Hello,
I updated the wpf dlls today to 15.1 from 14.1, but I'm getting an error when I'm opening the windows.
Message: "Object reference not set to an instance of an object."
Source: "InfragisticsWPF4.Controls.Editors.XamComboEditor.v15.1"
StackTrace:
em Infragistics.Controls.Editors.ComboEditorBase`2.XamWebComboEditor_Loaded(Object sender, RoutedEventArgs e) em System.Windows.EventRoute.InvokeHandlersImpl(Object source, RoutedEventArgs args, Boolean reRaised) em System.Windows.UIElement.RaiseEventImpl(DependencyObject sender, RoutedEventArgs args) em System.Windows.BroadcastEventHelper.BroadcastEvent(DependencyObject root, RoutedEvent routedEvent) em System.Windows.BroadcastEventHelper.BroadcastLoadedEvent(Object root) em MS.Internal.LoadedOrUnloadedOperation.DoWork() em System.Windows.Media.MediaContext.FireLoadedPendingCallbacks() em System.Windows.Media.MediaContext.FireInvokeOnRenderCallbacks() em System.Windows.Media.MediaContext.RenderMessageHandlerCore(Object resizedCompositionTarget) em System.Windows.Media.MediaContext.RenderMessageHandler(Object resizedCompositionTarget) em System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Int32 numArgs) em System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Int32 numArgs, Delegate catchHandler)
How can I fix the error?
Thanks
I was just about to post the exact same error as I'm having this issue also.
For me I noticed the problem only seems to appear when the combo is in a tab control and not in the first tab
Strange.. Hope there will be a fix for this soon as I'm close to a deadline!
Thank you for your post.
I have been looking into it. I created a sample application based on your scenario. I tested it with RTM of 15.1 version 1000 and the latest Service Release of 15.1 - version 2008 and I could not managed to reproduce the behavior that you have described. If you are not able to reproduce the issue with the attached sample application, would you please modify it with the functionality, that you are using, so it reproduces the issue. This way I would be able to further investigate this for you and provide you with more detailed information on this matter.
Looking forward to hearing from you.
Hi,
I have attached a sample of the error. I'm not using 15.1 though, it's 14.1 but the newest build
<TabControl> <TabItem Header="First"> <ig:XamComboEditor Width="75" Height="25" /> <TabItem>
<TabItem Header="Second">
<ig:XamComboEditor Width="75" Height="25" />
</TabItem>
</TabControl>
In the main window you will see the following code,
if the combo box in the second tab is commented out it works fine
Hopefully this can be fixed soon as I need to demo my app very soon
Thanks,
FYI, I have also upgraded to 15.1 in the hope it would fix the issue. But still no luck..
I can reproduce this even with your testproject and latest service release (15.1.20151.2008).
I have logged this behavior with our developers in our tracking system, with an issue ID of 192430. I have also created a support ticket on your behalf with number CAS-154396-G5Z3V9 in order to link the development issue to it so that you are automatically updated when a Service Release containing your fix is available for download.
It seems you didn't include me in this. I would like to be notified when it's fixed so I can get the latest service release to fix the bug also.
Please may you replicate it for my account also
Thanks, Grant
