Hi I have a Page on which I am have to execute a long running task when a form is submitted. This is what I do
1. I have a transient FutureTask member variable in the page 2. On submit of the form i create a callable and instantiate the FutureTask 3. I start the AbstractAjaxTimerBehaviour which keeps checking if the FutureTask is done before it can update a panel in the page with the result of the execution. - This works fine when I'm on the same page - Now if I submit the form and while the AbstractAjaxTimerBehaviour is still polling I open the same page *in a new tab* *within the same session* then the reference to the FutureTask in the first page (previous tab) becomes null. I couldn't find any solution to this problem. Any help would be greatly appreciated. Thanks -Lina
