thanks guys, tim i do agree with your pseudo-rant- there are just too many things in flex that should be easy or 'no-brainers'. This being a perfect example. Flex is awesome, make no mistake, but I think enough people do this sort of technique to build it in to the framework- hopefully for next version. Working with forms is another process I would love to see refined for the next version but I'm getting off topic.
yeah i noticed that 'prompt' actually goes away when you select another option- so I put a button next to the cbo to set it to selectedIndex = -1 which works but is ugly. alex i'll try to follow your example. d.
