I need a mechanism to synchronize the inner dataTable with the outer one.

value="#{assortmentCategories}">

  |                                     <h:outputLink value="">
  |                                             <h:outputText 
value="#{category.description}" />
  |                                     </h:outputLink>
  |                             </h:column>
  |                     </h:dataTable>
  |             </h:column>
  |     </h:dataTable>

The list assortmentCategories is depended from the current element in the 
assortments list. I need a mechanism to update it.
