I'm trying to use drag and drop with a rich:scrollableDataTable. I frequently get this message when I try to drag a row from the table:

java.io.NotSerializableException: org.richfaces.model.selection.SelectionRange

This only happens if I select the row by clicking it then try to drag it. I think that the DND is trying to drag a SelectionRange instead of the actual component in the row.

How do I prevent this error?

Here is the table code:

<rich:scrollableDataTable
 id="available"
 value="#{selector.available}"
 var='av' sortMode='multi'
 rows='10' height='100px'
 frozenColCount='1'>
 <rich:column>
 <f:facet name='header'>
 <h:outputText value='Available' />
 </f:facet>
 <a4j:outputPanel>
 <rich:dragSupport dragIndicator=":indicator"
 dragType="AVAILABLE" dragValue="#{av}">
 <rich:dndParam name="label" value="#{av.english}" />
 </rich:dragSupport>
 <h:outputText value="#{av.english}" />
 </a4j:outputPanel>
 </rich:column>
</rich:scrollableDataTable>

<rich:dropSupport
 acceptedTypes='AVAILABLE' dropValue='AVAILABLE'
 dropListener='#{selector.selectedDropListener}'
 reRender='available,selected' />
