Redirecting to page on load
I would like for a given page to force a redirect to a different page before
it's rendered if a given condition is met.
I could use a simple Response.sendRedirect but that would mean i would have
to provide the page name in string format. I would like to avoid having to
do this because it would make code refactoring harder and more error prone.
So, any way i can redirect using page classes only ?
Thanks.

A tip... I don't know if the code for your checking is heavyweight, but
sometimes it's recommended to check in the onActivate() if the request is a
XRH or not... because component events triggers it too. You can do so by
@Inject'ing Request (org.apache.tapestry5.services) and calling isXHR()
method.
Of course, that is only necessary if the code is heavy and your XHR checking
for redirection isn't needed...

The onActivate() return value is the way to go in Tapestry. Using
Response.sendRedirect() should only be used in RequestFilters and
Dispatchers.

Hi Hugo,
what u could do is to create the Link to the page u want to send
redirect and then use the response. It would be something like:
Link redirectTo =
pageRenderLinkSource.createPageRenderLinkWithContext(pageClass,
context);
response.sendRedirect(link);
I hope it helps! :)

I believe you can do this by having onActivate() return a Page, or just
the string name of your page:
public String onActivate() {
... test for condition
if (condition) {
return "MyPageName";
} else {
return null; // keeps you on this page
}
}
onActivate() is called before any rendering.

I would like for a given page to force a redirect to a different page before
it's rendered if a given condition is met.
I could use a simple Response.sendRedirect but that would mean i would have
to provide the page name in string format. I would like to avoid having to
do this because it would make code refactoring harder and more error prone.
So, any way i can redirect using page classes only ?
Thanks.
