jsf - Using PrimeFaces Global Filter? -


as mentioned in primefaces showcase trying create global filter datatable . there unable understand carstable means, in code fragment 

 <h:form>         <p:datatable var="car" value="#{tablebean.carssmall}"                emptymessage="no cars found given criteria">              <f:facet name="header">                <p:outputpanel>                    <h:outputtext value="search fields:" />                    <p:inputtext id="globalfilter" onkeyup="carstable.filter()" style="width:150px"/>                </p:outputpanel>            </f:facet>

when use my datatableid inplace of carstable iam getting javascript error undefined id.

this looks typo in showcase code display. missing attribute on <p:datatable> component called widgetvar. attribute declares unique javascript identifier client side component. code should show this:

<p:datatable var="car" value="#{tablebean.carssmall}"    widgetvar="carstable" emptymessage="no cars found given criteria"> ...

for reason client side function filter() not declared in pf guide 2.2 under client dom datatable, know there , use it.
