Two NSTableViews acting as one

Subject: Two NSTableViews acting as one

In the UI for the next release of my app, I have a space that appears to be one list of items. However, it is actually a fixed list followed by a separator bar and then a dynamic list (similar to the left side of the finder). I implemented this using two NSTableViews, each bound to an array controller. The problem is that even though they are two separate table views, they need to behave together like one table view that does not allow a multiple or empty selection. I got most of the way there using a combination of selectionShouldChangeInTableView, tableViewSelectionDidChange, and some toggling of setAllowsEmptySelection. However, there always seems to be a way to trip it up and get to a point where nothing appears selected or something appears as selected in both lists.

I'm stating to think there might be a cleaner way to accomplish this goal. I'm relatively new to bindings so perhaps I'm making things overly difficult in how I am using my table view delegate to change the current selection in the array controllers. Not necessarily some code but any thoughts about a different way to approach this would be much appreciated.

Thanks, Jason _______________________________________________ Do not post admin requests to the list. They will be ignored.
