  • Why can't Doctrine retrieve my model data?

    - by scottm
    So, I'm trying to use Doctrine to retrieve some data. I have some basic code like this: $conn = Doctrine_Manager::connection(CONNECTION_STRING); $site = Doctrine_Core::getTable('Site')->find('00024'); echo $site->SiteName; However, this keeps throwing a SQL error that 'column siteid does not exist'. When I look at the exception the SQL query is this (you can see the error is that the inner_tbl alias for siteid is set to s__siteid, so querying inner_tabl.siteid is what's broken): SELECT TOP 1 [inner_tbl].[siteid] AS [s__siteid] FROM (SELECT TOP 1 [s].[siteid] AS [s__siteid], [s].[name] AS [s__name], [s].[address] AS [s__address], [s].[city] AS [s__city], [s].[zip] AS [s__zip], [s].[state] AS [s__state], [s].[region] AS [s__region], [s].[callprocessor] AS [s__callprocessor], [s].[active] AS [s__active], [s].[dateadded] AS [s__dateadded] FROM [Sites] [s] WHERE ([s].[siteid] = '00024') ) AS [inner_tbl] Why is the query being generated this way? Could it be the way the Yaml schema is laid out?

  • Android Custom Dialog NullPointerException

    - by Kyle Hughes
    I cannot for the life of me figure out why I'm getting a NullPointerException. When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image: private OnClickListener coverListener = new OnClickListener() { public void onClick(View v) { showDialog(DIALOG_COVER); } }; DIALOG_COVER is set to = 0. The associated onCreateDialog looks like this: protected Dialog onCreateDialog(int id) { Dialog dialog; switch(id) { case DIALOG_COVER: dialog = new Dialog(mContext); dialog.setContentView(R.layout.cover_dialog); dialog.setTitle(book.getTitle()); ImageView coverLarge = (ImageView)findViewById(R.id.coverLarge); coverLarge.setImageBitmap(book.getCover()); break; default: dialog = null; } return dialog; } For reference, this is cover_dialog.xml: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/coverDialog" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp"> <ImageView android:id="@+id/coverLarge" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="fitStart" /></LinearLayout> Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat: 06-08 13:29:17.727: ERROR/AndroidRuntime(2220): Uncaught handler: thread main exiting due to uncaught exception 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): java.lang.NullPointerException 06-08 13:29:17.757: ERROR/AndroidRuntime(2220): at org.kylehughes.android.brarian.AndroidBrarian.onCreateDialog(AndroidBrarian.java:259) The line in question refers to this line inside of onCreateDialog: coverLarge.setImageBitmap(book.getCover()); Basically, I don't get why coverLarge is null at that point. Any help would be much appreciated.

  • System.Dynamic bug?

    - by ControlFlow
    While I playing with the C# 4.0 dynamic, I found strange things happening with the code like this: using System.Dynamic; sealed class Foo : DynamicObject { public override bool TryInvoke( InvokeBinder binder, object[] args, out object result) { result = new object(); return true; } static void Main() { dynamic foo = new Foo(); var t1 = foo(0); var t2 = foo(0); var t3 = foo(0); var t4 = foo(0); var t5 = foo(0); } } Ok, it works but... take a look at IntelliTrace window: So every invokation (and other operations too on dynamic object) causes throwing and catching strange exceptions twice! I understand, that sometimes exceptions mechanism may be used for optimizations, for example first call to dynamic may be performed to some stub delegate, that simply throws exception - this may be like a signal to dynamic binder to resolve an correct member and re-point delegate. Next call to the same delegate will be performed without any checks. But... behavior of the code above looks very strange. Maybe throwing and catching exceptions twice per any operation on DynamicObject - is a bug?

  • How to test a DAO with JPA implementation ?

