I recently came across a need to be able to use the rich:columns tag along with rich:scrollableDataTable. I put it together, and it displays beautifully... until I try to use the sort feature.  When I click the column header to sort, the sorting works fine but all the column headers disappear!  I have tried a number of different things based on the documentation, but I still have the same problem.  I found a few issues in JIRA, specifically issue 6807, https://issues.jboss.org/browse/RF-6807 that describes this problem in great detail.

My project is currently running RF 3.3.3.CR1 with Seam 2.2, which is after the build where this issue was marked as resolved. I even tried updating to 3.3.3.Final, but the problem still seems to exist. Does anyone have a hint on how to make this works, or a working example? Any help is appreciated!

For reference, here is my most recent attempt:

{code:xml}

<rich:scrollableDataTable

    height="300px"

        width="700px"

    id="lookupList"

    rows="40"

    columnClasses="center"

    value="#{lookupBean.lookupList}"

    var="lookupItems"

    sortMode="single"

    rendered="#{!empty lookupBean.lookupList}"

    sortOrder="#{lookupBean.singleSortOrder}"

    selectionMode="none"

>

        <rich:columns

            value="#{lookupBean.getKeys()}"

            var="_column"

            index="_colIndex"

            sortExpression="#{lookupItems.get(_column)}"

            id="lookupCol#{_colIndex}"

        >

            <f:facet name="header" id="header#{_colIndex}">

                <h:outputText value="#{_column}" />

            </f:facet>

            <h:outputText value="#{lookupItems.get(_column)}" />

        </rich:columns>                               

</rich:scrollableDataTable>

{code}
