Makes sense. Thank-you for your help. -----Original Message----- From: Leonardo Uribe [mailto:lu4...@gmail.com] Sent: 10 June 2014 17:57 To: MyFaces Discussion Subject: RE: Declaring a node that is not type 'view' as the start node.
Hi It looks like if "register" bean was in the flow scope associated with the flow to evaluate. The lookup will fail, because when the start node outcome is calculated, you have not entered the flow yet. The algorithm works in 2 steps: calculate the final outcome and then perform the transitions. I don't see any problem, because it is expected to fail in that scenario.
