This happened when I tried to drag a ContentPane from a floating SplitPane group to a tabbed document. That is two ContentPanes were grouped together in a SplitPane. When I attempted to drag one of them out of the SplitPane, I got the crash.
TIA.

Anyone at Infragistics investigating this? Please, I need this issue fixed as soon as possible.
Hello,
Would you post steps to help us reproduce this one as well?
Thank you!
Curtis, let me see if I can provide steps to duplcate this problem without sending my entire project. However, could you please send a copy of the stack trace to your developers to look into this?
Thanks.
Hello Klaus,
I have already submitted this issue to developer support. it can be identified as Case ID: CAS-47568-XTJGL7. They will see what they can do with the information you've provided so far. The most effective way to solve these types of issues is with a reproducible sample. Oftentimes, a crash on a client machine is not easily reproducible on another PC. However, we will do what we can to make sure you get the help you need.
The type of rudimentary information we would need is:
I am also getting the below error while dragging the content pane and using the Infragistics version is InfragisticsWPF4.v11.1.dll

Please let me know if in case any change or tweak to be done in code Or change in theme
Thanks

It would help to know what nullable type is being accessed. When the exception happens go to the Call Stack window and double click on the get_Value line. Then go to the Locals window and see what is the Type of "this".
