• Myfaces extensionfilter overriding renderkit? (Tree2 component)

  - by Mike

  I've pulled in the tree2 component (from Tomahawk 1.1.9). Had used the simpler Tree component on previous projects, and this one just looks a bit nicer. Running on websphere 6.1.x and set the server side flag that's needed (com.ibm.ws.webcontainer.invokefilterscompatibility=true) and set the extensionfilter accordingly. Everything's good, and works as expected. Here's the issue: - on a page being included on this one (just some typical footer type info with NO myfaces widgets), there's some embedded html that's getting flagged with warnings in the systemout console). These look like org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 475. Surroundings: 'span id="tile:footr:viewFragm'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 479. Surroundings: 'a id="tile:footr:viewFragment'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 492. Surroundings: 'a id="tile:footr:viewFragment'. The problem isn't necessarily with the html (which should be cleaned up regardless :-). IF I don't include myfaces, I don't get these warning messages with the default ibm jsf renderer (using jsf 1.1 still). Obviously, IBM's implementation is a bit more lax than myFaces. The page has nothing to do with myfaces at all. The reason for needing the extension filter is that it needs (for the Tree2 anyways, I know it does more for file upload) to intercept requests and then stick some .js includes on the page. Investigated this a bit, and I've included this filter in my web.xml, but it is NO longer fronting the faces servlet. So, the filter is instantiated at startup, but is never executed. Since the filter isn't in place, I've had to hard code in the includes for the 2 .js files into my page Now, the tree2 gets rendered properly, AND I'm not getting the warnings from above, because with the extentionfilter not being called, its using the IBM renderkit ;-) I'm a bit concerned that when the extension filter is in place, everything is being rendered by myFaces, rather than IBM's renderkit (i.e. All I want is myfaces/tomahawk to render the tree2 only, and let the ri do everything else) Can anyone confirm this? When you use myfaces/tomahawk, is it doing all the rendering for the whole application, or just the page any tomahawk widget is on? Thanks for any thoughts on this mike

  So i have the following query Select id, [First], [Last] , [Business] as contactbusiness, (Case When ([Business] != '' or [Business] is not null) Then [Business] Else 'No Phone Number' END) from contacts The results look like id First Last contactbusiness (No column name) 2 John Smith 3 Sarah Jane 0411 111 222 0411 111 222 6 John Smith 0411 111 111 0411 111 111 8 NULL No Phone Number 11 Ryan B 08 9999 9999 08 9999 9999 14 David F NULL No Phone Number I'd expect record 2 to also show No Phone Number If i change the "[Business] is not null" to [Business] != null then i get the correct results id First Last contactbusiness (No column name) 2 John Smith No Phone Number 3 Sarah Jane 0411 111 222 0411 111 222 6 John Smith 0411 111 111 0411 111 111 8 NULL No Phone Number 11 Ryan B 08 9999 9999 08 9999 9999 14 David F NULL No Phone Number Normally you need to use is not null rather than != null. whats going on here?

• How to store Ruby method references in a database?

  - by Mad Wombat

  I am writing my first rails app. It needs to aggregate some data from multiple sites and for each site I have a unique way of getting the data (some provide RSS, some JSON, for some I scrape the HTML etc.). These will run on schedule, probably as a rake task from cron. It seems logical to store the sites and relevant information in a model, but I am not sure where to put unique data retrieval methods. Do I store method names in the model? Do I just name the methods the same as site name and call them that way? Basically, I need a way to read a list of sites and call appropriate method for each site. What is the Ruby on Rails way to do it?

• Can I programatically get hold of the Autos/local variables that is shown when debugging?

  - by Stefan

  Im trying to build an error-logger that loggs running values that is active in the function that caused the error. (just for fun so its not a critical problem) When going in break-mode and looking at the locals-tab and autos-tab you can see all active variables (name, type and value), it would be useful to get hold of that for logging purposes when an error occur and on some other occasions. For my example, I just want to find all local variables that are of type string and integer and store the name and value of them. Is this possible with reflection? Any tips or pointers that get me closer to my goal would be very appreciated. I have toyed with using expression on a specifik object (a structure) to create an automapper against a dataset, but I have not done anything like what I ask for above, so please make me happy and say its possible. Thanks.

