I solved the problem using JQuery to scroll to the position, instead of use scrollToY function of jScrollPane. So the code changed from this:
componente.adicionarListenerScroll = function () {
$('.ui-datatable-scrollable-body').jScrollPane();
$('.ui-datatable-scrollable-body').data('jsp').scrollToY(componente.posicao);
$('.ui-datatable-scrollable-body').bind('jsp-scroll-y', componente.atualizarElementos);
}
to this:
componente.adicionarListenerScroll = function () {
$('.ui-datatable-scrollable-body').scrollTop(componente.posicao);
$('.ui-datatable-scrollable-body').jScrollPane();
$('.ui-datatable-scrollable-body').bind('jsp-scroll-y', componente.atualizarElementos);
}
