Thank you for your comment.
Did you really manage to create *editable* view-based table views with data sources?
Then I am curious to know how you managed to make them editable.
A data source method channeling data from the table view to the data source is nowhere to be seen.
- (void)tableView:(NSTableView *)tableView setObjectValue:(id)object forTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row
does not seem to be called.
I have a view based table view working with a data source. But it is not (yet) editable.
The only thing I can imagine is to catch textDidEndEditing in a delegate from the field editor and get the value via editedRow and editedColumn or something similar.
But this is rather awkward.
I wonder why there is nothing relevant in the docs, no example on the web...
