Yes, I put a breakpoint in -viewDidLoad, as well as just letting it run and crash, and then look at the instance variables in the debugger. At both places, the table is a UITableView and the other two outlets are nil. > 2) Interface Builder knows that your table view is a MyTableView?

Yes, the Type field in the xib file's main window, as well as the Class field in the inspector window, show the type as MyTableView. > 3) the other two outlets are actually connected? Yes, the outlets tab in the inspector window shows the file owner/view controller's outlets to be all wired up. And moving the mouse over those items highlights the corresponding views in the main xib window. > 4) File's Owner in the XIB for the controller is actually of the controller's > class?

No, my MainWindow.xib has a tab bar controller that has a tab item referencing this view controller and its corresponding nib file. > 6) the class of the controller for that tab (in MainWindow.xib) is declared > to be of the right class? Yes, and the controller is being instantiated as expected. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
