I've read the ILink approach an Howard's blog dated of february 2006 ... 
( http://howardlewisship.com/tapestry-javaforge/tapestry-flash/index.html )

Are you sure the redirection is the good solution ? Is the redirection 
really send a redirect reponse to the client browser ? How could i pass 
parameters to the destination page in the redirect approach ?

In order to redirect, you have to throw a RedirectException.  Have you read

Subject: redirect-after-post pattern

Hi,

I've tried to implement redirect-after-post pattern in Tapestry4 without 
success ...

I've read that the way to send a redirect reponse to the client web 
browser is to return an ILink from the form listener method like this :

        @InjectObject("engine-service:page")
        public abstract IEngineService getPageService();
  
	public ILink doFormSubmit()
        {
                // ...
                return getPageService().getLink(false, getPageName());
	} 

But I can't return an ILink in my listener if an error is found during the
validation of the form :

        IValidationDelegate delegate = getValidationDelegate();
        if (delegate.getHasErrors())
                return;
 
Did i miss something ? What's the trick ??

Thanks in advance for any clue.
