If I have two portlets on a page (same portlets and instances as defined in *-object-xml) in two different "windows", their sessions get mixed before both portlets are "used" (ie. called with an url that sends request to a specific portlet on the page). The portlet contains: | System.out.println("###"); | System.out.println("request: "+rRequest.getParameter("id")); | System.out.println("session: "+rRequest.getPortletSession().getAttribute("id", PortletSession.PORTLET_SCOPE)); | if ( rRequest.getParameter("id")!=null) { | rRequest.getPortletSession().setAttribute("id", rRequest.getParameter("id"), PortletSession.PORTLET_SCOPE); | } | When I first access the page with two of these portlets I get the following (no query parameters), everything normal: 23:46:35,093 INFO [STDOUT] ### | 23:46:35,093 INFO [STDOUT] request: null | 23:46:35,093 INFO [STDOUT] session: null | 23:46:35,203 INFO [STDOUT] ### | 23:46:35,203 INFO [STDOUT] request: null | 23:46:35,203 INFO [STDOUT] session: null Then I access an url like: /portal/portal/default/TEST/Test1?action=2&id=1 (the page is TEST and one of the windows is Test1). I get: 23:47:20,640 INFO [STDOUT] ### | 23:47:20,640 INFO [STDOUT] request: null | 23:47:20,640 INFO [STDOUT] session: null | 23:47:20,640 INFO [STDOUT] ### | 23:47:20,640 INFO [STDOUT] request: 1 | 23:47:20,640 INFO [STDOUT] session: null I access the same url again: 23:48:09,781 INFO [STDOUT] ### | 23:48:09,781 INFO [STDOUT] request: null | 23:48:09,781 INFO [STDOUT] session: 1 | 23:48:09,796 INFO [STDOUT] ### | 23:48:09,796 INFO [STDOUT] request: 1 | 23:48:09,796 INFO [STDOUT] session: 1 Notice that both sessions show the value "1" even though the session is portlet_scoped. Notice that this starts working correctly after I access the second portlet with: /portal/portal/default/TEST/Test2?action=2&id=2 after which both windows/portlets have their own sessions.
