NullPointerException when opening editor

Report · Oct 18, 2010

Hello

Not sure if this is a known bug.. I had just opened FB this morning, and clicked the editor tab for a file (which was still there from my last session). Instead of seeing the editor, I got this exception:

Hi,

Was the project closed or deleted before you opened editor? Can you provide more details to reproduce the problem?

The project was not closed. I had just started my PC, opened FB and encountered the problem. Other editors failed to open as well.

I then closed FB, opened it again and the bug did not appear again.
