Ah, my bad, I thought it did. Well, that's not the issue at all, then.
I'm not calling anything (so far as I'm aware :-) that would be
starting any other threads.
It may be that you have inadvertently created two instances of your
controller and are only updating the information in one of them while
the bindings are on the other one.
Now that is something to consider, but I can't see how it's likely...
I'm now in the process of trying to go through all the code to make
sure that somewhere I'm not inadvertently bypassing accessors/etc. I
have a group of buttons that are enabled/disabled based on a BOOL key
in my object that is contained by an NSArrayController. It works fine
for the most part, but there are places where it gets updated and the
UI does not update. I'm definitely using the accessors at that point,
and debugging it shows the ivar has the right value. If I implement my
own KVO on that, I get called, but the UI doesn't update. FRUSTRATING.
If I can simplify it to a test case, I'll find a place to stash the
code for review. Otherwise, I have nothing to hide (it will be a free
release anyway) and would post the project for anyone willing to spend
a bit of time looking at it.
Thanks!
Steve
