Thank you Rick, James and Craig for your inputs. The answers is exactly what I was looking for in order to get off my lazy a** and break things apart.
I was trying to set a quantity field do indicate how many child forms to display in one step without using an action with the nested tag lib. Happy new year. -----Original Message----- From: Craig R.

What's > the best way to do that in the ActionForm There are no guarantees on the order that the setters are called. This is for two reasons: * There is no rule in the HTTP or HTML specs defining the order in which the request parameters are sent, so it's totally up to the client. And they really do operate differently. * There is no rule in the servlet spec saying that the input order has to be preserved, so it's totally up to the container to decide how to implement this. And they really do operate differently. More fundamentally, though, the only reason that the setter order would matter is if there are side effects (setting one property affects the semantics of setting a different one). Designing your form beans in this way is a very poor architectural decision -- the whole point of a form bean is to simply represent the input values that the user actually entered on the form. Any functionality that tries to assign "meaning" to these inputs should be done in business logic (which can pull data out of the form bean in any order that you need), not in the form bean itself. > > Thank you.
