Indeed, I tested your (Ted's) code. It will work with
<property name="nextPage" persist="session"/>
as well as
<property name="nextPage" persist="client"/>
If we are to believe Kent Tong, "client" might be the better choice here.
Good luck!

You sure you set the value to stay persistent in the .page/jwc file?
Just from what you provided it doesn't appear to be.

one stange thing is that the callback i set doesn't persist in the login page.
public abstract class LoginPage extends BlaskanBasePage {
@Bean
public abstract ValidationDelegate getDelegate();
public abstract String getUserName();
public abstract String getPassword();
public abstract void setNextPage(ICallback callback);
public abstract ICallback getNextPage();
public void doLogin(IRequestCycle cycle) {
ValidationDelegate delegate = getDelegate();
if(!delegate.getHasErrors()) {
try {
UserState user = getUserState();
user.doLogin(getUserName(), getPassword());
ICallback callback = getNextPage();
if (callback != null) {
callback.performCallback(cycle);
} else {
System.out.println("callback was null");
cycle.activate("Home");
}
} catch(LoginException e) {
//add error to delegate
delegate.setFormComponent(null);
delegate.record(getMessages().getMessage("login-error") +
"
(" + e.getMessage() + ")", ValidationConstraint.CONSISTENCY);
}
}
}
}
my page that redirects to the login page looks like this (only showing
important stuff)
@InjectPage("Login")
public abstract LoginPage getLoginPage();
public void pageValidate(PageEvent event) {
if(!getSessionScopeManager().exists("user-state")) {
LoginPage login = getLoginPage();
System.out.println("setting callback");
login.setNextPage(new PageCallback(this));
throw new PageRedirectException(login);
} else if(!getUserState().hasAdminAbilities()) {
throw new PageRedirectException("Home");
}
}
now the output I get is:
setting callback
callback was null
so for some reason the callback is set before the LoginPage is
activated and then when i login (all happening on the loginpage) the
callback that is supposed to take me back is null :(

I'm looking at it right now. I remembered that it was in Kents book I read it.

It indeed uses ICallback.

Hi!
If in the middle of an application a user need to login to proceed it
would be nice to be able to get back to the place he/she came from
after login/registration is completed.
My first thought was that I could save the IPage I'm coming from, but
then I remembered that I have seen this beeing done somewhere, and
that they didn't use IPage.
Could someone please lead me in the right direction?
