Charles,
If you the size of the ArrayList is constant, you can
specify the form-property 'size' attribute and this
will fix your problem. Otherwise, you need to use
session scope to store the FormBean. The reason is
that Struts will not size the colRequetes ArrayList
when the form is submitted. If the form is in request
scope, it will already be sized for you.
