Re: Preparing Multiple DynaValidatorForm?s with one action

[Adam Hardy <ah...@cyberspaceroad.com>]

Hi Pat,

are you sure you've got the best approach? Trying to shoe-horn two forms 
into one request tells me generally (when it happens to me) that I 
should refactor the design of whatever use-case I'm working on.

If I have a submit to one action mapping that on success must forward to 
another action mapping with a completely different form, I use a 
re-direct. Of course it drops all the data in-between but you're better 
off in the long run.
