I've found that the easiest thing to do is just remember the url that your
user was trying to load in the first place.
In my base page I have this:
@InjectPage
private Login _loginPage;
public Object onActivate(Object[] context) {
// Only let the request through if the user has logged in
if (!_loginStateExists || !_loginState.isValid()) {
_loginState = null;
final Link link =
_linkSource.createPageRenderLinkWithContext(_resources.getPageName(),
context);
_loginPage.setSuccessLink(link);
return _loginPage;
}
return null;
}
Then when the form is submitted to the login page I have this:
/**
* Where to go after a successful login.
*/
@Persist
private Link _successLink;
Object onSuccess() {
if (_successLink != null) {
final Link link = _successLink;
_successLink = null; // we only use the link once.
return link;
}
return Index.class; // no link set, just go to home page.
}
