Chris Rudd commented on JBSEAM-1296:
------------------------------------

The point is that from the navigation rules because of a certain outcome i want to redirect to a new location and NOT propagate the conversation. I documented a situation in the original issue notes. Procesing is complete, 

Im not sure what you are refering to with the before-redirect attribute. Also the page parameters are passed via the URL,. so technically the conversation is not needed. And in this case I dont WANT the conversation as I want the place im redirecting to to start out without a conversation, as issues arise when the same conversation is used over and over again (conversational components build up from previous conversations that are not needed in the current conversation, but exist as there is no mechanizm to "clear out" old conversational components other than truly ending the conversation and starting another one.

>         </rule>

> </page>
> Side note : 
> The reason for needing to control the propagation in the circumstance above is so that the target view (/viewDocument.xhtml) can start with a new clean conversation. The redirect mechanism delays the end of the conversation untill it gets to the redirected to view, but I dont want that conv to be used. The before-redirect attribute doesnt work in this case as the redirect url needs to include data from the existing conversation (page parameters). I use the same scenario in other places via s:link/s:button but I cannot do this here as its dependent on the outcome not what link/button I pressed
