Drag and Drop with Core Data bound NSTableViews almost works

I think I have this very close to working. My understanding is that
for drag and drop to work I have to set some object as the
NSTableView's data source even though technically the table columns
are bound to an NSArrayController for data. In my data source object I
have implemented the nessesery methods for drag and drop.

When the NSTableView has its data source outlet set drag and drop
works fine, but the columns do not get populated with data from the
ArrayController. As soon as I remove the data source outlet the data
returns to being bound to the ArrayController and the drag and drop
goes away.

How can I have a datasouce oulett for an NSTableView to provide drag
and drop support and have the NSTableColumn also get its data from the
NSArrayController it is bound to?


Thanks,
Adam
