Oh, right. Best thing you can do here is wrap the user request in a
model: PropertyModel doesn't allow a null model, but a model that
produces null is fine. So this should work:
public SignInSuccess(String id) {
super(id);
IModel m = new AbstractReadOnlyModel() {
public abstract Object getObject(Component component) {
return getCustomSession().getUser();
}
}
add(new Label("username", new PropertyModel(m, "firstName")));
SignOutForm signOut = new SignOutForm("signOutForm");
add(signOut);
}
or even:
public SignInSuccess(String id) {
super(id);
add(new Label("username", new PropertyModel(new
PropertyModel("customSession.user"), "firstName")));
SignOutForm signOut = new SignOutForm("signOutForm");
add(signOut);
}
