• JSF, actionlistener at facelets

  - by asrijaal

  Hi there, I'm using JSF (Mojarra 1.2) with Richfaces (3.3.2) within some facelets which are used as portlets (I'm using the Jboss Portlet Bridge 2.0 here). Now I'm facing something strange: I've got an actionlistener on my <h:commandButton> which is triggered, when the button is clicked but when I simply reload the page, the action is executed everytime I load the page again. This happens only if I already triggered the action before. Is this behaviour normal? I should notice that Spring 2.5 is used to manage my beans, the mentioned beans are session-scope beans, maybe this is a interessting point?!

• Retrieving/simulating run-time "layer" functionality in Flash under ActionScript 3.

  - by Triynko

  Are there any AS3 classes to help arrange objects into layers, like in the designer, such that the objects all have the same parent? Obviously, I can use container clips to simulate layers, but I specifically want this kind of functionality for objects that have the same parent. My understanding is that the design-time notion of layers does not exist at run-time, and objects just have a depth index. I'm creating a class to simulate layering functionality with a single parent, but if one already exists, I'd like to check it out. On a side note... how do design-time layer masks manifest themselves at runtime in AS3? I thought maybe all objects on the masked layer share the same mask object, but the "mask" property appears to be null for all objects on the masked layer, even though they share the same parent timeline as the unmasked objects (i.e. unmasked layer object parent == masked layer object parent; therefore, no masked subcontainers appear to be in use).

• Beginning GWT and Java - wich is the best route when coming from LAMP background?

  - by Cambiata

  Hi! I've worked a lot with php/mysql on linux servers, including frameworks, orm etc. Now I want to give GWT and Java a try! Installing GWT SDK, Eclipse plugin etc and running a "Hello world" is no problem... The server is running automagically in the background... But when it comes to setting it up my self, there seems to be confusingly many options. Jetty? Tomcat? Glassfish? How are those related/combinable to/with Apache? Are there any good resources or tutorials for setting up java development and server environments suited for one like me with PHP background? Maybe pointing out the possiblities of running PHP and Java on the same server? Regards / Jonas

• AdMob Android integration - what permissions to ask for?

  - by AngryHacker

  In the various videos on the AdMob integration, I've seen that only permission to access the internet is asked for: <uses-permission android:name="android.permission.INTERNET" /> Not that I am an expert in advertising, but wouldn't AdMob need the user's geographic location as well, so that they can serve location specific ads? Or avoid serving certain ads based on a location, like maybe not offering me a Big Mac if I am in India or not adverting a ham sandwich if I am in an Arab country? If AdMob needs those permissions, how do I ask for them?

• Monitoring folders for changes

  - by blcArmadillo

  I'm working on a project that will require an application that watches a list of directories the user specifies for changes. Also, I'd like to give the users the option of running the application as a service or on an individual basis. Since users can choose to run it on an individual basis I don't think listening for some operating system event triggered by the addition or deletion of files (if such events exist) would be sufficient. I thought about maybe calculating a checksum for the deepest folder and then building up. I could then compare these checksums on subsequent scans to try and pinpoint where the changes have occurred. Would that be an appropriate solution; if not what would be the best way of doing this in an efficient manner? Also, I'm not quite sure what to tag this as so if you have any recommendations let me know and I'll as them as I see fit. EDIT: I'll need this method to work on Windows, OS X, and ideally Linux

• WxPython Incompatible With Snow Leopard?

  - by Alex

  Hello all, Recently I upgraded to Snow Leopard, and now I can't run programs built with wxPython. The errors I get are (from Eclipse + PyDev): import wx File "/var/tmp/wxWidgets/wxWidgets-13~231/2.6/DSTROOT/System/Library/Frameworks /Python.framework/Versions/2.6/Extras/lib/ python/wx-2.8-mac-unicode/wx/__init__.py", line 45, in <module> File "/var/tmp/wxWidgets/wxWidgets-13~231/2.6/DSTROOT /System/Library/Frameworks/Python.framework/Versions/2.6/Extras/lib /python/wx-2.8-mac-unicode/wx/_core.py", line 4, in <module> ImportError:/System/Library/Frameworks /Python.framework/Versions/2.6/Extras/lib/python /wx-2.8-mac-unicode/wx/_core_.so: no appropriate 64-bit architecture (see "man python" for running in 32-bit mode) I don't really understand them and would appreciate if you could help me to do so, also, if you do know what's going on, how can I go about fixing them? Maybe this has something to do with the fact that Snow Leopard is 64-bit? Thanks!!

