Re: populate a custom sub-class with data from bindings - SOLVED

The answer in my case was to first impliment some NSOutlineView
extenssions so that I could actually access the objects stored in the
tree. These can be found at:

http://homepage.mac.com/matthol2/cocoa/page2/page2.html

Then I implemented the NSOutlineView delegate method

- (void)outlineView:(NSOutlineView *)outlineView
willDisplayCell:(id)cell forTableColumn:(NSTableColumn *)tableColumn
item:(id)item

to update the values in the custom cell from the data in my item.
