Using IWorkbenchPage#hideEditor to confine editor to a single perspective [message #499322]

I noticed the new API in 3.5 and I think it can help me fix a bug in my RCP
application. My use case confines editors to a single perspective (the
others just contain views). However, if I have open editors in the editor
perspective and switch to a non-editor perspective, I still see the editor
contributions to the toolbar and menus. I added an IPerspectiveListener to
"hide" all the editors when the editing perspective is deactivated, and
"show" them when it is activated. Two problems I've encountered:

1. Toolbar contributions always seem to be removed, but sometimes (not
always) the File menu still has Close and Close All enabled
2. When I return to the editor perspective, the "active" editor is always
the first editor instead of the one that was active when I left

Is this the right approach? Any suggestions on the above two issues?

Thanks
Will

#1 is probably a bug. If hiding the last editor doesn't set the system to have no active editor, then I could see that happening.

#2 you would have to remember the editor that was active, and then after you've added them all back call IWorkbenchPage#bringToTop(IWorkbenchPart). The hideEditor/showEditor works by doing almost all of a close and an open, but that effects the MRU list and the activation list.

Thanks Paul. I filed a bug for #1 with a test case
http://bugs.eclipse.org/296600 Sorry for the delay - I wanted to test on
3.5.1 and create a reproducible test case.

Your suggestion for #2 works.
