Hi!

I'm begining with Cocoa and I'm writing a little application that contains a NSTableView. I drawed the NSTableView in the GUI with IB (10 rows visible).

I have a class as the NSTableDataSource and aparently it works ok, filled my object with the data and set the dataSource for the TableView. When I build and run the application it fills the rows correctly and after the last visible row in the NSTableView it crashes with a Signal 11.

Any idea of what's happening?

Thanks for the help.

Um, code, please?

(I'll assume that is an array bounds problem though. Make sure you are subtracting 1 from your -[NSArray count] and NOT subtracting 1 in the appropriate places. Your data source is probably telling the NSTableView that you have one more row than you really do.)

For basic stuff this seems to work for me..
(notice no subtracting/not-subtracting)

Code:
- (int)numberOfRowsInTableView:(NSTableView *)aTableView
{
return [myArray count];
}

- (id)tableView:(NSTableView *)aTableView objectValueForTableColumn:(NSTableColumn *)aTableColumn row:(int)rowIndex
{
return [myArray objectAtIndex:rowIndex];
}

I guess I'll second the code request because we can't really figure out where you're going wrong without it.

Yeah, IamBob has got a point there. Due to good design on Apple's part, you don't normally need to do any adding or subtracting of 1 for data sources.
