[jira] Closed: (MYFACES-259) datatable, datascroller problem with mbean in session scope

---------------------------------------

    Resolution: Won't Fix

I see the problem but I don´t see a way to solve it.

Try to set the first attribute of the datatable to a meaningfull value after you have changed the rowcount of your datamodel. Neither datatable nor datascroller are able to define what a meaningfull value is as it depends IMO on your business case.

> I have a MBean in session scope, which holds the data for the datatable. 
> The scroller for the table works fine, when I use it once or the rowCount of data never changes. But I get in trouble when I change the page of the scroller and change the rowCount.
> Example:
> 1. datatable has 100 rows, scroller shows 10 rows
> 2. I jump to page 5
> ... everything is fine
> After this the data changes ... the datatable has now 5 rows
> And now the problem comes out: The pageIndex of the scrollerComponent is still on page 5 ... and ... there is no data. When I jump to page 1 manually (by rewind-button) the data shows up on the first page.
> I tried all the examples with this combination and got allways the same situation. So, I think it could be a bug ...