• Using Inch or cm/mm from metric system for americans and canadians?

  - by gamma

  We're developing an international product that displays a ruler to the user. Now in Germany and many other countries its of course common to use the metric system: cm or mm. I'm aware that americans and canadians (and maybe others too) do still use inches, feet and yards. So the question is: will todays americans (and other inch-country-citizens) understand the metric system and take it for granted - or do they still love their inches so much that they'd rather die than use a product with incorrect measurements? ( sorry for being blunt ;) )

• iphone - Can't uninstall app on device

  - by wallou

  hey guys, I am testing my app on my jailbreaked iPhone and i noticed something strange. When i want to uninstall it on device i got no cross to delete the app. All the other apps (not mines) have the white circled cross. Whereas on the simulator i am able to delete my app. Is it because i run it on a jailbreak with a codesign workaround? Or maybe i am missing something in the app plist. Let me know if you have a clue. Wallou

• Has anyone ever encountered a Monad Transformer in the wild?

  - by martingw

  In my area of business - back office IT for a financial institution - it is very common for a software component to carry a global configuration around, to log it's progress, to have some kind of error handling / computation short circuit... Things that can be modelled nicely by Reader-, Writer-, Maybe-monads and the like in Haskell and composed together with monad transformers. But there seem to some drawbacks: The concept behind monad transformers is quite tricky and hard to understand, monad transformers lead to very complex type signatures, and they inflict some performance penalty. So I'm wondering: Are monad transformers best practice when dealing with those common tasks mentioned above?

• layout messed up once spinner has entries

  - by AndyAndroid

  Hello, I have <LinearLayout android:id="@+id/LinearLayoutPlayer" xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="wrap_content"> <Spinner android:id="@+id/Spinner01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="100"></Spinner> <ToggleButton android:text="@+id/ToggleButton01" android:id="@+id/ToggleButton01" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_weight="1"></ToggleButton> </LinearLayout> Which displays a spinner and next to it a toggle button. Everything okay so far. Of course the spinner need some entries, so I add to the spinner the attribute: android:entries="@array/myentries" The problem now is that the toggle button is a bit lower than the spinner and the botton of the toggle button is cut off, maybe 3 or 5 lines of pixels. Anyone an idea what is wrong here? Android is version 2.2 Thanks!

• ASP.NET connection pool question

  - by James Evans

  Does the same connection string used on two different physical servers hosting different web applications that talk to the same database draw connections from the same connection pool? Or are pooled connections confined to at the application level? I ask because I inherited a 7 year old .NET 1.1 web application which is riddled with in-line SQL, unclosed and undisposed sql connection and datareader objects. Recently, I was tasked to write a small web app that is hosted on another server and talks to the same database and therefore used the same database connection string. I created a LINQ object to read and write the one table required by the app. Now the original .NET 1.1 app is throwing exceptions like "Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached." Maybe these are unreleated, but wanted to get your opinions to make sure I cover all my bases. Thanks!

• How to programatically record the start and end of an MVC FileResult for logging of incomplete downl

  - by Richard

  Hi, I have been investigating how My ASP.NET MVC application can log unsuccessful / incomplete downloads. I have a controller handling the file requests which currently returns a FileResult. What I need to record is the IPAddress, filename and when the download started, then the same data and when it completed. I have looked at intercepting the request start and end with an HttpModule and also IIS7 failed request tracing but am not sure which route would be best and have this feeling that maybe I am missing an obvious answer to the problem. Does anyone have any suggestions or know of any alternatives as this seems like something many people would want to know from their web server? Thanks for your help

• Why does CGPDFPageGetDrawingTransform() crash with SIGABRT when specifying a rotation?

  - by David

  When I call CGPDFPageGetDrawingTransform() with a rotation argument, the application crashes. If I specify no rotation, there is no crash. Here is my drawLayer:inContext: method: - (void)drawLayer:(CALayer*)layer inContext:(CGContextRef)context { CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 1.0); CGRect boundingBox = CGContextGetClipBoundingBox(context); CGContextFillRect(context, boundingBox); //convert to UIKit native coodinate system CGContextTranslateCTM(context, 0.0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); //Rotate the pdf_page CGAffineTransform pfd_transform = CGPDFPageGetDrawingTransform(self.page, kCGPDFCropBox, self.frame, 58.46f, true); CGContextSaveGState (context); CGContextConcatCTM (context, pfd_transform); CGContextClipToRect (context, self.frame); CGContextDrawPDFPage (context, self.page); CGContextRestoreGState (context); } In the long run, I would like to rotate the pdf dynamically to follow a users heading. Maybe I am going at this all wrong... Thank you for your time.

