Hello,
I wasn't sure where to put this topic so please move if you need to.
I've updated to 13.1 (including the latest service release) and I've been seeing this in my application more and more (I'm not able to provide a sample project at the moment due to deadlines).
Can anyone think why this might be? The latest sample is where I'm simply trying to show a form. I also see this sometimes when the application starts up in the splash screen (even if I add exception handling around this it gets thrown as an unhandled exception regardless which makes me think it's an internal issue):
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.************** Exception Text **************System.NullReferenceException: Object reference not set to an instance of an object. at Infragistics.Win.Misc.UltraButton.OnLostFocus(EventArgs e) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
Thanks,Andrew
Hello Andrew,
I have logged a development issue for this.
You can view the status of the development issue connected to this case by selecting the "Development Issues" tab when viewing your active cases on the web site.
Hi Michael,
Apparently my case has been closed however it says the following under development issues "There are no development issues associated with this support request."
Can you provide me with screenshots without exposing any of your information of where says "There are no development issues associated with this support request." ?
I closed the non-thread case and kept this forum case open, since there were two. I linked the development issue to this forum case in our systems. I currently see this case in development, and you should as well.
Please let me know if you have any additional questions.
Be useful to be able to look bugs up - I don't seem to be able to find a searchable area..
In this instance the bug also seems to exist in v12.1 : 12.1.20121.2135 but it does not exist in 12.1.20121.1001
So how do I find exactly when this bug was introduced if I can't look up details..?
Try hotfix 13.1.20131.2040
This issue was resolved in versions 12.2, 13.1. NetAdvantage for Winforms 2012 Volume 1 is now expired. For more information please visit our product lifecycle page.
