af:popup, if use panelWindow, the main page will not be inactived, how could make it inactive

[ym feng]

just like use af:dialog.

and, how to do a backing process, while the popup pops up, showing some processing message.
if i use popupFetchListener, i find that the method could be executed just one time.

actually , what's the requirement is:
1,click one button,
2,some business processed, meaning while, a dialog pops up, showing some dynamic processing message.
3,dialog close automatically after process finished.

could anybody help me ?

attribute named 'modal' is used to determine whether main page be active or inactive.
could someone answer the remaining question(s)?

now, i use af:poll to pull from server, which may cause server overload.
any method that managed bean could push it to client, which could make it real time and reduce server's load?
