Unknown reasons for iView timeout in EP 6.0

Question

Hello,
we have recently developed a HR portal application for appraising employees. It is an application using JSP DynPage,connecting to R3 with JCo. The strangest thing about it, is that it works perfectly well on our DEV EP, however on production portal it doesn't. When user tries to save an appraisal form, we get an error. This happens if time of edition of the form exceeds about one minute. If user saves his appraisal quicker,everything is just ok. We don't have this time restriction on DEV EP. User can save his appraisal even after 20 minutes of edition. We were looking for differences in DEV and PRD portals, and found none, except the number of users. We can't figure out, what may be causing this problem. Any ideas? Please help.

Hi Detlev,
I guess the problem boils down to opening a new window in javascript and keeping the session. As I moved all Beans to SessionComponent and thier scope is "session", I can not access them from a new window. This is quite reasonable, but how to walk around ? I tried including the session id in url:
function setTarget(newTarget, newParam, parentRow, who) {
               <% String sessionid = request.getSession().getId(); %>
               var url="<%=selectionBean.componentUrl%>"; 
               var pageUrl = "<%=selectionBean.pageUrl%>";                 
               var connected = "<%=selectionBean.connected%>";
if (connected == 'true') {
//                         var val = window.showModalDialog(url+"?JSESSIONID=<%=sessionid%>&param=note", '', 'dialogHeight: 285px; dialogWidth: 230px; edge: Raised; center: Yes; help: No; resizable: No; status: Yes');                    
                         var wind = window.open(url+"?JSESSIONID=<%=sessionid%>&param=note&parent=" + parentRow + "&who=" + who,"","menubar=0,resizable=0,width=205,height=235,center=1,status=0,scrollbars=0");
                    } else {
//                         var val = window.showModalDialog(url+"?JSESSIONID=<%=sessionid%>&param=note", '', 'dialogHeight: 295px; dialogWidth: 230px; edge: Raised; center: Yes; help: Yes; resizable: No; status: Yes; menubar: Yes');                    
                         var wind = window.open(url+"?JSESSIONID=<%=sessionid%>&param=note&parent=" + parentRow + "&who=" + who,"","menubar=0,resizable=0,width=205,height=235,center=1,status=0,scrollbars=0");                         
But it didn't help. I still get a null pointer exception when I open a new window. Any ideas ?
Best Regards,
