-------------------------------------------

I am having limited success with the changes you have made.  Most of this may be because of the way I have my enviromnent set up.

my external pages posts to /dt_subscribe.xhtml.  The entries in pages.xml is as follows.


<page view-id="/dt_subscribe.xhtml" >
		<param name="subscribe:title" value="#{subscription.title}"/>
		<param name="subscribe:firstName" value="#{subscription.firstName}"/>
		<param name="subscribe:lastName" value="#{subscription.lastName}"/>
	 	<param name="subscribe:country" value="#{subscription.country}"/>
		<param name="subscribe:postcode" value="#{subscription.postcode}"/>
		<param name="subscribe:email" value="#{subscription.email}"/>
		<param name="subscribe:confirmEmail" value="#{subscription.confirmEmail}"/>     
				
		<action execute="#{subscriber.subscribedt}" if="#{not validation.failed}"/>
		<action execute="#{subscriber.invalid}" if="#{validation.failed}"/>
		
		 <navigation>
			<rule if-outcome="success">
				<redirect view-id="/dtsubscribeConfirm.xhtml"/>
			</rule>
			<rule if-outcome="invalid">
				<redirect view-id="/dtsubscribe.xhtml"/>
			</rule>
		</navigation>
	</page>
---------------END Pages.XML---------------------

The line 
<action execute="#{subscriber.subscribedt}" if="#{not validation.failed}"/>. 

will not work if I use #{validation.succeeded} instead of #{not validation.failed}

and once validation fails and I redirect to another view I do not get validation messages and the fields that are invalid are now blank rather than being auto populated.  All valid fields are re-populated.  The page I redirect to on a failure has a <h:messages globalOnly="true".../> tag.  The #{subscriber.invalid} function just returns "invalid" (my rules were not working properly with out it).  I assume this would work if I just displayed the messages on dt_subscribe.xhtml rather than redirecting???

The dt_subscribe.xhtml file only has 1 line which is the xhtml doctype tag, as I never want this page to be displayed, it should always redirect to another view, a success page if all goes well or a page with a similar form to the external site if validation fails.
