Description elena_regs 2011-09-08 12:43:39 UTC

I'm working on application build on top of the NetBeans platform.
The bug happens very rarely and randomly. No specific steps - when drag and drop an item from the palette you get the below exception. After that you are able to repeat the action and add the item successfully.

This bug happened a few times on a QA machine. I wasn't able to reproduce it on my dev machine. We don't use NetBeans 7 for now.

Comment 5 Stanislav Aubrecht 2011-09-12 14:29:27 UTC

should be fixed in issue #197559
