Bug 387528

Description Alexander Gurov 2012-08-18 04:48:44 EDT

What steps will reproduce the problem?
1. Don't know, just used few double clicks in Synchronize View, then closed the compare editor.

After that NPE occurs every time I open a file in the workspace. When NPE occurs editor content becomes blank and I can't edit the file until I click on some file in package explorer. Very bothersome issue.
