Send Redirect after Login
Hello,
I'm using the Layout component for authentication purposes. The general auth process is happening outside of the application via SSO, but all my pages have the Layout component.
Every time I request a page, The Layout component looks if a session user has been created, and if not, creates the user using a service and stores him in the session.
Now, at the end of the creation process, back in the Layout component, I want to redirect based on the roles a user has.
So I decide which page to redirect to based on the role, and do the following:
response and pageRenderLinkSource are both injected in the component.
response.sendRedirect(pageRenderLinkSource.createPageRenderLink(getPageForRole()));
But when redirecting, my Tomcat logs an exception:
java.lang.NullPointerException

What is the problem here? Can't I send a redirect from a component?
Or is there a better way to do this? Something that intercepts all requests, creates the session user and redirects if necessary?
Regards,
Daniel P.

Never use response.sendRedirect() in a page, component or mixin. Just
return the URL you want to redirect to in your event handler event:
java.net.URL or page instance injected using @InjectPage or a logical page
name as a String. This works in pages, components and mixins. More
information on https://tapestry.apache.org/page-navigation.html.
