    rich:datascroller out of sync with rich:extendedDataTable

    Drew McLaughlin Newbie

      Hi,

       

      I'm struggling with thedatascroller/extendedDataTable combination, if anyone can point me in the rightdirection it would be very much appreicated!

       

      My application uses anextenedDataTable combined with a datascroller to allow users to searchthrough a list of Service Request objects (this "Service Request"object is just and abstract business concept).

       

      I am using the page attributeof the datascroller to persist the current page in the results set on the usersession. This means that while viewing the Service Requests in theextendedDataTable the user can click on a particular Service Request, navigateaway from the page with the extendedDataTable and view the details of theService Request they have clicked on; then navigate back to the table andstill be on the same page.

       

      This however is not thecase, the dataScroller will rememberwhich page it was at, but the extenededDataTable always reverts to the first page (eventhough the dataScroller is showing page 2 or 3 or 7 or whatever).


      Below is an extract of the dataScroller and the dataTable, many thanks in advance for any help that is offered!

          I am having the same problem.  My current workaround is to take a note of the currently viewed page in my session bean when the user takes a particular action leaving my page, then upon return to my page, the table is initially rendered hidden on page one, and if it is detected that a page other than page 1 was noted in the backing bean, a call is made to the datascroller component on the client side switchToPage method, then after all that the table is unhidden.

           

          Obviously this is a horrible workaround since the table is loaded twice, but at least it is working.  I would really like to hear about a better solution though.
