sorting doen't work in scrollableDataTable with dynamic colu

[munichgrizzley]

Hi,

I try to get sorting of columns working in a scrollableDataTable with dynamic columns. But so far with out success. The relevant part of the jsp is

<rich:scrollableDataTable value="#{hello.wines}" var="w" styleClass="table"
 headerClass="tableHeader" rowClasses="evenRow,oddRow" height="300px" width="100%" rows="20"
 sortMode="single">
 <rich:columns value="#{hello.fields}" var="field" sortBy="#{w[field.property]}">
 <f:facet name="header"><h:outputText value="#{field.title}" /></f:facet>
 <h:outputText value="#{w[field.property]}" />
 </rich:columns>
 </rich:scrollableDataTable>

If I click on a column I get the error message

javax.el.PropertyNotFoundException: Property 'rf1' not found on type com.gpc.webprototype.domain.Wine
 javax.el.BeanELResolver$BeanProperties.get(BeanELResolver.java:193)

If I use sortExpression instead of sortBy, I get the error message
