Use a PhaseListener to reinject FacesMessages lost during a redirection to the
JSF context
-------------------------------------------------------------------------------------------
Key: MYFACES-403
URL: http://issues.apache.org/jira/browse/MYFACES-403
Project: MyFaces
Type: Improvement
Components: General
Environment: N/A
Reporter: Enrique Medina Montenegro
Priority: Trivial
Attachments: FacesMessageListener.java
When using redirection to navigate from one JSF view to another, e.g., to
implement the PRG (Post-Redirect-Get) pattern, all the FacesMessage objects are
lost, so the destination view is not able to show any messages created from the
originating view.
The idea is to temporarily save a copy of the messages in a storage that will
survive to the redirection, and then reinject those messages to the JSF context
before rendering the destination view.
Attached I have provided with a simple but effective way to achieve this
behaviour.
