Re: Newbie problem with protocol

The NSTableDataSource is an informal protocol so you can't claim that
you implement it.  This is done so that you can only implement part of
the protocol if you don't need the whole thing, I think.

Just set the object instance as the data source for your tableview and
it should just work.

Hope that helps,
Jeff.
