Eric, +1?  This is a surgical fix for the steps as given by Remy.  Do you think we can run into similar cases, but with other controls being disposed earlier than we expect?

Comment 3 Boris Bokowski

Susan, +1 for RC3?

I have seen this exception logged in other cases in the past but didn't investigate deep enough for reproducible steps.

> Susan, +1 for RC3?

+1 for RC3. 
The fix is low risk and definitely an improvement, although I agree with Remy that there are likely more bugs like these.

I wonder if we should also check whether
tpl.clientArea.isDisposed()

If the toolbar and tpl client area are siblings (and I think they are?), then depending on platform and disposal order, it is theoretically possible that at some moment in time the TB had not been disposed yet but the composite already had.

Comment 6 Eric Moffatt

2010-07-21 17:49:58 EDT

looks good, this is gone with my current patch but i won't make the build with the real one tonight...I'll merge it in tomorrow.

Comment 7 Boris Bokowski

2010-07-21 17:51:12 EDT

committed to HEAD.

Comment 8 Boris Bokowski

2010-07-21 17:52:16 EDT

Eric is working on a better fix. The reason for doing this point fix is to hopeefully get less duplicate bugs being filed tomorrow when we test drive the new DND code.

Comment 10 Susan McCourt

2010-07-22 12:46:43 EDT

Build id: I20100721-2056.
Win7.

I installed the e4 tools and was prompted for restart.  While it was trying to restart I saw the familiar stack.  Prior to installing the tools, I had been using the build for awhile, and had done some D&D or perspective stuff (in the course of working, not trying to break anything).  So I can't say for sure what got me in this state...

I wasn't sure whether to open a new bug or use this bug to track the problem.  We all realize/suspect that there are other cases besides the surgical fix where this can happen....

Comment 12 Eric Moffatt

2010-07-27 14:19:27 EDT

I can't repro this on I20100726-2152. Susan, after starting fresh have you been able to see this again?

Comment 13 Susan McCourt

2010-07-27 15:20:02 EDT

I started with today's build, cleaned my deltas, worked for awhile.  During this time I synched CVS, stuck the problems view in the editor area, maximized it, put it back.  Dragged outline view to its own window, then back, etc.

Everything fine.
Then I went to install the model tooling, and sure enough, get the error as the platform tries to shutdown/restart.