• Get domain user from IPAddress or Hostname in .Net

  - by Duracell

  We're trying to implement a custom solution for Growl for Windows. We tell the Growl client to subscribe to notifications from our server. The server then gets a message from the client via the GNTP (Growl messaging protocol). We require the name of the user logged into the client machine in order to do database lookups. The GNTP does not provide this information. So, we have a connected client socket (and thus, IP address) and a message from this client containing its machine name. Is there any possible way to determine the username of the user who is logged into the specified machine? We have access to windows domain services.

• Titanium webview bug or "feature"? Numbers converted to telephone links

  - by Alan Neal

  I can't stop Titanium's webview from converting numbers to telephone links. For instance, let's say I programmatically set the innerHTML of a div called test to 96840664702 and then write javascript... alert(document.getElementById('test').innerHTML In Mobile Safari on the iPhone, Firefox, etc., the alert will read "96840664702". If I point Titanium's webview to the same page, the alert will read: <a href="tel:96840664702" x-apple-data=detectors="true">96840664702</a> How can I globally disable the data-detectors? I tried a couple meta-tags... <meta name=”format-detection” content=”telephone=no” > <meta name="x-" http-equiv="x-rim-auto-match" forua="true" content="none"/> ... but they didn't work. I couldn't find a reference for a meta tag that specifically mentioned Apple's detectors. Again, it's only a problem in Titanium's webview. It works everywhere else.

• XML Deserialization in VB/VBA

  - by oharab

  I have a set of VBA classes in an MS Access database. I have an xml string with data I want to create new classes with. Other than setting each property individually, is there an easy way to deserialize the XML into my object? I've seen the code using the TypeLib library Public Sub ISerializable_Deserialize(xml As IXMLDOMNode) Dim tTLI As TLIApplication Dim tInvoke As InvokeKinds Dim tName As String Dim tMem As MemberInfo tInvoke = VbLet For Each tMem In TLI.ClassInfoFromObject(Me).Members tName = LCase(tMem.Name) CallByName Me, tMem.Name, VbLet, xml.Attributes.getNamedItem(tName).Text Next tMem End Sub but this doesn't seem to work with the standard class modules. I get a 429 error: ActiveX Component Cannot Be Created Can anyone else help me out? I'd rather not have to set each propery by hand if I can help it, some of these classes are huge!

• WCF Proxy generation

  - by dragonfly

  Hi, I'm generating proxy using svcutil tool. My contract methods return objects of particular type. However generated proxy client interface has return value of type object. What is more I get exception with message: System.ServiceModel.FaultException`1[System.ServiceModel.ExceptionDetail] : The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/:name. The InnerException message was 'XML 'Element' 'http://tempuri.org/:name' does not contain expected attribute 'http://schemas.microsoft.com/2003/10/Serialization/:Type'. The deserializer has no knowledge of which type to deserialize. Check that the type being serialized has the same contract as the type being deserialized.'. Please see InnerException for more details. Any ideas what's going on?

• Call named routes in CakePHP as the same way in Ruby on Rails

  - by Lucas Renan

  How can I call a route (in the view) in CakePHP as the same way in Rails? Ruby on Rails routes.rb map.my_route '/my-route', :controller => 'my_controller', :action => 'index' view link_to 'My Route Name', my_route_path CakePHP routes.php Router::connect('/my-route', array('controller' => 'my_controller', 'action' => 'index')); view $html->link('My Route Name', '/my-route'); But I think the Rails way is better, because I can make changes in the "url" and I don't need changes the code of the views.

