Coordination Between Portlets Across Pages - Webcenter 11g

Question

I am trying to create JSR 286 portlets with Webcenter and configure IPC with it. I am trying to connect portlet A with portlet B, with portlet A on page one and portlet B on page two.
After some research I know other containers like Webspere and Liferay can be configured to perform IPC across different pages. http://developers.sun.com/portalserver/reference/techart/jsr286/jsr286_3.html
Does anybody know if this is possible with Webcenter 11g? I was able to get IPC working with Portlet A and Portlet B on the same page.

Hoque,
My tutorial will show how IPC works for portlets on the same page but not over different pages.
There are a few remarks before building such a page flow... Portlets are designed to be independent from the portlet. They shouldn't be tightly coupled with the portal. When you want to communicate over pages, you create tightly coupled portlets which is completly against the basic principles of portlets...
If you want to build a flow like this, you definitly can do this. The easiest way is when both portlets are from the same producer. All portlets from the same producer share the same session which means that you can use this to put values on the producer session.
In order to respect the portlet interopability ideas, you should expose an event instead of navigation to a different page from within the portlet. The event will be triggered by the portal and the portal will navigate to the next page.
By doing this, you don't really have a tight coupling because you just expose an event and the portal decides to navigate to another page upon that event.