    - by smallufo
    Hi I came from the Spring camp , I don't want to use Spring , and am migrating to JavaEE6 , But I have problem testing DAO + JPA , here is my simplified sample : public interface PersonDao { public Person get(long id); } This is a very basic DAO , because I came from Spring , I believe DAO still have it value , so I decided to add a DAO layer . public class PersonDaoImpl implements PersonDao , Serializable { @PersistenceContext(unitName = "test", type = PersistenceContextType.EXTENDED) EntityManager entityManager ; public PersonDaoImpl() { } @Override public Person get(long id) { return entityManager .find(Person.class , id); } } This is a JPA-implemented DAO , I hope the EE container or the test container able to inject the EntityManager. public class PersonDaoImplTest extends TestCase { @Inject protected PersonDao personDao; @Override protected void setUp() throws Exception { //personDao = new PersonDaoImpl(); } public void testGet() { System.out.println("personDao = " + personDao); // NULL ! Person p = personDao.get(1L); System.out.println("p = " + p); } } This is my test file . OK , here comes the problem : Because JUnit doesn't understand @javax.inject.Inject , the PersonDao will not be able to injected , the test will fail. How do I find a test framework that able to inject the EntityManager to the PersonDaoImpl , and @Inject the PersonDaoImpl to the PersonDao of TestCase ? I tried unitils.org , but cannot find a sample like this , it just directly inject the EntityManagerFactory to the TestCast , not what I want ...

  • How to handle missing files on MVC

    - by kaivalya
    What is your preferred way to handle hits to files that does not exist on your MVC app. I have couple of web apps runing with MVC and they are constantly getting hits for files folders etc. that does not exist in the app structure. Apps are throwing exception: The controller for path could not be found or it does not implement IController I am trying to find out the best way to handle this. I have 3 global routes on my global.asax file (see below) and at this point I am happy with that simple definition. I know if I added route definition for all controllers then I can add a definition to ignore the rest and handle these hits but if it will be possible to solve this problem without it, I do not want to add route definitions for each controller which I believe will flood the route definitions and also add a layer of maintenance which I don't like. //Aggregates 2nd level routes.MapRoute( "AggregateLevel2", "{controller}/{action}/{id}/{childid}/{childidlevel2}", new { controller = "Home", action = "Index", id = "", childid = "", childidlevel2 = "" } ); //Aggregates 1st level routes.MapRoute( "AggregateLevel1", "{controller}/{action}/{id}/{childid}", new { controller = "Home", action = "Index", id = "", childid = "" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } );

  • [ASP.NET] Difficulties using custom control - RichTextEditor

    - by Chris
    I am working on a school project that uses ASP.NET. I found this TextEditor control ( http://blogs.msdn.com/kirti/archive/2007/11/10/rich-text-editor-is-here.aspx ) that I am trying to include but it isn't working. The error I am getting is: Error Rendering Control - TextEditor. An unhandled exception has occurred. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index. I see this error when I go Design part of the editor. I just don't understand this error at all. Also I am a lil bit confused as there is no parameter called index. :( What I have done is reference the binary in my project and then on the page I am trying to use it have registered its namespace and assembly with this line: <%@ Register Assembly="RichTextEditor" Namespace="AjaxControls" TagPrefix="rtt" %> I then go ahead and try to add the control to the page with this line of code: <rtt:richtexteditor ID="TextEditor" Theme="Blue" runat="server" /> Any help would be much appreciated. I haven't done anything like add a custom control before.

    - by Pratik
    Hi there, I am using RestWebservice for few basic operations , like creating/searching. The request xml looks something like this <customer> <name/> ..... </customer> For a successful operation I return the same customer XML with extra fields populated in it(eg. systemId etc which we blank in the request) . with Response.Status=2000 For an unsuccessful operation i return something like this with different error codes . e.g Response.Status = 422(Unprocessable entity) Response.Status= 500(Internal Server Error) and few others.. <errors> <error> An exception occurred while creating the customer</error> <error> blah argument is not valid.</error> </errors> Now i am not sure , whether this is the correct way of sending the errors to the client. Maybe it should be present in the header of the response. I will really appreciate any help. Thanks!