• How to add a margin to a CheckedListBox in .NET?

  - by Xanatos

  I'm writing an windforms application using .NET (actually IronPython, but that's not relevant), and I have a CheckedListBox object in my GUI. It's working fine, it has about 20 items in a multicolumn layout. But I can't figure out how to give the thing a nice internal margin--I want to insert around 20 or 30 pixels of whitespace around the top, bottom, left, and right edges of the checkboxes. To be clear, I want the whitespace to appear between the border of the CheckedListBox and the Checkboxes inside it, not outside the whole component. Hopefully this is an easy answer, and I'm just missing it cause I'm new to programming in windows. If its not possible, I guess that'd be good to know too, so I don't waste anymore time with it. (If I were doing this in Swing (Java) I would be looking to set the Insets on my component, or maybe build up a compound border with some empty space in it.)

• Office Interop addins installer?

  - by jimbojw

  I have three C# Solutions in Visual Stuido 2008, one each for Word, Excel and PowerPoint using interop to hook various events. In each Solution, I have exactly one class, the one created by default when using File - New - Project - Visual C# - Office - 2007. Now that I have my addins working properly, it's time to create an installer. I understand that I may also have to distribute the PIAs. I would like my installer to register itself such that it can be uninstalled via the normal Add/Remove Programs mechanism. My organization is somewhat standardized around WiX for creating installers, but I'm open to any suggestions. How do I produce an MSI or EXE capable of installing my addins? GUI/wizard for the installer is not necessary. I'm happy to RTFM - so far all the tutorials I've found only explain how to create the project and do some of the coding. Maybe I'm using the wrong search terms? Thanks in advance for any help!

• ASP.NET MVC: What's the difference in concept between Service and Repository

  - by Richard77

  Hello, The question I'm asking is kind of subjective. I've seen twice, while exercising with real projects such as StoreFront, both Repository and Services. Sometimes they can just be folders or projects attached to the solution. But they contain classes and interfaces. So, I'd like to know what goes to the repository and what goes to the services. So far, I was familiar with repositories (we put methods and properties in the repository to reduce the complexity in the controller). How about the services? So, ASP.NET MVC: What's the difference in concept between Service and Repository? (Maybe none) My question is Kind of subjective, but I'd like to make sure that I'm not missing anything. Thanks for helping

• How to quickly analyse large MDB file

  - by Craig Johnston

  I need to know how to quickly analyse a large MDB file (about 1GB) to see which tables are causing it to be so big. Is there something will easily allow me to show a breakdown of which tables are responsible for how much data. I need to know whether it is just this one customer who is using the application differently, or whether there is genuinely a lot of data in the MDB. This MDB is currently causing the VB app to crash, and I need to know why it is so big so that I can maybe think about how to put some of the data into another 'archival' MDB. Migrating to SQL Server is not an option, unless the use of linked tables from an MDB is a realistic option.

• Minimalistic PHP template engine with caching but not Smarty?

  - by Pekka

  There are loads of questions for "the right" PHP template engine, but none of them is focused on caching. Does anybody know a lightweight, high-quality, PHP 5 based template engine that does the following out of the box: Low-level templating functions (Replacements, loops, and filtering, maybe conditionals) Caching of the parsed results with the possibility to set an individual TTL per item, and of course to force a reload programmatically Extremely easy usage (like Smarty's) Modest in polluting the namespace (the ideal solution would be one class to interact with from the outside application) But not Smarty. I have nothing against, and often use, Smarty, but I am looking for something a bit simpler and leaner. I took a look at Fabien Potencier's Twig that looks very nice and compiles templates into PHP code, but it doesn't do any actual caching beyond that. I need and want a template engine, as I need to completely separate code and presentation in a way that a HTML designer can understand later on, so please no fundamental discussions about whether template engines in PHP make sense. Those discussions are important, but they already exist on SO.

