and how a component can get to know the page in which it is included? I
mean, I can't @InjectPage, as the component will be included in many kinds
of pages.
@Kristian: thx for the many ways :) I'll try these, hope that the
@Environmental stuff is scalable (I'm trying to bypass session creation as
much as possible)
Is there a doc on the various annotations available?
@Michael:
Could you include a tiny bit of example? THX!
Thx to you all
cheers

5) @InjectPage the page and call the getter

hi janos,
there are several possibilities:
1) declare a component parameter and pass in the variable
2) put it in a ASO and inject the ASO in all your components (using
@ApplicationState)
the drawback is that any other page or component will be able to access
the ASO
3) put it into the Environment and read it whereever you need it in your
nested components.
be careful when you put your object in your environment. if you put it
in
during the action
request it will not be able in the render request (because of the page
redirect).
page:
@Inject Environment env;
@Persist("flash") whateverclass w;
onActivate(w) { this.w= w }
setupRender() { env.push(whateverclass.class,w);}
components:
@Environmental Whateverclass var;
4) define a service that can take this variable (and saves it
appropriatly
so it is not
lost on a redirect:)) and inject your service in the components where
needed
to retrieve the value.
maybe there are some more possibilities :)
g,
kris

page activation + components
Hi there,
I have an activatable page, in its onActivate(String param) method I
save
the param to a normal instance variable of the page class (no
persistence!).
How can any component embedded within this page access this variable?
the page class:
//...
private String param;
public void onActivate(String param) {
this.param = param;
}
public String getParam() {...}
Thx in advance!
Janos
