  • EF Code First Detached Entity not updating object reference

    - by Alvaro
    I'm posting the exact entity: public class Person : ContactableEntity { public Plan Plan { get; set; } public int Record { get; set; } public int PersonTypeValue { get; set; } } I'm using the following code to update in a disconected context fashion: public void Update(DbSet MySet, object Obj) { MySet.Attach(Obj); var Entry = this.Entry(Obj); Entry.State = EntityState.Modified; this.SaveChanges(); } This is a method exposed by my dbContext Called this way: PersistentManager.Update(PersistentManager.Personas,UpdatedPersona); The problem is, EF will update any property but the referenced Plan object. Can someone tell me where is the mistake? In advance : the entity reaches the point of update with all the properties correctly set. EF just fails to update the FK in the Database (no exception though)

  • Asynchronous Processing in JBoss 6 ("Comet")

    - by chris_l
    edit: Retagged as tomcat, since this is really a question about the Tomcat embedded inside JBoss 6, rather than JBoss itself I have an extremely simple servlet, which works on Glassfish v3. It uses Servlet 3.0 Asynchronous Processing. Here's a simplified version (which doesn't do much): @WebServlet(asyncSupported=true) public class SimpleServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { final AsyncContext ac = request.startAsync(); ac.setTimeout(3000); } } On JBoss 6.0.0 (Milestone 2), I get the following Exception: java.lang.IllegalStateException: The servlet or filters that are being used by this request do not support async operation at org.apache.catalina.connector.Request.startAsync(Request.java:3096) at org.apache.catalina.connector.Request.startAsync(Request.java:3090) at org.apache.catalina.connector.RequestFacade.startAsync(RequestFacade.java:990) at playcomet.SimpleServlet.doGet(SimpleServlet.java:18) at javax.servlet.http.HttpServlet.service(HttpServlet.java:734) ... Do I have to do anything special to enable Asynchronous Processing in JBoss 6? Or do I need an additional deployment descriptor? ...

  • Bad temperature sensors on Foxconn motherboard?

    - by Gawain
    I have a system with a Foxconn V400 series motherboard and AMD Athlon 3000+ processor. Ever since I got it a few years ago the fans (particularly the CPU fan) have been really loud. So recently I installed SpeedFan to see why they were running so fast. SpeedFan reported the CPU temperature to be 32C, and one motherboard sensor at about 26C. But the other two motherboard sensors were reporting 78C and 64C respectively. Naturally the fans were both maxed out because of this, with the CPU fan at 5800rpm and the case fan at 2400rpm. I opened the case and everything inside was literally cool to the touch, with the exception of the CPU heatsink which was slightly warm, but nowhere near 78C. It seems like the temperature sensors are either defective or being read incorrectly. Is there some way I can decrease my fan noise without risking damage to my processor? Some way to ignore those two temp sensors? Any help would be greatly appreciated.

  • How to pause a thread in java?

    - by mithun1538
    Consider the following code: while(true) { someFunction(); Thread.sleep(1000); } What I want is that, someFunction() be called once every 10 seconds. But this is not the case. It is being called every second. I tried Thread.wait(1000), but even that doesnt help. I removed of the while part, just kept the body, and at the end wrote : Thread.start(); But it throwed an exception. Is there any other solution to this?

  • Can't set background colour for UIView from ViewController

    - by Curyous
    I have the following code in the view controller: - (void)viewDidLoad { [super viewDidLoad]; ThemeManager *themer = [ThemeManager sharedInstance]; UIView *theView = self.view; UIColor *forBackground = [themer backgroundColour]; [theView setBackgroundColor:forBackground]; } but when execution gets to the setBackgroundColor line, I get the following error: *** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFNumber CGColor]: unrecognized selector sent to instance 0x1237c40' There's got to be something simple that I'm doing wrong, how do I set the background colour? Do I have to subclass the view and do it in there? I'd prefer not to have the extra class, even though that is better separation of the whole model/view/controller thing. Update: value returned by [themer backgroundColour] is constructed using colorWithPatternImage:, could this make a difference?

  • UILocalNotification crash

    - by Miky Mike
    Hi everyone, could you please help me ? I'm setting up an UILocalNotification and It crashes when I try to set its userInfo dictionary. My dictionary is not empty (It contains 88 objects). Here is the code : NSDictionary* myUserInfo = [NSDictionary dictionaryWithObject: fetchedObjects forKey: @"textbody"]; UILocalNotification *localNotif = [[UILocalNotification alloc] init]; if (localNotif == nil) return; // défining the interval NSTimeInterval oneMinute = 60; localNotif.timeZone = [NSTimeZone localTimeZone]; NSDate *fireDate = [[NSDate alloc]initWithTimeIntervalSinceNow:oneMinute]; localNotif.fireDate = fireDate; localNotif.userInfo = myUserInfo; [fetchedObjects release]; and the console gives me this : Property list invalid for format: 200 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'unable to serialize userInfo: (null)' Any idea ?

