Richfaces DataScroller

[Shaiju scientia]

Hi,
I am using dataScroller for pagination. I have also customized the data model in order to implement a hybrid pagination logic.
My hybrid approach requires to identify which datascroller control button(i.e either next page button or fast forward button) is clicked.Basically when ever the user click on any of the pagination controls, the "walk" method of the datamodel will be invoked.Here I have to identify which control has been clicked by the user.

Any suggestions??

Thanks In Advance
