Re: NSTableView and loadNibNamed

The method that loads the NIB is:

-(void)loadTableController{
    if (tableController == NULL) {
        tableController = [[TableController alloc] init];
        if (![NSBundle loadNibNamed:@"tableWindow" owner:tableController]) {
        NSLog(@"Error loading TableController");}
        else{
            NSLog(@"TableController NIB Loaded");     
        }
        [tableController loadWindow];
    }     
}

After the aloc init step
tableController is 0x380060
dataTable is 0x0

At a break at the NSLog(@"TableController NIB Loaded") call
the values are unchanged

indeed, the file's Owner is TableController and dataTable is connected
to the NSTableView object in the NIB.

Thanks,
Joseph Ayers
