I guess your problem is because you set the NSOwner as the delegate of
the TableView (as show the figure 4-42 in that tutorial). You should
connect the instance of the class where you have the method
-numberOfRowsInTableView. Of course you should first add this class at
Gorm and make an instance of this.
