Comment 1 Tomasz Zarna CLA 2011-03-23 13:11:23 EDT 
An excerpt from org.eclipse.team.internal.ccvs.ui.wizards.GenerateDiffFileWizard.OptionsPage.calculatePatchRoot():

IResource[] tempResources = ((GenerateDiffFileWizard)this.getWizard()).resources;

if (tempResources == null)
	return;
if (tempResources.length > 1){
	[...]
} else {
	[...]
	IPath fullPath = tempResources[0].getFullPath();
	[...]
}

Apparently, tempResources is an empty array, but we're not prepared for that.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

If the bug is still relevant please remove the stalebug whiteboard tag.
