have the extensions' id? Here's the manifest: { "manifest_version": 2, "name": "MyAPP", "description": "My App", "version": "0.0.0.32", "minimum_chrome_version": "27", "offline_enabled": true, "options_page": "options.html", "icons": { "16": "images/icon16.png", "48": "images/icon48.png", "128": "images/icon128.png" }, "app": { "background": { "scripts": [ "scripts/background.js" ] } }, "permissions": [ "unlimitedStorage", "fullscreen", { "fileSystem": [ "write" ] }, "background", "<all_urls>", "tabs" ] } Does it need to be declared in "web_accessible_resources"? Any idea what's wrong? Update Adding to "web_accessible_resources" does not fix the issue. I added everything on that page too. update 2 It looks like it might be a Chrome bug for packaged apps. When I remove the "app" section in the manifest, it works! This is a bug since the Chrome app documentation states that apps can have options pages: https://developer.chrome.com/apps/options.html

• Perform case-insensitive lookup on an Array in MongoDB?

  - by Hal

  So, I've decided to get my feet wet with MongoDB and love it so far. It seems very fast and flexible which is great. But, I'm still going through the initial learning curve and as such, I'm spending hours digging for info on the most basic things. I've search throughout the MongoDB online documentation and have spent hours Googling through pages without any mention of this. I know Mongo is still quite new (v1.x) so it explains why there isn't much information yet. I've even trying looking for books on Mongo without much luck. So yes, I've tried to RTFM with no luck, so, now I turn to you. I have an Array of various Hashtags nested in each document (ie: #apples, #oranges, #Apples, #APPLES) and I would like to perform a case-insensitive find() to access all the documents containing apples in any case. It seems that find does support some regex with /i, but I can't seem to get this working either. Anyway, I hope this is a quick answer for someone. Here's my existing call in PHP which is case sensitive: $cursor = $collection->find(array( "hashtags" => array("#".$keyword)))->sort(array('$natural' => -1))->limit(10); Help?

• Multiple undo managers for a text view

  - by Rui Pacheco

  Hi, I've a text view that gets its content from an attributed string stored in a model object. I list several of these model objects in a drawer and when the user clicks on one the text view swaps its content. I now need to also swap the undo manager for the text view. I initialise an undo manager on my model object and use undoManagerForTextView to return it to the text view, but something's not quite right. Strategically placed logging statements show me that everything's working as planned: on startup a new model object is initialised correctly and a non-null undo manager is always pulled by the text view. But when it comes to actually doing undo, I just can't get the behaviour I want. I open a window, type something and press cmd+z, and undo works. I open a window, type something, select a new model on the table, type something, go back to the first model and try to undo and all I get is a beep. Something on the documentation made me raise an eyebrow, as it would mean that I can't have undo with several model objects: The default undo and redo behavior applies to text fields and text in cells as long as the field or cell is the first responder (that is, the focus of keyboard actions). Once the insertion point leaves the field or cell, prior operations cannot be undone.

• Apache Axis: How to set call properties using code generated from wsdl2java?

  - by marc esher

  I'm using Apache Axis 1.4 (yes, the old one), with wsdl2java to generate the client code for a webservice. I'd like to set additional properties on the Call object before calling methods on the generated stub. For example, I'd like to set username, password, perhaps add or modify existing headers, and change the client handlers to use different implementations. Currently, I'm doing this by modifying the generated Stub class and calling the appropriate setters. However, I'd like to achieve this without touching the generated files. I"m confused, though, because the Stub class has: createCall() which creates the call object and sets some properties. Currently, this is where I'm modifying the generated source code; then, the Stub contains: clientMethod1(){ blahblah Call _call = createCall(); ...... _call.invoke(); } So I can't see a way that I can use the serviceLocator to get a stub, modify the properties I want to modify, and then use the stub to call the methods I want to call, given that the stub methods call createCall() and then call invoke. There doesn't appear to be a way to intercept the new Call object before it's invoked. So: How do you modify properties in the call without modifying the generated Stub class's source code? Thanks for info or even pointers to existing documentation.

