Hello,
I was wondering something...
I have an NSTableView which is automatically filled by binding. So,
I did not set any dataSource.
But I want to implement
"tableView:writeRowsWithIndexes:toPasteboard:", which is a
dataSource method. So, I set some object to be the dataSource,
implementing the method.
At run-time, it complains that the dataSource should implement
numberOfRowsInTableView:. I had to implement such a method, but the
return value remains unused since the bindings are responsible for
feeding.
My question is : yes, it works, but what is logical to do ? Should
I also implement dummy "tableview:objectValueForTableColumn:row:"
and others methods that are theoretically required for a
datasource, but practically unused when using bindings ?

Pierre,
I've run into this before. IIRC, the following should be sufficient
to make AppKit happy:
-(int)numberOfRowsInTableView:(NSTableView*)aTableView
{ return 0; }
-(id)tableView:(NSTableView*)aTableView objectValueForTableColumn:
(NSTableColumn*)aTableColumn row:(int)rowIndex
{ return nil; }
