Hi all,

I'm trying to do a form wizard w/o having to download anymore thirdparty plugins like struts-flow or livinglogic.de so i found the example on apache's newbie faq.

I also created an Action class that extended the LookupDispatchAction.

I followed the instructions on the LookupDispatchAction javadoc by creating the form-bean entry in my struts-config.xml and made the following jsp changes. In my Action class that extends the LookupDispatchAction, I added the two methods per the instructions:

public ActionForward add(ActionMapping mapping,
          ActionForm form,
          HttpServletRequest request,
          HttpServletResponse response)
          throws IOException, ServletException {
      // do add
      return mapping.findForward("success");
  }

  public ActionForward delete(ActionMapping mapping,
          ActionForm form,
          HttpServletRequest request,
          HttpServletResponse response)
          throws IOException, ServletException {
      // do delete
      return mapping.findForward("success");
  }

However it seems that those two, methods are never called. Only the

public ActionForward execute(...)

method is invoked when I click on any of the buttons. What am I missing here?

tia,

Patrick

In case you're wondering, I did also include that getMapKeyMethod(...)

protected Map getKeyMethodMap() {
      Map map = new HashMap();
      map.put("button.add", "add");
      map.put("button.delete", "delete");
      return map;
  }

did u correctly defined button.add and button.delete in ur resource bundle
and did u use that correctly from jsp

Yes, my resources are working fine.

The lookupDispatchAction javadoc mentions defining that getKeyMapMethod and adding your methods for the key values of your buttons, but when are those new methods ever invoked?

I looked at the source code of LookupDispatchAction and it only invokes the getKeyMapMethod when you do a lookupMethoName call.

Am I suppose to add logic in my execute method that determines the methodName (add,delete,...) and then call the added add(...), delete (...) methods? I thought it was suppose to happen automagically?

What am I missing here?

thanks,
Patrick

What I really hate are discussion groups that identify my problem exactly, yet the solution was never solved!!

In case you sympathize with my dilemma, I think i solved this problem. The execute method is not to be overwridden in your LookupDispatchAction subclass -- you just depend on the getMapKeyMethod to address that. My problem was that my action tags were not properly defined.

If anybody's interested in a concrete example of the LookupDispatchAction class for a wizard like multipage form, here's the code

Thanks for posting your solution. Most of the time people dont't do this once their problem is solved!

Hi patrick
I couldnot goto the Code page as it is showing some error message. can you please guide me how to get there.

bye
Thanks

Sorry, I recently upgrade my website. Check again, that link should redirect you to the proper page. If not here it is:
