Redirect page
I'm developing a project in portlet mode and I have a problem with page
redirect:
- I have 3 pages named A, B, C.
- In page named A, I have a page link to page B, then I want B auto redirect
to page C
The problem is that in B class I don't know how to redirect to C. I try to
call
---------- B class -------------
@InjectPage
private C c;//page C
Object onActivate() {
return c;
}
------------------------------------
i don't know in B class which phase (which method) can redirect to other
page.
I did try add a action link to B, then when A call B, in B I click to the
action link, then I have C. But I don't want to click page B again. I want
to click page A then it call to B and in B it auto redirect to C.

I just spent a bit of time looking for how to redirect, I got halfway through
http://wiki.apache.org/tapestry/Tapestry5RedirectException but LinkFactory
is not a part of 5.2. This threads placement was fortuitously placed. Thanks

Tapestry already provides a very elegant and flexible way of doing
redirects, so I think there's no need for a redirect() method.

The fundamentals are still the same, the implementation has changed. But
they won't change again. The whole T5 team is committed to that.
Howard himself said that using exceptions for redirections in T4 and below
was a very bad idea. And I agree.

help a brother out with some redirect code.

The documentation is here:
http://tapestry.apache.org/tapestry5.1/guide/pagenav.html.
A little example: suppose you want to redirect from page A to page B
depending on some logic:
public class A {
Object onActivate() {
boolean redirect = ...; // any logic here
if (redirect) {
return B.class;
}
else {
return null; // continue normal page processing
}
}
}
It can't get much easier and elegant than that. :)

I wish it were built into Tapestry 5 too. It was in previous versions. I
don't fully understand why Howard took it out, and I don't know of any
built-in mechanism to abort the current page and redirect to another. I
guess this is why somebody created the wiki entry. I followed it (with some
modifications) and it works for me.

Thanks you so much. Maybe I have to follow this link:
http://wiki.apache.org/tapestry/Tapestry5RedirectException
Is there any built-in for this? I think that my problem is rather common.
Why don't you make it be a tapestry built-in?

Re: Redirect page
Posted by Benny Law <be...@gmail.com>.
I would try something like this:
in B class...
@PageAttached
private void redirectToC() {
// ...
throw new RedirectException("..."); // URL for C
}
You will need to create RedirectException. I believe there is something in
the wiki on how to handle this exception in AppModule.
Hope this helps.

This should do the redirection. If not, try making your onActivate method
public. You could also return C.class.