• Odd behaviour with PHP's in_array function.

  - by animuson

  I have a function that checks multiple form items and returns either boolean(true) if the check passed or the name of the check that was run if it didn't pass. I built the function to run multiple checks at once, so it will return an array of these results (one result for each check that was run). When I run the function, I get this array result: Array ( [0] => 1 [1] => password [2] => birthday ) // print_r array(3) { [0]=> bool(true) [1]=> string(8) "password" [2]=> string(8) "birthday" } // var_dump The 'username' check passed and the 'password' and 'birthday' checks both failed. Then I am using simple in_array statements to determine which ones failed, like so: $results = $ani->e->vld->simulate("register.php", $checks); die(var_dump($results)); // Added after to see what array was being returned if (in_array("username", $results)) // do something if (in_array("password", $results)) // do something if (in_array("birthday", $results)) // do something The problem I'm having is that the 'username' line is still executing, even those 'username' is not in the array. It executes all three statements as if they were all true for some reason. Why is this? I thought maybe that the bool(true) was automatically causing the function to return true for every result without checking the rest of the array, but I couldn't find any documentation that would suggest that very odd functionality.

• php/mongodb: how does references work in php?

  - by harald

  hello, i asked this in the mongodb user-group, but was not satisfied with the answer, so -- maybe someone at stackoverflow can enlighten me: the question was: $b = array('x' => 1); $ref = &$b; $collection->insert($ref); var_dump($ref); $ref does not contain '_id', because it's a reference to $b, the handbook states. (the code snippet is taken from the php mongo documentation) i should add, that: $b = array('x' => 1); $ref = $b; $collection->insert($ref); var_dump($ref); in this case $ref contains the _id -- for those, who do not know, what the insert method of mongodb-php-driver does -- because $ref is passed by reference (note the $b with and without referencing '&'). on the other hand ... function test(&$data) { $data['_id'] = time(); } $b = array('x' => 1); $ref =& $b; test($ref); var_dump($ref); $ref contains _id, when i call a userland function. my question is: how does the references in these cases differ? my question is probably not mongodb specific -- i thought i would know how references in php work, but apparently i do not: the answer in the mongodb user-group was, that this was the way, how references in php work. so ... how do they work -- explained with these two code-snippets? thanks in advance!!!

• Can I embed a custom font in an iPhone application?

  - by Airsource Ltd

  I would like to have an app include a custom font for rendering text, load it, and then use it with standard UIKit elements like UILabel. Is this possible? I found these links: http://discussions.apple.com/thread.jspa?messageID=8304744 http://forums.macrumors.com/showthread.php?t=569311 but these would require me to render each glyph myself, which is a bit too much like hard work, especially for multi-line text. I've also found posts that say straight out that it's not possible, but without justification, so I'm looking for a definitive answer. EDIT - failed -[UIFont fontWithName:size:] experiment I downloaded Harrowprint.tff (downloaded from here) and added it to my Resources directory and to the project. I then tried this code: UIFont* font = [UIFont fontWithName:@"Harrowprint" size:20]; which resulted in an exception being thrown. Looking at the TTF file in Finder confirmed that the font name was Harrowprint. EDIT - there have been a number of replies so far which tell me to read the documentation on X or Y. I've experimented extensively with all of these, and got nowhere. In one case, X turned out to be relevant only on OS X, not on iPhone. Consequently I am setting a bounty for this question, and I will award the bounty to the first person who provides an answer (using only documented APIs) who responds with sufficient information to get this working on the device. Working on the simulator too would be a bonus. EDIT - it appears that the bounty auto-awards to the answer with the highest nunber of votes. Interesting. No one actually provided an answer that solved the question as asked - the solution that involves coding your own UILabel subclass doesn't support word-wrap, which is an essential feature for me - though I guess I could extend it to do so.

