<h:outputText> inside <c:forEach> doesn't work properly in JBoss Seam

Issue

<h:outputText value="#{data}" /> inside <c:forEach var="data"> refers an instance different from plain #{data}. So my loop doesn't work properly.

When I access the page for the first time, the page will be rendered correctly. But then, after I kick 'Next Page' action that increments begin/end attribures of <c:forEach>, <h:outputText value="#{data}"/> won't change while #{data} will change appropriately.
