Subject RE: DispatchActions - using form validation for only some methods
Date Wed, 30 Jul 2003 14:38:31 GMT
I don't think I can utilise the first approach as I am always using the same
action (via the html form's submit).

The second approach may do the trick - though I'll have to start using the
validator (rather than the default stuff in the action form).

Thanks for your help,

Not sure if anybody answered you question or not yet but there are a couple
things you can do...

1. Have many action mappings to one DispatchAction.  
<action path="/a" parameter="subtask" type="my.Dispatch" ...> ... </action>
<action path="/b" parameter="subtask" type="my.Dispatch" ...> ... </action>

link to each as "/" and "/" and then
do validation per action and not per form.

The other alternative suggested by Robert Taylor, which, once set up, is
pretty slick but involves a little extension to how validator works:

Subject: DispatchActions - using form validation for only some methods


I've just moved to using dispatch actions from my own implementation of
something similair to relay actions. One facility my implementation gave me
was to have the form validated when some actions were called, and not
validated for other actions (at the expense of a bloated struts-config.xml).

Using dispatch actions I am now explicitly calling the form's validation for
those methods that require a validated form:

        ActionErrors errors = form.validate(mapping, request);
         if(!errors.isEmpty()) {
             saveErrors(request, errors);
             return new ActionForward(mapping.getInput());

Is there a better way of achieving this?