  • Linq to SQL Problem System.Data.Linq.IdentityManager.StandardIdentityManager.MultiKeyManager

    - by luckyluke
    I have a really tricky thing going up here. My project has around 100 tables and they are all mapped by LINQ. Everything works fine in a dev and test environment. These enviroments are MS Win 2008 r2 servers with SQL 2008 sp1 databases. IIS and SQL are on a different machines. Now on production enviroment which is MS Win 2003 x64 web farm + geoclustered SQL 2008 IT DOES not work. All I get is the exception System.IndexOutOfRangeException: Index was outside the bounds of the array. at System.Data.Linq.IdentityManager.StandardIdentityManager.MultiKeyManager3.TryCreateKeyFr>om Values(Object[] values, MultiKey& k) at System.Data.Linq.IdentityManager.StandardIdentityManager.IdentityCache2.Find(Object[] keyValues) at System.Data.Linq.ChangeProcessor.GetOtherItem(MetaAssociation assoc, Object instance) at System.Data.Linq.ChangeProcessor.BuildEdgeMaps() at System.Data.Linq.ChangeProcessor.SubmitChanges(ConflictMode failureMode) at System.Data.Linq.DataContext.SubmitChanges(ConflictMode failureMode) at ERS.IIMP.Services.ExposuresSrv.Update(Int32 ExpID, Int32 AssID) Services\ExposuresSrv.cs` My question is What the hell. They have precisely the same DBML, the DB has exactly THE SAME structure (when I get the DB from prod to TEST and mount it eveything works just great), the binaries on the WEB Server are the same. I seriously do not know what to do.... Did anyone found that Linq works on one env and does not on the second?? I mam really lost here. I really hope You can help me:)

  • C# Taking a element off each time (stack)

    - by Sef
    Greetings, Have a question considering a program that stimulates a stack.(not using any build in stack features or any such) stack2= 1 2 3 4 5 //single dimension array of 5 elements By calling up a method "pop" the stack should look like the following: Basically taking a element off each time the stack is being "called" up again. stack2= 1 2 3 4 0 stack2= 1 2 3 0 0 stack2= 1 2 0 0 0 stack2= 1 0 0 0 0 stack2= 0 0 0 0 0 - for (int i = 1; i <= 6; i++) { number= TryPop(s2); //use number ShowStack(s2, "s2"); } Basically I already have code that fills my array with values (trough a push method). The pop method should basically take the last value and place it on 0. Then calls up the next stack and place the following on 0 (like shown above in stack2). The current pop method that keeps track of the top index (0 elements = 0 top, 1 element = 1 top etc..). Already includes a underflow warning if this goes on 0 or below (which is correct). public int Pop() { if(top <= 0) { throw new Exception("Stack underflow..."); } else { for (int j = tabel.Length - 1; j >= 0; j--) { //...Really not sure what to do here. } } return number; }/*Pop*/ Since in the other class I already have a loop (for loop shown above) that simulates 6 times the s2 stack. (first stack: 1 2 3 4 0, second stack 1 2 3 0 0 and so on.) How exactly do I take a element off each time? Either I have the entire display on 0 or the 0 in the wrong places / out of index errors. Thanks in advance!

  • In Java, send commands to another command-line program

    - by bradvido
    I am using Java on Windows XP and want to be able to send commands to another program such as telnet. I do not want to simply execute another program. I want to execute it, and then send it a sequence of commands once it's running. Here's my code of what I want to do, but it does not work: (If you uncomment and change the command to "cmd" it works as expected. Please help.) try { Runtime rt = Runtime.getRuntime(); String command = "telnet"; //command = "cmd"; Process pr = rt.exec(command); BufferedReader processOutput = new BufferedReader(new InputStreamReader(pr.getInputStream())); BufferedWriter processInput = new BufferedWriter(new OutputStreamWriter(pr.getOutputStream())); String commandToSend = "open localhost\n"; //commandToSend = "dir\n" + "exit\n"; processInput.write(commandToSend); processInput.flush(); int lineCounter = 0; while(true) { String line = processOutput.readLine(); if(line == null) break; System.out.println(++lineCounter + ": " + line); } processInput.close(); processOutput.close(); pr.waitFor(); } catch(Exception x) { x.printStackTrace(); }

  • WCF Callback Faulted - what happens to the session?

