I was hoping these changes would do it ... but unfortunately, I'm still
getting nothing ....
You'll notice the logging below - I can confirm that the address of and
object *selected* is the exact same address of and object I am *reloading*.
Furthermore, the description logging from outlineViewSelectionDidChange:
prints out the old text and the description logging from
reloadSelectedIssue prints out the new text.
Unfortunately, outlineView:viewForTableColumn: is never invoked.
Thanks for the extended help Quincey,
-Luther
- (BOOL)outlineView:(NSOutlineView *)outlineView
isItemExpandable:(id<PVOutlineViewItem>)item {
return (item == nil);
}
- (void)outlineViewSelectionDidChange:(NSNotification *)notification {
NSOutlineView *outlineView = notification.object;
NSInteger selectedRow = outlineView.selectedRow;
_selectedItem = [outlineView itemAtRow:selectedRow];
NSLog(@"selected item:(%@)", self.selectedItem);
}
- (void)reloadSelectedIssue {
NSLog(@"reload selected item: %@", _selectedItem);
[_outlineView reloadItem:_selectedItem reloadChildren:YES];
}
