I'd recommend that you find another way of accomplishing your task.
Best practice for JSF is to use a single form tag for the entire page.
I then use sandbox:subForm tags to perform selective, partial validation.

Hi Guys!
I'm having a strange problem. I have two forms in one page, one that allows
me to insert and edit data and other that shows a list of the data that I
have, the list is scrollable and sorteable and I can click into one item of
the list to fill the main form an edit the data. If I send the fields of the
main form without data I have a validation error because all of them are
marked as required but after that when I click into any of the list items
they are not being shown in the main form but they do in different forms at
the same page.
Does anybody know why is this happening?
Thanks,
Johann
