Row count in filtered DataTable

[chinchilla]

How can I get the number of results after filtering in a paged DataTable in PrimeFaces?

Code: Select all

<p:dataTable id="tbl" var="x" value="#{dbBean.xSorted}" paginator="true" rows="20">
    <p:column sortBy="#{x.id}" filterBy="#{x.id}" filterMatchMode="exact">
        <f:facet name="header">
            <h:outputText value="ID" />
        </f:facet>
        <h:outputText value="#{x.id}" />
    </p:column>
</p:dataTable>

The table has ~20 columns which can be sorted and filtered.
