Re: redirect request for Page A to page B without contructing A?
Implemented a SimplePageAuthorizationStrategy; works but there is a gotcha:
Say the home page has a (non-ajax) login form:
1. unauthenticated users navigates to home page and is authorized
2. user submits valid login info.
3. At this point I'd assumed Home page would be re-requested (does wicket do
Redirect-after-form-submit?)
4. However, Home page is redisplayed and isAuthorized method is never
executed after form submit.
Workaround seems to be doing setResponsePage in onSubmit method. This,
however, seems to complicate creating a reusable LoginPanel which would
return user to same page.

public class HomePageAuthorizationStrategy extends
SimplePageAuthorizationStrategy{
public HomePageAuthorizationStrategy(){
super(HomePage.class, ProfilePage.class);
}
/**
* if user's signed-in redirect request for Home Page to user's
dashboard/profile
*/
protected boolean isAuthorized() {
this.getLogger().info(checking auth for home page access...);
return ! ((MySession)Session.get()).isLoggedIn();
}
public Logger getLogger() {
return Logger.getLogger(this.getClass().getName());
}
}

So, for example below, PageA = site home page; PageB = user's own profile
page
Sounds like a custom authorization strategy would work great here.

Why do you want to do this?

Hi,
I'd like to redirect requests for page A to page B without constructing page
A. Typically I'd use URL parsing in a servlet filter to accomplish this but
would like to figure out an OO way to do so.
In my RequestCycle I tried:
@Override
protected void onBeginRequest() {
if(PageA.class.equals(this.getResponsePageClass()) someCondition)
{
this.setResponsePage(pageB);
}
super.onBeginRequest();
}
The problem is that this.getResponsePageClass() is null in onBeginRequest.
Is overriding a RequestCycle method the right way to address this problem?
If so which method should I override given that:
-I need to ascertain that intended request target is PageA
-I'd like to avoid constructing page A
thanks

If it is intercepting what you're after (like you'd do when enforcing
authorization), look at IComponentInstantiationListener. What is your
use case?

What I have done is to check in MyApplication.getHomePage():
public Class getHomePage() {
IUser user = getMySession().getCurrentUser();
return user == null ? Index.class : UserHome.class;
}

That's another fine solution if the home page is only what you're after.
