    Hi,

    depending on where you put the bean:

    componentSession - depending on HttpSession timeout.

    profile/context - subject to garbage collection & portal component cleanup.

    Hi!

    I had the same Problem using "Context" and "application" scope. I also tried "Profile", "Request" and "Session".

    "Session" worked best => nothing gets lost !

    IPortalComponentSession componentSession = componentRequest.getComponentSession();

    STORE:

    componentSession.putValue("mybean", mybean);

    GET:

    mybean = (BeanClass)componentSession.getValue("mybean");

    In the JSP:

    <jsp:useBean id="mybean" scope="session" class="com.ecs.cfr.bean.BeanClass" />

    Regards Christian

    Hi all,

    SAP has released note 802015 about the different ways how to store data of a portal component. Please have a look.

    Best regards,