• Django query if field value is one of multiple choices

  - by Nathan

  Say I want to model a system where a piece of data can have multiple tags (e.g. a question on a StackOverflow is the data, it's set of tags are the tags). I can model this in Django with the following: class Tag(models.Model): name = models.CharField(10) class Data(models.Model): tags = models.ManyToManyField(Tag) Given a set of strings, what's the best way to go about finding all Data objects that have one of these strings as the name of a tag in their tag list. I've come up with the following, but can't help thinking there is a more "Djangonic" way. Any ideas? tags = [ "foo", "bar", "baz" ] q_objects = Q( tags__name = tags[0] ) for t in tags[1:]: q_objects = q_objects | Q( tags__name = t ) data = Data.objects.filter( q_objects ).distinct()

• In Django, what's the best way to handle optional url parameters from the template?

  - by Thierry Lam

  I have the following type of urls which are both valid: hello/ hello/1234/ My urls.py has the following: urlpatterns = patterns('hello.views', url(r'^$', 'index', name='index'), url(r'^(?P<user_id>\d+)/$', 'index', name='index'), ) In my views.py, when I pass user_id to the template, it defaults to 0 if not specified. My template looks like the following, I'm using namespace hello for my hello app: {% url hello:index user_id %} If user_id is not specified, the url defaults to hello/0/. The only way I can think of preventing the default 0 from showing in the url is by an if stmt: {% if user_id %} {% url hello:index user_id %} {% else %} {% url hello:index %} {% endif %} The above will give me hello/ if there are no user_id and hello/1234/ if it's present. Is the above solution the best way to solve this issue?

• How to fix "could not find a base address that matches schema http"... in WCF

  - by Craig Shearer

  I'm trying to deploy a WCF service to my server, hosted in IIS. Naturally it works on my machine :) But when I deploy it, I get the following error: This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Googling on this, I find that I have to put a serviceHostingEnvironment element into the web.config file: <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://mywebsiteurl"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> But once I have done this, I get the following: Could not find a base address that matches scheme http for the endpoint with binding BasicHttpBinding. Registered base address schemes are [https]. It seems it doesn't know what the base address is, but how do I specify it? Here's the relevant section of my web.config file: <system.serviceModel> <serviceHostingEnvironment> <baseAddressPrefixFilters> <add prefix="http://mywebsiteurl"/> </baseAddressPrefixFilters> </serviceHostingEnvironment> <behaviors> <serviceBehaviors> <behavior name="WcfPortalBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="BasicHttpBinding_IWcfPortal" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" receiveTimeout="00:10:00" sendTimeout="00:10:00" openTimeout="00:10:00" closeTimeout="00:10:00"> <readerQuotas maxBytesPerRead="2147483647" maxArrayLength="2147483647" maxStringContentLength="2147483647"/> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="WcfPortalBehavior" name="Csla.Server.Hosts.Silverlight.WcfPortal"> <endpoint address="" binding="basicHttpBinding" contract="Csla.Server.Hosts.Silverlight.IWcfPortal" bindingConfiguration="BasicHttpBinding_IWcfPortal"> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel> Can anybody shed some light on what's going on and how to fix it?

• Hierarchy based aggregation

  - by Ganapathy Subramaniam

  I have a hierarchy table in SQL Server 2005 which contains employees - managers - department - location - state. Sample table for hierarchy table: ID Name ParentID Type 1 PA NULL 0 (group) 2 Pittsburgh 1 1 (subgroup) 3 Accounts 2 1 4 Alex 3 2 (employee) 5 Robin 3 2 6 HR 2 1 7 Robert 6 2 Second one is fact table which contains employee salary details ID and Salary. Sample data for fact table: ID Salary 4 6000 5 5000 7 4000 Is there any good to way to display the hierarchy from hierarchy table with aggregated sum of salary based on employees. Expected result is like Name Salary PA 15000 (Pittsburgh + others(if any)) Pittusburgh 15000 (Accounts + HR) Accounts 11000 (Alex + Robin) Alex 6000 (direct values) Robin 5000 HR 4000 Robert 4000 In my production environment, hierarchy table may contain 23000+ rows and fact table may contain 300,000+ rows. So, I thought of providing any level of groupid to the query to retrieve just its children and its corresponding aggregated value. Any better solution?

