UltraButton.OnLostFocus - System.NullReferenceException: Object reference not set to an instance of an object.
posted

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.

Thanks,
Andrew
