Hey Guys,
I hate to bother you again. But -- is there a way to get the currently
selected data from this set? For example, a user hits the page and all
choices are displayed fine. But, they pick some choices. They haven't
finished editing the form or maybe they made a mistake, anyways they land in
the form_invalid land. I'd like to be able to use this same technique to
make sure I properly display what the user has selected thus-far.
Thanks!
