Chris Hane commented on JBSEAM-1289:
------------------------------------
I have attached two files that are modified to get Trinidad dialogs working.
These files work with Seam 1.2.1patch1, MyFaces 1.x and JBoss 4.0.4. The MyActionListener
is a subclass of a MyFaces class (so changes will be needed in order to work with the Sun
JSF RI).
I have also hardcoded the name of the conversation parameter id (cid) in to the
MyPhaseListener. I believe this is the 1.2.1p1 default.
There is a complete working example at:
http://sourceforge.net/project/showfiles.php?group_id=189858
See the TestApp download
The large files size is due to the included libraries. There are only a 10 small files to
look at:
- MyActionListener
- MyPhaseListener
- faces-config.xml
- 4 .xthml (index / main / main2 / chooseNumber_dlg)
- 3 SLSB (Main, DialogManager, ChooseNumber)

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);
}
