NSPopUpButtonCell won't Pop Up

I have a table whose NSTableColumns are created dynamically in code. I need to add an NSPopUpButtonCell to one of these columns programatically. I do so with the following code:

NSPopUpButtonCell *dataCell = [[[NSPopUpButtonCell alloc] initTextCell:@"" pullsDown:NO] autorelease];
[dataCell setBor开发者_如何学JAVAdered:NO];
[dataCell insertItemWithTitle:@"[TEMP]" atIndex:0];
[myNewTableColumn setDataCell:dataCell];

The pop up button cell appears in the table fine, but when I click on it, nothing happens. I've tried calling [dataCell setEditable:YES] but when I do that, the cell edits with a field editor like an NSTextFieldCell. Am I missing something?

D'oh! I forgot that the table I was using was an NSTableView subclass that overrode the - mouseDown: method to do something else. As such, I ended up never sending the proper message to the pop up cell to actually get it to pop up.

A quick call to [super mouseDown:theEvent] has everything working as expected.
