Blair,
I can't reproduce this one at will, but, it happened four times today, twice
when I was actively trying to make it happen. It has something to do with
cutting a view in the VC. In particular, I was trying to remove a card from
a card container, and I _think_ that's been the case each time it's
happened.
On the most recent occurance, I used the debugger to trace the parent
presenter heirarchy to the the PAI in the VC (I was expecting to be lead to
the view hierarchy). It's looking for a view by arrangement. It might be
race condition that usually ends the one would like; perhaps a deferred
action that sometimes gets processed too late?? I recently fixed a bug in
one of my apps that turned out to be caused by modifying a collection while
iterating it; it was also somewhat difficult to reproduce until we hit just
the right sequence of operations.
Have a good one,
Bill