• Entity Framework lazy loading doesn't work from other thread

  - by Thomas Levesque

  Hi, I just found out that lazy loading in Entity Framework only works from the thread that created the ObjectContext. To illustrate the problem, I did a simple test, with a simple model containing just 2 entities : Person and Address. Here's the code : private static void TestSingleThread() { using (var context = new TestDBContext()) { foreach (var p in context.Person) { Console.WriteLine("{0} lives in {1}.", p.Name, p.Address.City); } } } private static void TestMultiThread() { using (var context = new TestDBContext()) { foreach (var p in context.Person) { Person p2 = p; // to avoid capturing the loop variable ThreadPool.QueueUserWorkItem( arg => { Console.WriteLine("{0} lives in {1}.", p2.Name, p2.Address.City); }); } } } The TestSingleThread method works fine, the Address property is lazily loaded. But in TestMultiThread, I get a NullReferenceException on p2.Address.City, because p2.Address is null. It that a bug ? Is this the way it's supposed to work ? If so, is there any documentation mentioning it ? I couldn't find anything on the subject on MSDN or Google... And more importantly, is there a workaround ? (other than explicitly calling LoadProperty from the worker thread...) Any help would be very appreciated PS: I'm using VS2010, so it's EF 4.0. I don't know if it was the same in the previous version of EF...

• How do I log from inside my web application in Tomcat 6.

  How do I log from within my web application deployed on Tomcat 6? Where should I expect the logging output to go (internal tomcat log files, or will another logfile be generated)?

• In-document schema declarations and lxml

  - by shylent

  As per the official documentation of lxml, if one wants to validate a xml document against a xml schema document, one has to construct the XMLSchema object (basically, parse the schema document) construct the XMLParser, passing the XMLSchema object as its schema argument parse the actual xml document (instance document) using the constructed parser There can be variations, but the essense is pretty much the same no matter how you do it, - the schema is specified 'externally' (as opposed to specifying it inside the actual xml document). If you follow this procedure, the validation occurs, sure enough, but if I understand it correctly, that completely ignores the whole idea of the schemaLocation and noNamespaceSchemaLocation attributes from xsi. This introduces a whole bunch of limitations, starting with the fact, that you have to deal with instance<-schema relation all by yourself (either store it externally or write some hack to retrieve the schema location from the root element of the instance document), you can not validate the document using multiple schemata (say, when each schema governs its own namespace) and so on. So the question is: maybe I am missing something completely trivial or doing it wrong? Or are my statements about lxml's limitations regarding schema validation true? To recap, I'd like to be able to: have the parser use the schema location declarations in the instance document at parse/validation time use multiple schemata to validate a xml document declare schema locations on non-root elements (not of extreme importance) Maybe I should look for a different library? Although, that'd be a real shame, - lxml is a de-facto xml processing library for python and is regarded by everyone as the best one in terms of performace/features/convenience (and rightfully so, to a certain extent)

• Testing warnings with doctest

  - by Eli Courtwright

  I'd like to use doctests to test the presence of certain warnings. For example, suppose I have the following module: from warnings import warn class Foo(object): """ Instantiating Foo always gives a warning: >>> foo = Foo() testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) >>> """ def __init__(self): warn("Boo!", UserWarning) If I run python -m doctest testdocs.py to run the doctest in my class and make sure that the warning is printed, I get: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) ********************************************************************** File "testdocs.py", line 7, in testdocs.Foo Failed example: foo = Foo() Expected: testdocs.py:14: UserWarning: Boo! warn("Boo!", UserWarning) Got nothing ********************************************************************** 1 items had failures: 1 of 1 in testdocs.Foo ***Test Failed*** 1 failures. It looks like the warning is getting printed but not captured or noticed by doctest. I'm guessing that this is because warnings are printed to sys.stderr instead of sys.stdout. But this happens even when I say sys.stderr = sys.stdout at the end of my module. So is there any way to use doctests to test for warnings? I can find no mention of this one way or the other in the documentation or in my Google searching.