• IOS where to put the configuration of facebook sdk

  - by Carol Smith

  I am trying to integrated my IOS 7 application with Facebook SDK I following this official tutorial https://developers.facebook.com/docs/ios/getting-started which states Configure the .plist Follow these three steps: Create a key called FacebookAppID with a string value, and add the app ID there. Create a key called FacebookDisplayName with a string value, and add the Display Name you configured in the App Dashboard. Create an array key called URL types with a single array sub-item called URL Schemes. Give this a single item with your app ID prefixed with fb. This is used to ensure the application will receive the callback URL of the web-based OAuth flow. The finished .plist should look something like this: My question is where to put these values? They already put this image, maybe it helps you to answer me Edit The problem that I don't have any plist file in my framework in xcode and I can't add a new one because if i did, I would have to add all the variables that you see in the image but the tutorial just stated about some of them

• Can't read query string if default index file name is omitted?

  - by Mike

  Is there an issue with IIS or ASP Classic where *Request.ServerVariables("QUERY_STRING")* returns blank if no default file name is given in the URL? On my local developer machine, I can do http://localhost/xslt/?opcs/abc which returns "opcs/abc". However, on our ancient web server, it returns nothing. I have to explicitly give it the default file name in the URL. Like so http://localhost/xslt/default.asp?opcs/abc While nothing too major, it is a little bit of a annoyance. One way I can maybe think of remidying the problem is have Javascript read the URL and return everything after the ?. Unfortunately, I do not know what version of IIS or ASP we are using. Thank you.

• Transportation Web App - utilizing google or bing map api

  - by BillS

  I am working on a transportation web app and I am having a bit of a problem. First, I want to be able to define a shipping corridor, say like I-95 between Baltimore MD and Richmond VA. And store what parameters I need to define this route. Users will then use a web interface and can select various routes, in this case, I-95. Vendors will be posting constantly changing pickup locations in the application database which have a shelf life of about 2 days. Some of these locations maybe along this route. I am storing the LAT and LONG for the specific location right now. If any of these points ARE along or within 2 mile of the route (just off the highway basically - the ideal check would based on an actual highway exit but at this point anything would work), I want them to show up in my search results. Any ideas or suggestions?

• How to update individual files in a war file

  - by ziggy

  Hi guys, I am doing some research in the way i can deploy an application efficiently using a war file. What i currently do is i deliver the war file everytime there is a release. This means everytime there is a change no matter how small the change is i have to build and deliver all files that make up the application. I am thinking that maybe this is not the correct way to do this. For example if there is a change to a css file i have to rebuild the war file which will include all file. This includes recompiling all *.java files as well. In the above example, is it possible to build a war file with just the css file and deploy it to the tomcat server and have Tomcat just replace the css file and leave everything else as is?

• javascript keypress function: case-insensitive a-z, numbers and a few special chars?

  - by user239831

  hey guys, $('.s').keyup(function(e) { if (!/[A-Za-z0-9]/.test(String.fromCharCode(e.which))) { return false; } I wonder what is the best regex solution for my application. I have an ajax-based search that should just trigger the search when actual characters are pressed like a-Z (upper and lowercase), numbers and maybe a questionmark, a dash(hyphen), and an exclamation mark. Also the spacebar should be enabled. Otherwise the ajax search would be triggered as well if the shift-, option, or control-key, is pressed. What's the easiest regex pattern to understand here? thank you for your help

• simple div containing span won't size correctly

  - by brad

  I thought I was pretty knowledgeable about CSS but this simple problem baffles me. <div><span>sample text</span></div> results in the div's height being smaller than the height of the span if the span has padding. I realize that there are ways to use "float" to make the div size correctly, but floats always seem to introduce undesired side effects. Isn't there a clean simple way to tell the div to size to fit its contents? Seems pretty basic to me. Maybe I'm missing something.

• Problem with setContentBorderThickness:forEdge: not actually setting the value

  - by jxpx777

  I'm trying to use setContentBorderThickness:forEdge: to create a bottom bar in a Cocoa application. mipadi was on to something, but in testing it out, I think maybe this is a slightly different problem: -(void) adjustContentBorderBasedOnArrayControllerSelection{ if(([[self.resultsArrayController selectionIndexes] count] == 0)){ [[self window] setContentBorderThickness:40.0f forEdge:CGRectMinYEdge]; NSLog(@"%f", [[self window] contentBorderThicknessForEdge:CGRectMinYEdge]); } else { [[self window] setContentBorderThickness:60.0f forEdge:CGRectMinYEdge]; NSLog(@"%f", [[self window] contentBorderThicknessForEdge:CGRectMinYEdge]); } } Both of those NSLog() messages show the thickness value is 0.0 even after I explicitly set it. Anyone know what's up with that?