    - by RemotecUk
    Just trying to get my head around what can happen when things go wrong with WCF. I have an implementation of my service contract declared with an InstanceContextMode of PerSession... [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Multiple)] The calls happen as follows: My client calls the server and calls GetServerUTC() to return the current UTC time of the server. This is a one way call and the server will call the client back when its ready (trivial in this instance to simply return the current time!) The server calls back to the client and for test purposes in the callback implementation on the client I throw an exception. This goes unhandled in the client (for test purposes) and the client crashes and closes down. On the server I handle the faulted event handler on the ICommunicationObject... obj.Faulted += new EventHandler(EventService_Faulted); Questions... Will this kill off the session for the current connection on the server. I presume I am free to do what I want in this method e.g. logging or something, but should I do anything specific here to terminate the session or will WCF handle this? From a best practise view point what should I do when the callback is faulted? Does it mean "something has happened in your client" and thats the end of that or is there something I a missing here? Additionally, are there any other faulted handlers I should be handling. Ive done a lot of reading on WCF and it seems sort of vague on what to do when something goes wrong. At present I am implementing a State Machine on my client which will manage the connection and determine if a user action can happen dependant on if a connection exists to the server - or is this overkill. Any tips would be really appreciated ;)

  • What type of things can cause sgen msbuild task to fail intermittantly with Access Violation?

    - by Mark Allanson
    In our MSBuild file for our project we sgen an assembly containing classes used during xml serialization. The classes are generated via xsd.exe. We use the following SGen task configuration. <SGen ToolPath="$(SdkPath)" ShouldGenerateSerializer="true" UseProxyTypes="false" BuildAssemblyName="AssemblyName.dll" BuildAssemblyPath="Outputs" ContinueOnError="false" /> Intermittantly the following error is thrown when executing the msbuild script on our build server. Originally this error might have occurred once out of every 50 (CI) builds, recently the frequency has been increasing and it now occurs maybe 5-6 out of every 10 builds. The size of the assembly that is being Sgenned is about 410k (circa 35,000 lines of generated code), and when successfull the serialization assembly is about 1.7M in size. When it fails, the output is as follows: Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. E:\Path_ToBuild_Workspace\SolutionBuild.MSBuild(74,5): error MSB6006: "sgen.exe" exited with code -1073741819. We are using Hudson to manage our builds, so the msbuild and sgen processes are therefore spwaned by the Hudson.exe. There's not much out there on the interwebs regarding this type of error from SGen. Certainly nothing concrete.

Anyone know how to fix it?

  • Red5 Unable to Start Distribution.

    - by Iscariot
    I have installed subclipse, Ant, IvyDE, Red5 Plugin for eclipse, All of the Environmental variables are set and the necessary elements have been added to the path. I am attempting to create a Red5 Distribution by using eclipse, opening Build.xml right clicking dist [default] in the outline window and running as and selecting Ant Builder. Eclipse says that the build is Successful. I first stop the Red5 Service, and then I attempt to run the build I create in eclipse it fails, below are the errors that display in the command prompt. I was hoping someone else might have run into a similar issue before.

