冰面两次显示分页器

Question

在使用icefaces（1.8.2）的旧系统中，我有一张桌子。通常在这张桌子下面我有分页器。现在，我希望同一分页器不仅显示在表格的底部，而且显示在顶部。 我有一个下拉菜单，从中可以选择“ rowsPerPage”。当前值存储在控制器中。当我想导航到下一页/上一页时，我完全没有问题。当我想从顶部分页器更改行时，就会出现问题。当我更改值时，将调用设置器并将其设置为控制器，但随后也会调用底部的设置器并将其设置为先前的值。因此，最后我无法从顶部分页器更改它。我不知道如何防止第二个二传手被叫来或以某种方式强制刷新。

<ice:dataPaginator id="test" for="stakeholdersList" paginator="true" rowsCountVar="rowsCount" firstRowIndexVar="firstRowIndex" paginatorMaxPages="5" lastRowIndexVar="lastRowIndex" style="width: 140px; float:left;">
