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.
