Hello,
To determine what's going on I'll need to know which volume release for WPF you are using. Eg. 15.2 and the root cause of the issue. A sample and steps to reproduce the behavior would also be of some help to determine the issue.
That's just it, it's hard to reproduce and we have a user who is getting this error sporadically. I just need a general idea of what to look for to try and reproduce it. If you could just give me some ideas of what might cause this issue that's what I'm looking for. It's version 13.1.20131.2336. It's happening when we select field chooser to add a field, as soon as we add a field it is throwing this error.
I have created case for you with ID CAS-169592-Y0M6K4. You could reach your case following the link bellow:
https://www.infragistics.com/my-account/support-activity I've already responded via the mentioned case, so if you have any further questions or comments please update me there.
The fix for development issue 213827 which was logged for this issue is available in the latest service release which can be downloaded from the My Keys and Downloads page.
