[Pyobjc-dev] problems building editable tableviews

[Aaron S. <me...@aa...>]

Hi there,

I've got a PyObjC app that has a table view working great, but as soon 
as I add a definition for tableView_setObjectValue_forTableColumn_row_, 
my app crashes as soon as try to edit one of the rows and before my 
Python function gets called. Here's the stacktrace:

Thanks for any help you can provide.

Also, what's the policy on threading? I expect my app to do some 
intense networking and indexing, and I don't want it to become 
unresponsive while it's doing that. I tried importing "threading", but 
when I tried to do something in another thread, it spewed out thousands 
of no autoreleasepool -- leaking! messages.

Thanks again for such an awesome tool!
