Refresh iViews problem....

Question

Hi,
I am getting a serious problem under EP 6.0.
Lets say that we have 2 browsers opened with the same page. In this page, we have an iView.
If I run the iView on Page1, I display the result and everything works fine.
If I do a refresh on Page 2, I get the result displayed in Page1.
It means, that my iView cannot serve for multi users...because there is a refreshing problem.
The problem may come from my static variables defined in my DynPage class....
Can someone help ?
Thanks.

Hi David,
I think I have understood your problem... In thread
Table navigate and data persistence problem
you will find a similar issue.
As you already found out, the problem lies in storing persistence data in the class itself as new instances will be generated all the time.
Your solution to this should be to write a bean (which is basically an ordinary Java class used for storing data, such as a complex data type in other languages) and store all your persistence data in there. Then, store the bean in the user's session and read in back out whenever you need the data. A code example for this follows...
// writing persistence data in a user's session
// assimung that we are somewhere inside a class that extends "DynPage"
IPortalCompoonentRequest req = (IPortalCompoonentRequest)this.getRequest();
IPortalComponentSession session = (IPortalComponentSession )req.getComponentSession();
session.putValue("myFirstBean", bean); // note: bean is an instance of your custom bean class
// reading persistence data stored in a user's session
IPortalCompoonentRequest req = (IPortalCompoonentRequest)this.getRequest();
IPortalComponentSession session = (IPortalComponentSession )req.getComponentSession();
MyFirstBean bean  = (MyFirstBean)session.getValue("myFirstBean");
Hope this could clearify some things,
