This doesn't look right to me. Your data source should be an array of dictionaries, not an array of cell contents. Also, this code you provide makes no reference to the table column. I don't understand how this could possibly work.

At the most basic level, your -tableView:setObjectValue:forTableColumn:row: method should look something like:

- (void)tableView:(NSTableView*)table setObjectValue:anObject forTableColumn:(NSTableColumn *)col row:(int)rowIndex
{
NSParameterAssert(rowIndex >= 0 && rowIndex < [myTableData count]);
[[myTableData objectAtIndex:rowIndex] setObject:anObject forKey:[col identifier]];
}

Just want to tell everyone that it works now but it's very strange.

This code was missing in my app:

- (void)tableView:(NSTableView*)table setObjectValue:anObject
forTableColumn:(NSTableColumn *)col row:(int)rowIndex
{
[myMutableArray replaceObjectAtIndex: rowIndex withObject: anObject];
return;
}

But this code was also missing from the app yesterday that worked. I have
had no other problems since the project started at least 1 year ago, all
the time with this code missing. What conclusions can I make from that? I
really don't know... ;-)

Dear list!

Yesterday I subclassed my NSTableView so the user can edit a row and press
return to exit the editing process, everything worked as expected. Today I
did the same thing to another app. But when I have edited the row and

press

return the text in the row is not changed to the one I have typed. It
changes back to the text that was in the row before the editing took

place.

Can someone tell me what's going on here? Very strange...

Best regards Peter
