I've not got to dealing with aproblem like this yet, but this will inevitably happen to me in the near future. This is a general issue with a group edit, when two or more fields have some inter-dependancies. In this case I'd attach a ValueChangeListener to all components in the group, pointing them to one method in the managed bean, and then in that method have the logic for the group-edit, grabbing all group components and analizing their values. Also, you may want to add a flag for preventing your logic working more than once per request (in case more then one field value was changed and several listeners fired).

Hi! Does anybody know if it is possible to put a required constraint on a group of elements on a JSF page? E.g. I have a page for register a transfer. It is mandatory to select one from account, enter an amount and select one to account. However, my problem is that the user can select to account from three different lists. I use the required attribute on from account and amount. So my question is if it is possible to group these to account lists in on group and put a coinstraint that a selection must be made from at least on of these lists.
