    selectBooleanCheckbox and dataScroller

    Fabrizio Boco Newbie

      Hi,

      I have a dataTable that uses a dataScroller and selectBooleanCheckbox.

      First problem is that selected items get deselectd when I move from one page to the other.

      So I tryed to manage selected items myself. Second problem is that when I move from one page to the other the findAll function is called but selections is empty (see attached code).

      Please help me!

      Thank you

      Regards

      Fab.