• Pass-by-Reference Error

  - by TK

  I have a hook system setup... which is working on localhost... I put it live and get an error saying "Warning: Call-time pass-by-reference has been deprecated". Now, apparently the work around is to remove all "&" from your function calls, ie foo(&$me) to foo($me) and then in foo's function definition do "function foo(&$me)". However, I can not do this... because my hooks accept an array as arguments, I need a work around for this. Like I can use "run_hooks ( 'hook-name', $me );" or "run_hooks ( 'hook-name', array ( $me, $another_var, etc... ) )"; So this means I can not use "function run_hooks ( $hook_name, &$arguments )" because I'll get an error in php saying it can not pass "array()" as reference... Any ideas an a work around? Thanks.

• windows 2008 task scheduled batch file runs forever

  - by phill

  I currently have the following batch running in windows 2008 task scheduler. mysql --user=bobdb --password=letmein --force --named-commands --local-infile=1 --execute="insert into bobdb.attendees (name) values ('bob');insert into bobdb.attendees (name) values ('rick');" It executes nicely when I run it from a command prompt and it executes when I force it to run and it executes when it is scheduled to run. My issue is when it does run, the task scheduler seems to keep it running until it hits a timeout. Is there a command to tell it when it is finished running in the batch file so it doesn't throw a timeout error? thanks in advance

• Doubt about adopting CI (Hudson) into an existing automated Build Process (phing, svn)

  - by maraspin

  OUR CURRENT BUILD PROCESS We're a small team of developers (2 to 4 people depending on project) who currently use Phing to deploy code to a staging environment, before going live. We keep our code in a SVN repo, where the trunk holds current active development and, at certain times, we do make branches that we test and then (if successful), tag and export to the staging env. If everything goes well there too, we finally deploy'em in production servers. Actions are highly automated, but always triggered by human intervention. THE DOUBT We'd now like to introduce Continuous Integration (with Hudson) in the process; unfortunately we have a few doubts about activity syncing, since we're afraid that CI could somewhat interfere with our build process and cause certain problems. Considering that an automated CI cycle has a certain frequency of automatically executed actions, we in fact only see 2 possible cases for "integration", each with its own problems: Case A: each CI cycle produces a new branch with its own name; we do use such a name to manually (through phing as it happens now) export the code from the SVN to the staging env. The problem I see here is that (unless specific countermeasures are taken) the number of branches we have can grow out of control (let's suppose we commit often, so that we have a fresh new build/branch every N minutes). Case B: each CI cycle creates a new branch named 'current', for instance, which is tagged with a unique name only when we manually decide to export it to staging; the current branch, at any case is then deleted, as soon as the next CI cycle starts up. The problem we see here is that a new cycle could kick in while someone is tagging/exporting the 'current' branch to staging thus creating an inconsistent build (but maybe here I'm just too pessimist, since I confess I don't know whether SVN offers some built-in protection against this). With all this being said, I was wondering if anyone with similar experiences could be so kind to give us some hints on the subject, since none of the approaches depicted above looks completely satisfing to us. Is there something important we just completely left off in the overall picture? Thanks for your attention &, in advance, for your help!

• Different log4j patterns on the same same file depending on log level?

  - by gorca

  Hi, I'd like for log events of type WARN or higher to show the class name. All others would not show the class name. this is both to simplify the log and to not have the performance hit on lower events such as TRACE. This must all go to the same log file. For example, right now, I have this on my log file: 2010-04-06 18:50:16,416 [main] INFO org.nyjord.lib.gather.TempMachine - initialised successfuly. 2010-04-06 18:50:16,416 [main] FATAL org.nyjord.lib.gather.TempMachine - not all paths could be located I would prefer this ON THE SAME FILE: 2010-04-06 18:50:16,416 [main] INFO - initialised successfuly. 2010-04-06 18:50:16,416 [main] FATAL org.nyjord.lib.gather.TempMachine - not all paths could be located Help would be really welcome.

