Java 与dataScroller在同一页上使用两个DataTable时出错

我有两个rich:datatables，每个表都有一个rich-data:scroller

<rich:dataTable id="mainTable"
                summary="#{i18n['br.com.petrobras.crud.datatable.summary']}"
                styleClass="TableGrid"
                value="#{bean1.objectDataModel}"
                var="historicoItem"
                first="#{bean1.jsfPagination.firstItemIndex}"
                rows="#{bean1.jsfPagination.pageSize}">
</rich:dataTable>

<rich:dataScroller id="**scrollerHistorico**" styleClass="Pagination"
                   for="mainTable" maxPages="1" fastControls="hide"
                   renderIfSinglePage="false"
                   page="#{bean1.jsfPagination.currentPageForView}">

</rich:dataScroller>

---

这样做的影响是，在操作（和日志消息）之后，所有数据都丢失了参考ID。

我找到了这个问题的答案

只需要创建一个

h:panelGrid

在每个dataTable+dataScroller中

不要问为什么会这样

<rich:dataTable id="anexoGridId"
                summary="#{i18n['br.com.petrobras.crud.datatable.summary']}"
                styleClass="TableGrid"
                value="#{bean2.objectDataModel}"
                var="anexoVar"
                first="#{bean2.jsfPagination.firstItemIndex}"
                rows="#{bean2.jsfPagination.pageSize}">
</rich:dataTable>

<rich:dataScroller id="**scrollerAnexoTratamentoControle**" styleClass="Pagination"
                   for="anexoGridId" maxPages="1" fastControls="hide"
                   renderIfSinglePage="false"
                   page="#{bean2.jsfPagination.currentPageForView}">
</rich:dataScroller>
