On transition evaluate redirect to a view without showing FacesMessage
On transition, my flow redirect without rendering the FacesMessage contained in the FacesContext current instance, the issue is the same with the MessageContext.
The service layer is functionally tested so it might not come from this area.
the whole code is available there
the portion who should causing troubles are linked there :
in the flow xml definition file the statement
should display the facesmessages, instead it's redirect to the next step on the next view with messages into the facescontext (spyed on the console) but not rendered
<view-state id="enterRegistration" model="model">
<transition on="cancelRegistrationAction" to="exitRegistrationAction"/>
<transition on="validateRegistrationAction" to="reviewRegistration">
