ok, but i have a prepare action for the DynaValidatorForm where i
initialize one bean, put it to the ArrayList and then set the array list
as property of the form. but i´m not allowd to instantiate or cast the
form because of this:
<action path="/prepareBuyOnline"
type="software.BuyOnlineAction"
parameter="prepareForm">
<forward name="success" path="/BuyOnline.jsp"/>
it seems that a form of type DynaValidatorFrom does´t allow the
attribute name="formName" in the prepare statement and that´s why i´m
unable to set the form property. i always get a ForwardConfig exception
when i try to do this but i need to set this form property in the
prepare statement. is there any other way to do this in a DynaValidatorForm?
