I believe I understand the principle of FormDef - you're combining the form definition with the validation rules. So is that why you want to nest indexed ActionForms rather than any old type of DynaBean? Are you then calling the validate() method on each of the indexed ActionForms?
You're right if you want a properly initialized lazy ActionForm then you need to go through the FormBeanConfig's createActionForm method. Having said that the default "indexed" property type of LazyDynaBean/LazyValdatorForm is an ArrayList - changing that to a LazyDynaBean[] as I showed in the CustomLazyBean means there is no need to then initialize that indexed property - its done automatically for arrays (CustomLazyBean would instantiate a new DynaBean and grows it accordingly). >From reading the message on the FormDef user list, then just having a property which is a CustomLazyBean (rather than CustomLazyBean array) sounds like it would work for your user - then only thing then is I don't really understand how that then interacts with FormDef - hence my questions at the top. Sorry, should have got round to giving FormDef a go - but lifes busy :-( Niall ----- Original Message ----- From: "Hubert Rabago" <[EMAIL PROTECTED]> To: "Struts Users Mailing List" <[EMAIL PROTECTED]> Sent: Friday, October 01, 2004 9:43 PM Subject: Re: Indexed Properties and Lazy List behaviour > But if I need it to be a DynaActionForm subclass, then I'd just use > LazyValidatorForm or its subclass, right?
