We have a problem with inter-portlets communication (in particular with portlets published in different portal pages). In details, we want to share one or more parameters (for example an ID) between portal-pages that contain portlets deployed in different war application. We tried with public render parameters but the scope of this specific is limited in the portal-page. Moreover, we tried also to pass a parameter between pages with the event (defined in JSR 286) but the scope of an event is also only inner the portal page. So we tried with aliases but doesn't work to.

Is possible that the different public render parameters across the different application (and portal pages) contain the same value. We also cannot use session because portlets are in different war files.

The problem we need to solve is to allow portlets deployed in different war files to talk each other also whether they are in different portal pages.
