While I highly agree the redirect-after-post pattern is a good practice. It
only makes sense in some situations. It makes sense to use it when you're
submitting a form and the form submission was successful (ie. Tapestry
"success" event fires). But if validation fails, Tapestry should not be using a
redirect to re-show the form with the validation errors.
When validation fails, it should use the response for the same request for
re-showing the form, it should not be sending a 302. I wish there is a way to
disable redirects for validation failures only.

Subject: Re: Implication of client side redirect
Hi Rajesh,
Tapestry follows the "redirect after post" principle. This has a lot of "pros"
(avoiding double submission of forms, for instance), but if you're really
concerned about it, there's a configuration option to turn it off.
In org.apache.tapestry5.SymbolConstants:
/**
* If set to true, then action requests will render a page markup response
immediately, rather than sending a
* redirect to render the response.
*/
public static final String SUPPRESS_REDIRECT_FROM_ACTION_REQUESTS =
"tapestry.suppress-redirect-from-action-requests";
Cheers,
Robert
