I'd love to use this, but I'm worried about losing the lovely "ValidatorForm" that my BaseForm extends. Any way I can use the Validator form with the "DynaActionForm"?

I also added a way to configure the initial value for dynamic properties that is used in the reset() method. So, you could preconfigure the logon form's values like this: <form-bean name="logonForm" type="org.apache.struts.action.DynaActionForm"> <form-property name="username" type="java.lang.String" initial="user"/> <form-property name="password" type="java.lang.STring"/> </form-bean> much the same as you can preinitialize normal instance variables with initial values when the bean is created.