  Hi there, after some hours of checking out documentation, I am somewhat desperate: Basically I need to populate a TabContainer with some TextBoxes, and some Checkboxes. All theses neatly arranged: Labels to the left, fields to the right. To have this done I use a TableContainer that I add to the TabContainer, create the TextFields and add them to the TableContainer. All is rendered ok. But when it comes to a checkbox, I can't find the trick to have a label displayed at all. If I: - add a label-attribute to creation statement say: var text8 = new dijit.form.CheckBox({ id:"zuschauer_" + i, value: "zuschauer", label:"fritt"}); Firefox comes up with a "containerNode is null" - Error try to add a tag: Nothing is shown (no error, but alas: no label): var text9 = dojo.create('<label>'); dojo.attr(text9,"for","zuschauer_" + i); dojo.attr(text9,"content","fritt"); try to add a div or somewhat else on the tablecontainer (disabled Labels): Firefox comes up whith: Error: uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIDOMHTMLDivElement.appendChild]" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: ... same is for created TextNodes... So how the hack: - Would I generate a label to a checkbox programatically (no html template possible, I've seen the code around, creating a checkbox but having a 'label for' on the html before. This would not be helpful, as I don't know how many checkboxes I need at designtime. These are to be genereated completly at runtime. - Would I have this very simple design done programatically, Must be easy, this is not rocket sience. Do I really need the TableContainer to have this done? - Can I create static text in a TableContainer? Any hint would be helpful Desperate Det

• How do you tune Eclipse IDE? How do you use Eclipse IDE?

  - by Kirzilla

  Hello, I've started to read the book "Code Craft" by Pete Goodliffe. The fourth chapter is about instruments that developer uses during his daily work; this chapter made me to review my work and I've seriously decided to make it easier with fully personalized IDE. Eclipse IDE is what I've started my learning from... I've read documentation and found that it's really easy to do tasks routine from Eclipse. We are using Mantis for tracking tasks and it was great surprise for me to find out Mantis Connector for Mylyn. Also I was pretty glad to see SVN client integrated into Eclipse IDE. Also I've found UML2 tool for Eclipse, but was disappointed because there is no any graphic interface for building diagramms. (Or, maybe, I'm was searching in wrong place?) What useful plugins do you use in your daily work? How do you use Eclipse for collaboration in your team? Do you have any links about intergration Eclipse IDE experience in dev. team? Thank you!

• Can't open Websphere Portal 7.0 Login Page after its integration with a custom user registry?

  - by jack_sparrow

  I am currently working on a project related to Websphere Portal 7.0 on Windows Server 2008 R2,64 bit. I am trying to integrate websphere portal with my custom user registry.I have completed all the steps required to implement custom user registry in portal as given in IBM documentation.I am adding my custom repository to the default federated repositories of Portal 7.0.I have made the required changes under VMM Federated CUR Properties section in wkplc.properties.I am using configengine.bat file to configure Portal with user registry. But even completing all the steps,when I am trying to open the Portal Login Page through http://ip-address:port_of_portal/wps/portal ,it is throwing an exception on the console: "Error 500: com.ibm.wps.resolver.data.exceptions.URIProcessingIOException: EJCBD0021E: The URI dav:fs-type1/themes/PageBuilder2/theme.html and parameters [['themeURI'=, 'mime-type'= could not be processed: [EJCBD0021E: The URI dav:fs-type1/themes/PageBuilder2/theme.html and parameters [['themeURI'=, 'mime-type'= could not be processed: EJPSG0002E: Requested Member does not exist.uid=portal,o=defaultWIMFileBasedRealm/null] " and in logs Systemout.log "EJPSB0005E: Exception occurred during creation of the principal with Name uid=portal,o=defaultWIMFileBasedRealm and Principal Type USER caused by com.ibm.portal.puma.MemberNotFoundException: EJPSG0002E: Requested Member does not exist.uid=portal,o=defaultWIMFileBasedRealm/null". Here,"portal" is administrative user in my custom user registry.I am able to access WAS using /ibm/console through user "portal".Please suggest some way to handle this issue.

