Hi Rick
I created a class that extends DynaActionForm and checked the parameters to
determine the size of the array. After I determine the size of the array I
set the attribute with a new array. I tested the code but after the reset
method I get:
java.lang.IllegalArgumentException: No bean specified at
org.apache.commons.beanutils.PropertyUtils.getPropertyDescriptor(PropertyUti
Skip dealing with the reset method for a while. Can you even get the
form to display without the reset method? This sounds like you having
something named wrong in regard to how you are trying to get a form bean
property. Does the error happen on submit? We need a few more details.
Show you dynaForm definition in struts config and the form on the jsp.

The problem is that I have to minimize the use of object in session
scope to minimize session replication. Is there any way to do this in
request scope?
Right.. as I said you can use Request scope just fine. You just have to make
sure in the reset method to either use a LazyList to wrap your Collections
or somehow figure out what size to make to your collection.
(I like LazyLists).
