I replaced my code with this one:
MyObject *p = [[MyObject alloc] init];
[arrayController addObject:p];
[p release];
[grid editColumn:0 row:[grid selectedRow] withEvent:nil selected:YES];
it works fine, NSTableView selects new row, -editColumn receives
correct row number and starts editing. So, the question is: why do I
need to call -rearrangeObjects? In what cases missing of this call
will lead to problems?
