Bug 360869

Description Deepak Azad 2011-10-13 12:41:24 EDT

Eclipse 4.2 - I20111007-1625 and EGit - 1.2.0.201110091909

- Enable Find toolbar in History view
- Close History view
- From Git Repositories view open history on an repository
=> History view opens and the Next and Previous buttons of the toolbar are enabled. But they should be disabled at this point at the text field is empty.

In this state clicking one of the buttons will cause the following exception. Once I enter some text and then delete it, the enablement of buttons works fine.

java.lang.ArrayIndexOutOfBoundsException: Array index out of range: -1
