Re: Page iteration & redirect in Cocoon

[Oleg Konovalov <ol...@yahoo.com>]

Hi,

What 

I see that act() method has redirector parameter, 
don't know what it is for or how to use it:
public Map act(Redirector redirector, SourceResolver resolver,
Map
objectModel, String source, Parameters par)
which is a method of class:
ExecuteCDAAction extends AbstractMbrAction implements
Composable,
Configurable, Disposable

Any examples of using that redirector ?

There is also RedirectTransformer implemented but never used:
public class RedirectTransformer extends AbstractSAXTransformer

What is that for, any clue ?


Sorry for the newbie questions.

Any help is very appreciated.

TIA,
Oleg.
