So the NPE comes from my code and it's thrown in the line:
private String email = messages.get("enterEmail");
This is following right after:
@In(create=true) private Map<String, String> messages;
which tells me that the messages-map seems not to be injected.
When I use the simpler syntax with just one line:
@In("#{messages['enterEmail']}") private String email;
org.jboss.seam.core.Messages.getMessages() does not get called.
Though it does get called when evaluating the EL expressions with messages
inside my xhtml.
So it looks to me like injection for session beans is somehow not working.
