Re: Field.Choices in Template

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!

I remember trying to help you with this on IRC, Kurtis. I've had the
same problem before, but I could never remember that BoundFields have
a field attribute.. If there isn't a note in the docs (or even better,
an example), I'll make sure to write a patch in the next few days.


Cheers,
