Does validator work with Lookup dispatch action
Hi,
I am using struts for my application. I have 3 buttons in my form i.e
prev,next,clear.
I read few articles and found that Lookup dispatch action will be the best
option to use.
I have few concerns using lookupdispatch action,
1. Will I be able to validate using struts validator?
2. I need to validate only when next button is hit, is that possible?
Is there any tutorial avialable for using lookup dispatch action.
Thanks
Mosho

Re: Does validator work with Lookup dispatch action
Posted by mosho <ro...@gmail.com>.
I have two submit buttons previous and next.
I need to validate only when I hit next button. I can control this by using
page attribute in valdation.xml.
This works for server-side. It doesn't work for client side validation.
How can I do client side validation only when i hit next button.
Is there any solution for it?
Thanks for your help.

Hi Wendy,
As per my requirement, I need to validate only when next button is hit. I
can validate manually for server-side validation, it is working. How do I
control for clients-side validation?
If I include javascript tag in my jsp, it is going to validate even if I hit
previous or next button.
Thanks for your help

There's a *much* better option in EventDispatchAction. It's available
in Struts 1.2.9
http://struts.apache.org/1.2.9/api/org/apache/struts/actions/EventDispatchAction.html

Yes, Validator works fine with dispatch actions. For 2, take a look
at this tutorial on calling validation manually:
http://www.learntechnology.net/validate-manually.do
It sounds like you have a wizard-type form, so you can make use of the
<field> 'page' attribute in validation.xml to validate the fields on
all pages up to the current one.

You also need to override the
protected Map getKeyMethodMap(){
}
to map the buttons to the dispatch methods.
Hope that helps

I have another question, I was just trying to use LookupDispatchAction. It
looks like if I am extending LookupDispatchAction, I don't have to use
excute method. Is that right? I can do all the processing in the respective
previous and next methods.
Previous methods looks like ..for ex:
public ActionForward previous(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
// do add
return mapping.findForward("previous");
}
Wendy,you are right my application is a wizard.

Thanks for all the replies.
Wendy, I am using struts 1.1 so I don't think I can use EventDispatchAction.
Adam,
what is the difference between MappingDispatchAction and
LookupDispatchAction. Any advantages over LookupDispatchAction?
Also, do you have an example of how to set page attribute and use client
side script to set the page request parameter.
I am new to this, all your help is appreciated.
Mosho

I've done something similar by explicitly calling form.validate() from
within the "execute" method, but this has a bad smell. Someone else
probably has a better approach.
