Implementation of Popup dialogs in JSF

Question

Sir,
We implemented popup windows using dialog:popupwindow from a jsf page.
From a page a pop up is called . It has 2 buttons , Yes and No. On clicking yes i show go to another page. If I click No i should come back to the same page itself.
We implemented it in this way.
From an action button of a page a method is called. In that action method a pop up dialog is called. In the action button we have given a return listerner binding. Pop up window has 2 buttons. Any action will take me to the return listerner method. Here i can do any actions. If i click "Yes" in the popup, I have to do some functionality. But after my operations i want to go to another page which shows i have been successful in my work. If i click "No", i want to remain in my page itself.
How can i implement this.
plzzzz help.
with regards,
Anila.

Hi,
you don't need to programmatically launch the dialog, you can also use the declarative way to do so. The return listener is important thouh. Both buttons yes/no should call
AdfFacesContext.getCurrentInstane().returnFromDialog();
this method takes 2 arguments that define return values. The first argument is an Object, the second a HashMap. Both arguments are optional and can be null.
If you use the first then the call is
AdfFacesContext.getCurrentInstane().returnFromDialog("yes",null);
In the return listener you check for the returned object and compare it to "yes". If this is yes, then you can call either
facesContext.getExternalContext().redirect("/faces/te_page_to_go.jsp");
or
facesContext.getViewRoot().setViewId("new_view_id");
then call
facesContext.responseComplete();