  • LINQ-To-SQL and Mapping Table Deletions

    - by Jake
    I have a many-to-many relationship between two tables, let's say Friends and Foods. If a friend likes a food I stick a row into the FriendsFoods table, like this: ID Friend Food 1 'Tom' 'Pizza' FriendsFoods has a Primary Key 'ID', and two non-null foreign keys 'Friend' and 'Food' to the 'Friends' and 'Foods' tables, respectively. Now suppose I have a Friend tom .NET object corresponding to 'Tom', and Tom no longer likes pizza (what is wrong with him?) FriendsFoods ff = tblFriendsFoods.Where(x => x.Friend.Name == 'Tom' && x.Food.Name == 'Pizza').Single(); tom.FriendsFoods.Remove(ff); pizza.FriendsFoods.Remove(ff); If I try to SubmitChanges() on the DataContext, I get an exception because it attempts to insert a null into the Friend and Food columns in the FriendsFoods table. I'm sure I can put together some kind of convoluted logic to track changes to the FriendsFoods table, intercept SubmitChanges() calls, etc to try and get this to work the way I want, but is there a nice, clean way to remove a Many-To-Many relationship with LINQ-To-SQL?

  • Python with Wiimote using pywiiuse module

    - by Anon
    After seeing the abilities and hackibility of wiimotes I really want to use it in my 'Intro to programming' final. Everyone must make a python program and present it to the class. I want to make a game with pygame incorporating a wiimote. I found pywiiuse which is a very basic wrapper for the wiiuse library using c types. I can NOT get anything beyond LEDs and vibrating to work. Buttons, IR, motion sensing, nothing. I've tried different versions of wiiuse, pywiiuse, even python. I can't even get the examples that came with it to run. Here's the code I made as a simple test. I copied some of the example C++ code. from pywiiuse import * from time import sleep #Init wiimotes = wiiuse_init() #Find and start the wiimote found = wiiuse_find(wiimotes,1,5) #Make the variable wiimote to the first wiimote init() found wiimote = wiimotes.contents #Set Leds wiiuse_set_leds(wiimote,WIIMOTE_LED_1) #Rumble for 1 second wiiuse_rumble(wiimote,1) sleep(1) wiiuse_rumble(wiimote,0) #Turn motion sensing on(supposedly) wiiuse_motion_sensing(wiimote,1) while 1: #Poll the wiimotes to get the status like pitch or roll if(wiiuse_poll(wiimote,1)): print 'EVENT' And here's the output when I run it. wiiuse version 0.9 wiiuse api version 8 [INFO] Found wiimote [assigned wiimote id 1]. EVENT EVENT Traceback (most recent call last): File "C:\Documents and Settings\Nick\Desktop\wiimotetext.py", line 26, in <mod ule> if(wiiuse_poll(wiimote,1)): WindowsError: exception: access violation reading 0x00000004 It seems each time I run it, it prints out EVENT 2-5 times until the trace back. I have no clue what to do at this point, I've been trying for the past two days to get it working. Thanks!

  • Bitrate Switching in xml playlist not loading video

    - by James Williams
    Using JW Player ver 5.4 and JW Embedder. Plugins are grid by Dabbler and fbit (Facebook). The Bitrate switching is not working. Does work fine for one video with HTML5 Video tag. When more than one video, it only shows the first video pic. Works fine with no bitrate switching. Code - HTML5 <script type="text/javascript" src="jwplayer/jwplayer.js"></script> <video id="container"></div> <script type="text/javascript"> jwplayer("container").setup({ flashplayer: "jwplayer/player.swf", streamer: "rtmp://server/location/", playlistfile: "playlists/playlist.xml", plugins: { grid: { rows: 4, distance: 60, horizontalmargin: 75, verticalmargin: 75 }, fbit: { link: "http://www.domain.com" } }, height: 375, width: 850, dock: true }); </script> XML - ATOM/MEDIA xmlns:jwplayer='http://developer.longtailvideo.com/trac/wiki/FlashFormats' Demostration Playlist Video 1 rtmp rtmp://server/location/ Video 2 rtmp rtmp://server/location/ have tried it with both video and div tags for the container. Div tag just shows a blank video area and a Null exception on Line 1 char 1863, this is probably the jwplayer.js file. XML is larger than this, this is to give you a brief syntax of my code and xml. I have searched for over 6 hrs on both longtail and search engine searches. Thank you in advance.
