Hi,
I have a window with a drawer. The drawer only contains an
NSOutlineView which controls the contents of the window, sort of like
the Mailbox-Drawer in Mail.app. Everything works exactly like I want...
until I close the window. Sometimes it crashes and I have no idea why
it should. I'm reasonably certain I haven't over- or underreleased any
objects. Excerpts from the call stack:
#0 0x9001b52c in kill
#1 0x9005ceec in abort
#2 0x90688da4 in _objc_error
#3 0x90688d30 in __objc_error
#4 0x930a0534 in -[NSTableView drawRow:clipRect:]
#5 0x93140a68 in -[NSOutlineView drawRow:clipRect:]

#7 0x930809ec in -[NSView _drawRect:clip:]
#8 0x930763b0 in -[NSView

The only Outlineview I am using is the one in the drawer, so that's
where I should look for the bug. In the stack there is a call
"GetKeyboardFocus" which got me thinking maybe the outlineview still is
registered as being first responder? I tried closing the window after
first clicking anywhere in the window, so the outlineview isn't first
responder anymore: No crashes. Not conclusive, since it doesn't always
crash, but maybe a hint?
I tried in the WindowControllers windowWillClose-Notification to close
the drawer first or make it release it's firstResponder-Status by
calling [[self window] makeFirstResponder:nil]... No change, still
crashes.
Any ideas where I could look? Any known bugs in that area?
