The following limitation applies to built-in filtering/sorting for rich:dataTable component: expressions can refer only to the variable declared as "var" attribute. Another variables, e.g. "rowKeyVar" are not supported.

Examples.

Supported case:

		<rich:dataTable var="item">
			<rich:column sortBy="#{item}">
			...
			</rich:column>
		</rich:dataTable>

Not supported case:

		<rich:dataTable rowKeyVar="rkv">
			<rich:column sortBy="#{rkv}">
			...
			</rich:column>
		</rich:dataTable>