  • Exchange 2003 Public Folder Replica list

    - by Niall
    Hi, I am trying to update a replica list on a Exchange 2003 public folder. I am using the WMI namespace exchange_publicfolder to try and add an Exchange server (using the servers DN) to the AddReplica procedure. Every time I run this I get an invalid parameter as an exception. Below is the code that I am using to do this. WMI.Connect(Server, credentials) Using WMISearcher As New ManagementObjectSearcher(WMI.Scope, & _ New ObjectQuery(String.Format("SELECT * FROM Exchange_Publicfolder WHERE path='{0}'", Name))) Using PublicFolder As ManagementObjectCollection = WMISearcher.Get For Each Folder As ManagementObject In PublicFolder Dim BaseFolder As ManagementBaseObject = Folder.GetMethodParameters("AddReplica") BaseFolder("path") = ServerDN Folder.InvokeMethod("AddReplica", BaseFolder, Nothing) Next End Using End Using I have used WMI before and I can see that the call is connecting to the correct public folder because i can itterate through the properies once the query has executed. I am not sure what I am doing wrong here. If anyone has any ideas or comments the please let me know. Thanks Niall

  • 'System.Windows.Data.MultiBinding' is not a valid value for property 'Text'.

    - by chaiguy
    I'm trying to write a custom MarkupExtension that allows me to use my own mechanisms for defining a binding, however when I attempt to return a MultiBinding from my MarkupExtension I get the above exception. I have: <TextBlock Text="{my:CustomMarkup ...}" /> CustomMarkup returns a MultiBinding, but apparently Text doesn't like being set to a MultiBinding. How come it works when I say: <TextBlock> <TextBlock.Text> <MultiBinding ... /> </TextBlock.Text> </TextBlock> But it doesn't work the way I'm doing it?

  • Rendering a view to a string in ASP.NET MVC 2

    - by Frank Rosario
    We need to render an ActionResult to a string to add pages to our internal search engine index. We settled on this solution to render to string. I've run into a problem with the ExecuteResult call used to process the View. Code Snippet: var oldController = controllerContext.RouteData.Values["controller"]; controllerContext.RouteData.Values["controller"] = typeof(TController).Name.Replace("Controller", ""); viewResult.ExecuteResult(controllerContext); // this line breaks I receive the following error: "Object reference not set to instance of object" error. I've confirmed viewResult is not null, so the exception has to be thrown internally in ExecuteResult. What could we be missing?

  • Writing out BMP files with DataBuffer.TYPE_FLOAT or DataBuffer.TYPE_DOUBLE in java

    - by Basil Dsouza
    Hi Guys, I had a problem working with the image classes in java. I am creating a buffered image with DataBuffer.TYPE_DOUBLE. This all works fine in memory (I think). But the problem starts when I try to write it using ImageIO.write. Initially I was getting no exception at all and instead was only getting an empty output file for my troubles.. After a bit of poking around in the code, i found out that the bmp writer doesnt support writing type_double type of files. From: BMPImageWriterSpi.canEncodeImage: if (dataType < DataBuffer.TYPE_BYTE || dataType > DataBuffer.TYPE_INT) return false; So my question is, does anyone have a way of writing out those kind of images to disk? any documentation or tutorial, or link would be helpful. Thanks, Basil Dsouza

  • MOSS Faceted Search 3.0

    - by nav
    Hi, Has anyone installed Faceted Search v3.0 for MOSS working with date columns? When I map a column of DateTime type and click the Search BreadCrumb webpart "remove filter" link (next to the edit filter link) an exception is thrown. The search Breadcrumb webpart throws an error when I click the "Remove filter" link (this is the one represented by the broken link icon - next to the "Edit facet" icon). This seems to only occur after clicking the "Remove filter" link for Facets of DateTime type after which it occurs on every instance for all Facets. The error thrown is posted here: http://facetedsearch.codeplex.com/Thread/View.aspx?ThreadId=213398 Many Thanks, Nav

  • Can a grails controller extend from a base class? How to make it so grails doesn't blow up?