• .gitconfig error

What did I do wrong? The error message doesn't help much either: "fatal: bad config file line 13 in c:/Users/Tanner/.gitconfig" [gui] recentrepo = C:/Users/Tanner/Desktop/FIRST 2010 Beta/Java/LoganRover [user] name = Tanner Smith email = [email protected] [merge "labview"] name = LabView 3-Way Merge driver = “C:\Program Files\National Instruments\Shared\LabVIEW Merge\LVMerge.exe” “C:\Program Files\National Instruments\LabVIEW 8.6\LabVIEW.exe” %O %B %A %A recursive = binary And I'm not seeing a line 13, but usually that would mean something is wrong at the end?

• Visual Studio Windows Forms Designer keyboard shortcuts

  - by Dan Tao

  Extremely basic question. Are there common actions I can perform using keyboard shortcuts in the Windows Forms designer in Visual Studio (2008)? Alternately, could I add my own keyboard shortcuts (either through settings or macros)? It'd really be nice if I could, for example, set a control to dock/undock in its parent container by typing Alt+D. Or if I could set a control's name just by typing Alt+N and typing the name. Things like that. It's just kind of tedious to click on the item, scroll in the Properties grid to the property I want to change, type the new value, scroll to the next property I want to change, etc. Which is why I have a feeling this functionality is in there already, or is easily configurable, and I just don't know about it.

• .net activeX object

  Hi, I am trying to use my .net image editor user control as an activeX object in a web form. After internet search, I created a asp.net web site from VS2008 and added the following code <object classid="res/ImageEditor.dll#ImageEditor.Editor" height="400" width="400" id="myControl1" name="myControl1" > </object> <INPUT id="Button1" type="button" value="Btn" name="Btn" onclick="return Button1_onclick()"> </script> <script language=javascript> function Button1_onclick() { alert(document.getElementById("myControl1").WatermarkText); } </script> I have two problems 1-) When i first create the project i see the user control on browser but, after rebuilding the user control and changing the dll file at web site, the object no more appears on browser. Instead i see something like an error image. 2-) i can not access public properties. The user control is marked as "make com visible", and register for com is checked at properties.

• Codeigniter: How to build an edit form that uses form validation and re-population?

  - by Sergio

  Hi There, I have a simple form in codeigniter that I wish to use for the editing or records. I am at the stage where my form is displayed and the values entered into the corresponding input boxes. This is done by simply setting the values of said boxes to whatever they need to be in the view: <input type="text" value="<?php echo $article['short_desc'];?>" name="short_desc" /> But, if I wish to use form_validation in codeigniter then I have to add thos code to my mark-up: <input value="<?php echo set_value('short_desc')?>" type="text" name="short_desc" /> So not the value can be set with the set_value function should it need to be repopulated on error from the post data. Is there a way to combine the two so that my edit form can show the values to be edited but also re-populate? Thanks

• Switching from LinqToXYZ to LinqToObjects

  - by spender

  In answering this question, it got me thinking... I often use this pattern: collectionofsomestuff //here it's LinqToEntities .Select(something=>new{something.Name,something.SomeGuid}) .ToArray() //From here on it's LinqToObjects .Select(s=>new SelectListItem() { Text = s.Name, Value = s.SomeGuid.ToString(), Selected = false }) Perhaps I'd split it over a couple of lines, but essentially, at the ToArray point, I'm effectively enumerating my query and storing the resulting sequence so that I can further process it with all the goodness of a full CLR to hand. As I have no interest in any kind of manipulation of the intermediate list, I use ToArray over ToList as there's less overhead. I do this all the time, but I wonder if there is a better pattern for this kind of problem?
