Then you need to implement *all* of the required methods in your data
source object. It's an all-or-nothing deal. Like Adam said, all you
need is "do nothing" methods like returning 0 from
"numberOfRowsInTable:", etc.

I need to have the subclassed arraycontroller datasource to support

Check in IB to make sure you haven't connected the table view's
"dataSource" outlet. Since you're using bindings, the table view
doesn't need a data source object. You might also have called
"setDataSource:" in code somewhere.

Well,
nothing against it. But I didn't have these methods implemented,
everything worked and suddenly I get this error.

Just implement both of the methods referenced in the assertion
and return anything you want (probably 0 for
numberOfRowsInTableView: and nil for
tableView:objectValueForTableColumn:row:)
Bindings will still do its magic, everything will still work,
and you will not get those errors.

Hi folks,
I have ann issue which is driving me nuts. I'm writing a small
app, where I use bindings. I implemented a subclass of
NSArrayController to support drag&drop into my tableview.
My problem is that the console started to report:
*** Illegal NSTableView data source (<DDArrayController:
0x35e6f0>[object class: RCTPath, number of selected objects:
0]). Must implement numberOfRowsInTableView: and
tableView:objectValueForTableColumn:row:
Everything is working correctly but this error is very annoying.
Any idea?
Robert