    - by egervari
    I wrote a base class to help build my controllers more quickly and to remove duplication. It provides some helper methods, default actions and some meta programming to make these things easier to build. One of those methods in the base class is like this: def dynamicList(Class clazz) { def model = new LinkedHashMap() model[getMapString(clazz) + "s"] = list(clazz) model[getMapString(clazz) + "sTotal"] = count(clazz) model } The action that calls it, also in the base class, is this: def list = { dynamicList(clazz) } Unfortunately, when I go to list action in the controller subclass that inherits the base class when my application is deployed, I get this exception: groovy.lang.MissingMethodException: No signature of method: groovy.lang.MissingMethodException.dynamicList() is applicable for argument types: (java.lang.Class) values: [class project .user.User] at project.user.UserController$_closure1.doCall(UserController.groovy:18) at project.user.UserController$_closure1.doCall(UserController.groovy) at java.lang.Thread.run(Thread.java:619) How can I hit grails over the head and just tell it do what I want it to do? My controller unit tests run just fine, so grails' run-time is totally at fault :/ Ken

  • T4MVC calling controller methods multiple times?

    - by Maslow
    I suspected there was some hidden magic somewhere that stopped what looks like actual method calls all over the place in T4MVC. Then I had a view fail to compile, and the stackTrace went into my actual method, not the generated code in T4MVC. <%=Ajax.ActionLink("Apply", "Apply", new RouteValueDictionary() { { "shortName", item.Shortname } }, new AjaxOptions() { UpdateTargetId = "masterstatus" })%> <%=Html.ActionLink("Apply",MVC.Alliance.Apply(item.Shortname),new AjaxOptions() { UpdateTargetId = "masterstatus" }) %> The second method threw an exception on compile because the method Apply in my controller has an [Authorize] attribute so that if someone that isn't logged on clicks this, they get redirected to login, then right back to this page. There they can click on apply again, this time being logged in. And yes I realize one is Ajax.ActionLink while the other is Html.ActionLink I did try them both with the T4MVC version. Is this a fluke or is it actually calling into the real methods and running my database calling code just to generate the views?

  • EF problem with entity re-ordering and uniqueness constraint

    - by wpfwannabe
    I am using Entity Framework and I've come to an interesting stumbling block. Let's say there is a db table "Item" with "sequence" column of type int (and others of course). Column "sequence" must be unique and it is used for (re)ordering of items. EF maps this table to "Item" class with "sequence" int property. Now let's say I want to swap position of two items by mutually exchanging each other's sequence number. Upon calling SaveChanges() EF throws an exception complaining about "sequence" uniqueness. It probably generates two UPDATEs and the first one probably fails. I assume that plain SQL solution to this issue is using a third UPDATE to introduce a unique sequence value in the process but I am stuck with EF. Any thoughts?

  • Is there any way to limit the size of an STL Map?

    - by Nathan Fellman
    I want to implement some sort of lookup table in C++ that will act as a cache. It is meant to emulate a piece of hardware I'm simulating. The keys are non-integer, so I'm guessing a hash is in order. I have no intention of inventing the wheel so I intend to use stl::map for this (though suggestions for alternatives are welcome). The question is, is there any way to limit the size of the hash to emulate the fact that my hardware is of finite size? I'd expect the hash's insert method to return an error message or throw an exception if the limit is reached. If there is no such way, I'll simply check its size before trying to insert, but that seems like an inelegant way to do it.

  • Creating share programmatically fails with error 9

I am passing a string and have tried to use an explicit string and I still get error 9. I am creating the share remotely rather than on local machine however. Not sure if that matter.

  • What happens to an ActiveX control (COleControl) after the call to OnDestroy() ?

    - by richj
    I have an ActiveX control written in C++ that runs in Internet Explorer 8. Most of the time (approx 90%) when the tab or browser containing the control is closed, there is an access violation like this: The thread 'Win32 Thread' (0x1bf0) has exited with code 0 (0x0). Unhandled exception at 0x77b3b9fd in iexplore.exe: 0xC0000005: Access violation reading location 0x65007408. The access violation occurs after the call to OnDestroy() but before the call to the control's destructor. The debug output says: No symbols are loaded for any call stack frame. The source code cannot be displayed. None of my code is present in the stacktrace, although perhaps the heap was corrupted at some earlier point during execution. What lifecycle events does an ActiveX control receive between the call to OnDestroy() and the control's destructor?

  • How to get this XmlAttribute

    From the MusicBrainz REST service, I get the following xml: <artist-list offset="0" count="59"> <artist type="Person" id="xxxxx" ext:score="100"> ... Using WCF and XmlSerializationFormat, I'm able to get the type and id attributes... but How do I get the "ext:score" one? This works: public class Artist { [XmlAttribute("id")] public string ID { get; set; } [XmlAttribute("type")] public ArtistType Type { get; set; } But this doesnt: [XmlAttribute("ext:score")] public string Score { get; set; } It produces a serialization exception. I've also tried just using "score", but it doesn't work. Any help?
