Hi friends,
When the /editRegistration action is invoked, a registrationForm is created and added to the request, but its validate method is not called. The default value of the validate attribute is true , so if you do not want an action to trigger form validation, you need to remember to add this attribute and set it to false .
Hi friends,Yes. If your Action does not need any data and it does not need to make any data available to the view or controller component that it forwards to, it doesn't need a form. A good example of an Action with no ActionForm is the LogoffAction in the Struts MailReader application:
<action path="/logoff"
type="org.apache.struts.webapp.example.LogoffAction">
<forward name="success" path="/index.jsp"/>
</action>
This action needs no data other than the user's session, which it can get from the Request , and it doesn't need to prepare any view elements for display, so it does not need a form.
However, you cannot use the
Thanks.
