in http://www.jboss.com/index.html?module=bb&op=viewtopic&t=122372, there is mention of scrollabledatatable headers being screwed up on reRender.
The recommended fix was to move to 3.2.0-SNAPSHOT. I did and it is still happening. In F.F., the dheader vanishes after a rerender and in I.E., it is there for a second, then is replaced with parrallel lines that are on top of each other across the table header area. The actual table is getting repopulated correctly
env: jboss4.2.0, Richfaces 3.2.0-SNAPSHOT, SEAM 2.0.0.GA

<h:form>
 <table class="casedetail">
.
.

 <tr>
 <td
 class="tag"
 colspan="4"
 align="center">
 <a4j:commandButton
 value="Redisplay Grid"
 action="#{CASELISTFORM.getCaseListData('CUSTOM')}"
 reRender="casetable" /></td>
 </tr>

 </table>
</h:form>
<h:form>
.
.
 <rich:scrollableDataTable
 id="casetable"
 rows="50"
 value="#{caseList}"
 var="case"
 sortMode="single"
 width="800px"
 height="600px"
 selection="#{CASELISTFORM.selection}"
 rowClasses="even-row, odd-row">

.

 </rich:scrollableDataTable>
</h:form>

Is there a workaround for this?- it is occuring in my app in the above location and in a rerender of a modalpanel that contains a scrollabledatatable.
