Richfaces dataTable工作正常，但ExtendedDataTable不显示数据

我们正在使用Richfaces 4.1.0，我正在尝试使用extendedDataTable。我用dataTable启动（为了简单起见）。下面的代码工作正常，并按照预期在表中显示我的数据。

We are using Richfaces 4.1.0, and I am trying to use an extendedDataTable. I started (for simplicity's sake) with dataTable. The code below works fine, and shows my data in a table, as expected.

<rich:dataTable value="#{recipientBean.recipientList}" var="recipient" selectionMode="none" id="recipientTable">
    <rich:column sortable="false" id="col_1" label="Name">
        <f:facet name="header">
            <h:outputText value="Name" id="name" />
        </f:facet>
        <h:outputText value="#{recipient.name}" id="rec_name" />
    </rich:column>
    <!-- More columns below, removed for post brevity -->
</rich:dataTable>

我们期待大量的记录，所以我们希望表可以滚动。我以为我可以将dataTable更改为extendedDataTable，但是当我这样做时，根本就没有显示任何数据。

We are expecting a large number of records, so we would like the table to be scrollable. I thought that I could just change the dataTable to extendedDataTable, however, when I do that, no data shows up at all.

我刚刚开始检查Chrome中的元素，突然数据显现。所以当我检查元素时，我看到html中的值，但是当页面加载时不显示。

I just started to inspect the element in Chrome, and all of a sudden the data showed up. So when I inspect the element, I see the values in the html, but they don't display when the page loads.

这可能是一个风格问题吗？缺少一个属性（扩展数据表所需的东西，但数据表不需要）？

Could this be a style issue? An attribute that is missing (something that is needed for extendedDataTable, but not needed for dataTable)?

我还缺少什么？

编辑：我有一个richDataTable中的extendedDataTable：tabPanel。当我删除rich：tabPanel它正确显示（但我真的需要tabPanel）。这是一个已知的问题吗？

I do have this extendedDataTable inside a rich:tabPanel. When I remove the rich:tabPanel it displays correctly (but I really need the tabPanel). Is this a known issue?

EDIT2：如果它位于rich：tabPanel的第一个选项卡上，它会正确显示。

It does display correctly if it is on the first tab of the rich:tabPanel.
