> Seam does not automatically support Trinidad's dialog feature in terms of propagating long running conversations to the dialog window.  
> Forum User dajevtic has provided a custom phase listener and action listener to enable propagation but it requires a specific naming convention for the dialog page.  It would be nice to enable support directly using standard Seam notation like the s:conversationPropagation tag or @Begin(join = true)
> Here are the relevant phase listener and action listener
> *Phase Listener*
> 	private static final String CONVERSATION_ID_SESSION_PARAMETER = "conversationId";
> 	
> 	private Map createParameterMapForConversationRestore(String conversationId) {
> 		Map paramterMap = new Hashtable();
> 		paramterMap.put(CONVERSATION_ID_SESSION_PARAMETER, conversationId);
> 		return paramterMap;
> 	}
> 	
> 	private void restoreConversation(Context context) {
> 		if (context.isSet(CONVERSATION_ID_SESSION_PARAMETER)) {
> 			String convId = context.get(CONVERSATION_ID_SESSION_PARAMETER).toString();
> 			Manager.instance().restoreConversation(createParameterMapForConversationRestore(convId));
> 			context.remove(CONVERSATION_ID_SESSION_PARAMETER);		
> 		}
> 	}
> 	
> 	public void afterPhase(PhaseEvent event) {
> 		try {
> 			if (event.getPhaseId().equals(PhaseId.RESTORE_VIEW)) {
> 				UIViewRoot root = event.getFacesContext().getViewRoot();
> 				if (root != null) {
> 					String viewId = root.getViewId();
> 					if ((viewId != null) && viewId.endsWith("_dlg.jspx")) {
> 						restoreConversation(Contexts.getSessionContext());
> 					}
> 				}
> 			} else {
> 				log.info("after " + event.getPhaseId());
> 			}
> 		} catch (Exception e) {
> 			log.error("Could not restore Seam conversation", e);
> 		}
> 	}
> *Action Listener*
> 	public void processAction(ActionEvent actionEvent)
> 			throws AbortProcessingException {
> 		if (actionEvent.getComponent() instanceof CoreCommandLink) {
> 			CoreCommandLink link = (CoreCommandLink)actionEvent.getComponent();
> 			if (link.isUseWindow()) {
> 				Contexts.getSessionContext().set("conversationId", Manager.instance().getCurrentConversationId());
> 			}
> 		}
> 		super.processAction(actionEvent);
> 	}
