Subject [jira] Updated: (MYFACES-403) Use a PhaseListener to reinject FacesMessages lost during a redirection to the JSF context
Date Mon, 08 Aug 2005 13:21:37 GMT
     [ http://issues.apache.org/jira/browse/MYFACES-403?page=all ]

Enrique Medina Montenegro updated MYFACES-403:
----------------------------------------------

    Attachment: FacesMessageListener.java

This listener must be extended in order to provide the mechanisms to get and set the list
of messages from a temporary storage, e.g. the HttpSession

Then it has to be registered in the faces-config.xml file:

	<lifecycle>
		<phase-listener>
			com.deltar.taller.web.bean.FacesMessageListener
		</phase-listener>
	</lifecycle>

> 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.
