change view id before render
Hi everybody,
I'm pretty sure that the answer is already in the list... but i can't find
it... sorry.
I've to do something like this:
1) click on a commndButton -> outcome -> new page
2) *before render* new page -> some beans' initialization
I knew I can do this either in the constructor of backing bean or with a
managed setter properties (or maybe a PhaseListener, actually i don't now
how...)
But I need one more step:
3) If some conditions are true -> go to another page (another view)
I can't understand how can I do this. In which method? In which phase?
Thank.
Stefano.

I'm not sure if this will help you or not but it worked for chaining a login for me:

I suppose so... I think It's a little bit weird... IMHO Render phase listener should be fired again...
Thanks a lot! Your component will be very useful anyway!

I doesn't look like it would work right now. The phase listener is
only called once, the lifecycleimpl doesn't care if the viewId is
changed. So to support chaining, I would have to implement it myself
in the onload code.

Re: change view id before render
Posted by Andrew Robinson <an...@gmail.com>.
I'd have to look into it. Since it is a phase listener, it would have
to be called before the view is rendered. I am not sure if when a new
view is created as a result of navigation, if the lifecycle component
re-fires the phase listeners.

Re: change view id before render

Thank you, your component is really interesting.
I take a look at the source and It seems to me I need just one more thing
(correct if I'am wrong):
Page A -> Page B
I can do some initialization before render page B,
If, with your component, I add an an action method with an outcome that
makes me go to Page C, I can do
Paga A -> Page B (not rendered) -> Page C (for end-user Page A -> Page C)
But If I have some logic in Page C initialization that makes me go to page
D?
If I've understood I can't do this because the PhaseListener isn't fired
again before Page C render, right?
I mean: rules aren't chainable, are them?
I think is somehow possible to do something like that... but maybe I'm just
trying to raise universe entropy :)
Stefano.

Have a look at my on-load component:
http://jsf-comp.sourceforge.net/components/onload/index.html
Or use the one from JBoss-Seam or Shale
