Description Mikhail Matveev 2007-02-21 15:40:16 UTC 
I created LoanApplication schema and left IDE open for several hours. After
return, I got following exception.
Functionality wasn't affected.

I guess it's probably not anything easily reproducible?
Comment 2 Miloslav Metelka 2007-03-27 13:09:04 UTC 
It seems that the action map of the text component is null. I've made the code
to check for that.

Checking in NbEditorUI.java;
