Thanks for the advice (and quick response).

I'm definitely conencted to the table view because I'm also serving as the
datasource, and in the -(int)numberOfRowsInTableView:(NSTableView *)x
function,  I have
        if(x!=_theTableView){
                NSLog("Wrong tableview");
                return 0;
        }
and this condition is never matched (the table view successfully gets its
data, and the log doesn't have anything).
