sessionScope variables are null

Question

I am trying to get handle on sessionScope variables but thay are not being recognized immediately on the next page. Sorry for lots of info here but any ideas?

First XCpage has a customControl named ccMultipleLoadHandlers. In the custom control there is a repeat control which gets a handle on data in a Domino view and the last column is a link which sets several sessionScope variables and opens another XPage. Here is the code for the link.

                                        <xp:link
                                            escape="true"
                                            id="link3"
                                            text="${langBean.labelEdit}"
                                            value="/RemanRental.xsp">

The opened XPage has a custom control named ccRentMultLoadHandleDisplay which has code in the afterPageLoad event. That code is:

}
}

The problem is that the sessionsScope variables are null but if I reload the page they are there and code properly sets fields

Here are messages that are displayed in the Debug Tool Bar

09:29:40 3. funct=

09:29:40 >>>> sessionScope.rentDisplay is null <<<<

09:29:40 >>>> before page load: sessionScope.rentDisplay is null <<<<

And here are the recorded sessionScoped variables:

XXXXXXXX caitm: 2362656

calitm: 25G-FDS-1200

rentDisplay: MultLoadHandDisplay

rentView: Multiple Load Handlers

XXXXXXXX

The resulted page is: If I reload the pae second page, then the sessionScope variables are recognized Resulted page is:

I created a custom control named reoladPage, then added client side set timeout script block per Knut Herrmann suggestion in this posting: Need to reload an XPage after a few seconds. I added the custom control to my XPage. Problem solved.
