@Page(role = LoginPage.class) question
Hi all,
When using Errai with Keycloak(KC) as a security provider, one of the great advantages of KC is that the Errai developer does not need to provide a login page.
Yet the Errai secuirty demo does provide one, and my app fails to compile if I do not have such a page (see below). As I plan to put a KC signup/signin link on each of my app pages' top navigation bar, do I have to annotate all of my pages with @Page(role = LoginPage.class)? The error message below indicate this is not possible as there can only be one such page? Or, do I need to create a fake login page to silence the Errai compiler gwt plugin, which I will never use? Or, should I annotate just one of my pages, but have the SignIn link to KC appear on all app pages?
Here is the reason I need this:
My app should work fine without the need for a user to sign-in (e.g. support anonymous users), but s/he can choose to sign in on any page (nav bar) at any moment, in which case additional functionality will become available. That is why it makes no sense to have a single login page for that app.
