I'm not entirely sure about this really - but it looks like you aren't
returning the image unless you just left this out of your description of
the error. You want to implement this in your dataSource class:

public Object tableViewObjectValueForLocation(NSTableView tv,
NSTableColumn tc, int i)
{
try{
if(tc.identifier().toString().equals("statusColumn"))
{
if(statusArray.objectAtIndex(rowIndex) == "")
return statusGoodImage;
else
return statusBadImage;
}
}
catch(Exception e)
{ /* this whole try catch block is from another example - but i
don't have the 10.1 tools yet - so i didn't know what to remove and just
typed this in by hand. */
return "Exception (could be unlabeled identifier in IB)";
}
}


like i mention in the comment above - this is typed in to mail.app - so
there might be some bugs - but it should help...

good luck,
Tyler
