[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-1289) Conversation Propagation andTrinidad Dialogs

Conversation Propagation andTrinidad Dialogs -------------------------------------------- Key: JBSEAM-1289 URL: http://jira.jboss.com/jira/browse/JBSEAM-1289 Project: JBoss Seam Issue Type: Feature Request Components: JSF Affects Versions: 1.2.1.GA Environment: JBoss 4.0.4GA Reporter: Brian Smith Assigned To: Pete Muir Priority: Minor Attachments: MyActionListener.java, MyPhaseListener.java 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); }
