Description Paul Webster CLA 2010-05-26 10:06:10 EDT
I had my class, ContextMenuView open along with some others.  I used Close Others from CTRL+3.  It close all but 4 of my open editors (including ContextMenuView, which was the active editor and *shouldn't* have been closed).

Now I can no longer open an editor on that file.  Open Type simply does nothing.  But double-clicking in the package explorer generates this error:

Comment 1 Eclipse Genie CLA 2019-04-17 05:27:27 EDT
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.
