But if I need it to be a DynaActionForm subclass, then I'd just use LazyValidatorForm or its subclass, right? In which case, wouldn't I have to worry about it being properly initialized, as indicated in http://struts.apache.org/userGuide/building_controller.html#dyna_action_form_classes ?
Someone asked about combining FormDef and LazyBeans to come up with a form containing indexed properties. FormDef works with DynaActionForms. If I have an array or list of dyna forms, I can use FormDef with each element. The problem is coming up with a lazy, non-session-scope implementation. I came up with the code snippet at https://formdef.dev.java.net/servlets/ReadMsg?list=users&msgNo=12 because I assumed that in order to create a proper ActionForm, it needed to go through FormBeanConfig's createActionForm. Are lazy dyna forms exempt from this requirement?