• Mapping issue with multi-field primary keys using hibernate/JPA annotations

  - by Derek Clarkson

  Hi all, I'm stuck with a database which is using multi-field primary keys. I have a situation where I have a master and details table, where the details table's primary key contains fields which are also the foreign key's the the master table. Like this: Master primary key fields: master_pk_1 Details primary key fields: master_pk_1 details_pk_2 details_pk_3 In the Master class we define the hibernate/JPA annotations like this: @Id @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "idGenerator") @Column(name = "master_pk_1") private long masterPk1; @OneToMany(cascade=CascadeType.ALL) @JoinColumn(name = "master_pk_1", referencedColumnName = "master_pk_1") private List<Details> details = new ArrayList<Details>(); And in the details class I have defined the id and back reference like this: @EmbeddedId @AttributeOverrides( { @AttributeOverride( name = "masterPk1", column = @Column(name = "master_pk_1")), @AttributeOverride(name = "detailsPk2", column = @Column(name = "details_pk_2")), @AttributeOverride(name = "detailsPk2", column = @Column(name = "details_pk_2")) }) private DetailsPrimaryKey detailsPrimaryKey = new DetailsPrimaryKey(); @ManyToOne @JoinColumn(name = "master_pk_1", referencedColumnName = "master_pk_1", insertable=false) private Master master; The goal of all of this was that I could create a new master, add some details to it, and when saved, JPA/Hibernate would generate the new id for master in the masterPk1 field, and automatically pass it down to the details records, storing it in the matching masterPk1 field in the DetailsPrimaryKey class. At least that's what the documentation I've been looking at implies. What actually happens is that hibernate appears to corectly create and update the records in the database, but not pass the key to the details classes in memory. Instead I have to manually set it myself. I also found that without the insertable=true added to the back reference to master, that hibernate would create sql that had the master_pk_1 field listed twice in the insert statement, resulting in the database throwing an exception. My question is simply is this arrangement of annotations correct? or is there a better way of doing it?

• Authentication problem with Wufoo

  - by fudgey

  I set up a Wufoo form with admin only portions that will only show up if I am logged in. I read through the Wufoo API documentation and I can get the authenication to work, but when I try to access the form after I authenticate, it says I need to authenticate. This is what I have so far (subdomain, api key & form id changed) <?php error_reporting(E_ALL); ini_set('display_errors', 1); $curl1 = curl_init('http://fishbowl.wufoo.com/api/v3/users.xml'); curl_setopt($curl1, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl1, CURLOPT_USERPWD, 'AOI6-LFKL-VM1Q-IEX9:footastic'); curl_setopt($curl1, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl1, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl1, CURLOPT_FOLLOWLOCATION, false); curl_setopt($curl1, CURLOPT_USERAGENT, 'Wufoo Sample Code'); $response = curl_exec($curl1); $resultStatus = curl_getinfo($curl1); if($resultStatus['http_code'] == 200) { echo 'success!<br>'; } else { echo 'Call Failed '.print_r($resultStatus); } $curl2 = curl_init("http://fishbowl.wufoo.com/api/v3/forms/w7x1p5/entries.json"); curl_setopt($curl2, CURLOPT_HEADER, 0); curl_setopt($curl2, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec($curl2); curl_close ($curl2); echo $response; curl_close($curl1); ?> It doesn't matter if I close $curl1 before or after I call $curl2, I get the same message on my screen: success! You must authenticate to get at the goodies. and I know the api, subdomain and form id are all correct. And one last bonus question... can I do all of this using Ajax instead? - the page I will be displaying the form on will already be limited to admin access, so exposing the API shouldn't matter.
