ActionDispatcher and Validation

[Henry Lowell]

I am using ActionDispatcher and EventActionDispatcher for my Action classes. For whatever reason, when I do this, the form is trying to be validated the initial time the JSP is being rendered. Because of this, it goes into a validation loop and throws a StackOverflow. If anyone knows why this is happening, it would be much appreciated.

Thanks. Here is the code.

AddUserAction.java

public class AddUserAction extends Action
{
    
    protected ActionDispatcher dispatcher = 
        new EventActionDispatcher(this);
    
    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
    {
        return dispatcher.execute(mapping, form, request, response);                
    }
    
    public ActionForward view(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
    {
        System.out.println("View");
        performViewLogic(request);        
        return mapping.findForward("view");
    }
    
    public ActionForward save(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
    {
        System.out.println("Going Save");
        performViewLogic(request);
        return mapping.findForward("view");        
    }
    
    public ActionForward delete(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
    {
        System.out.println("Going Save");
        performViewLogic(request);
        return mapping.findForward("view");        
    }
    
    
    protected ActionForward unspecified(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception
    {
        System.out.println("Nthing here");
        performViewLogic(request);      
        return mapping.findForward("unspecified");
        
    }   
    
    private void performViewLogic(HttpServletRequest request)
    {
        // DAO's are accessed here and view data is placed in 
        // the request
    }
    
}

struts-config

<form-bean
   name="addUserForm"
   type="org.apache.struts.validator.DynaValidatorForm">
      <!-- PROPERTIES FOR BEAN HERE
           EXCLUDED TO SAVE SPACE -->
</form-bean>
 
<action 
   path="/AddUser"
   type="web.action.AddUserAction"
   name="addUserForm"
   parameter="save,delete,view,default=view"
   validate="true"
   input="/AddUser.do">
      <forward name="view" path="/add_user.jsp"/>
      <forward name="unspecified" path="/add_user.jsp"/>
</action>

[Dom Lassy]

Are you initially calling /AddUser.do? If so, it is performing validation because validate is set to true. I don't use dispatcher that often, but I think you would want one action to load the page (with validate="false") and use the dispatcher for the submittal (add, edit, etc..) and validate="true".

Tha's what I've done to get past the issue. I am assuming this is the only way if using auto validation?
