Hi Corbin,
Thanks for fast reply! Just as Jens said, I have checked the table and
I am sure that it is not nil:
Printing description of dataTable:
<NSTableView: 0x7d85b80>
(gdb) continue
I also debugged the table source and I can get the count correctly(not
zero)
2008-07-15 13:05:23.683 Roboplasm[1892:813] [[[[appController
tableController] tableSource] items] count] = 2
(gdb) continue
However, the method -numberOfRowsInTableView has never been called
since I added a NSLog there:
- (int)numberOfRowsInTableView:(NSTableView *)tableView {
NSLog(@"Method -numberOfRowsInTableView is called with count %d.",
[items count]);
return [items count];
}
since the log message has never been found. The same problem happens
for -tableView:objectValueForTableColumn:row:. Could you help me to
figure out what the problem is? Thanks!

As Jens said, it sounds like you may have a nil dataTable. Check
that first.
Second, break on:
- (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView;
and make sure you aren't returning 0, which would cause the other
method to not be called at all.

You are right. I found that the -
tableView:objectValueForTableColumn:row: has never been called...
Any way to fix this problem?

The problem is that after I update the data source, which is
tableSource in tableController, [dataTable reloadData] will not
update the table view in the window
You're sure that, at runtime, 'dataTable' is not nil? It's easy to
overlook an outlet when wiring up the nib, and a nil object
pointer acts as a no-op.
If that's not the problem, add an NSLog call to your -
objectValueForTableColumn: method, so you can see whether it's
getting called again after you call reloadData.
