Description Boris Bokowski

I edited in the compare editor and ended up in this weird state (screenshot to follow). Found this stack trace in my .log six times:

Oh, I had a Java editor open on the same file, and it ended up in a weird state too.

BTW, there was no real change where the compare editor showed a change.

I don't have time to try to reproduce this right now, but we can try tomorrow.

If both the Compare editor and Java editor where showing the behavior, then it sounds like a potential problem in the file buffer. Moving to Platform/Text for comment.
