Morning My NSOutlineView binds its NSTableColumn instances to NSTextFieldCells using NSValueBinding.
Some cells are required to contain NSPopUpButtonCell instances so the cell type is manipulated in - outlineView:dataCellForTableColumn:item: NSPopUpButtonCell doesn't support value binding so the normal target->action approach is adopted to update the model. However it appears that the binding machinery causes the NSPopUpButtonCell selection to be reset after the user has interacted with the control. I therefore have to resync the NSPopUpButtonCell selection to the model in - outlineView:willDisplayCell:forTableColumn:item: Is this expected behaviour using multiple NSCell subclasses or is it bug like? Or should I try and directly bind the NSPopUpButtonCell instance in - outlineView:dataCellForTableColumn:item:? Presumable if a cell doesn't support a particular binding its state should remain unaltered.
