Something like:


  | 
  | <rich:datatable value="#{datamodel}" var="var">
  |   <rich:column>
  |     <f:facet name="header">Category</f:facet>
  |     <h:selectOneMenu value="#{var.category_id}"  converter="#{converters.myConverter}" />
  |      <s:selectItems value="#{categoryList}" var="cat" label="#{cat.name}"/>
  |     </h:selectOneMenu>
  |   </rich:column>
  | </rich:datatable>
  | 
  | 

Most likely you will want to use <s:convertEntity/> rather that a custom converter, if however you actually want to set the category_id property explicitly (i.e. you are not using hibernate to map the one to many relationship) then you will need to write a converter to convert between the Category entity and it's id, look in the docs for an example.
