Re: redirect-after-post pattern

[Filip S. Adamsen]

I think what you want to do is to simply return null if you find any 
errors. Tapestry won't redirect, then.

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.
