RE: help me with using bean

[David Friedman]

Mike,

When you use form-property with a form-bean, don't you need to make the main
Bean a DynaActionForm or a class you extended from DynaActionForm?  Where do
you initialize the form-property "bean".  For DynaActionForms, they
initialize to null, per "If you do not supply an initial attribute, numbers
will be initialized to 0 and objects to null" from the document:
http://jakarta.apache.org/struts/userGuide/building_controller.html#dyna_act
ion_form_classes

Regards,
David
