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?
