Here is the chain of calls -- although not ostensibly helpful. I have 2
items in my outline view - if I select, edit and then try to reload the
item at index=1.
///////
outlineView:isItemExpandable:
- item=selected item
- returns NO
outlineView:child:item
- item=nil, index=1
- returns the selected item
outlineView:isItemExpandable:
- item=selected item
- returns NO
///////
Done ... the outlineView cellView does not update. I also tried hard-coding
outlineView:isItemExpandable: to always return YES ... but reloading the
selected item then simply ran the very first delegate method and then
stopped.
///////
outlineView:isItemExpandable:
- item=selected item
- returns YES
///////
Thanks,
-Luther
