jsf - <f:ajax> doesn't work on PrimeFaces component -

i trying use onchange event of selectonemenu, doesn't work , component not displayed when add onchange attribue.

can tell me how can handle onchange event of <p:selectonemenu>?

here view:

<p:selectonemenu id="service" filtermatchmode="startswith">       <f:selectitem itemlabel="selectionner un service : "  />       <f:selectitems value="#{newopprogramme.listesevice}" var="service" itemvalue="#{service.serviceid}" itemlabel="#{service.servicenom}"/>     <f:ajax event="change" execute="@this" listener="#{newopprogramme.servicechange()}" render="nomcdp"/> </p:selectonemenu> 

and here <f:ajax listener> method in request scoped bean:

public void servicechange() {     system.out.println("change"); } 

when change menu, however, nothing been printed.

how caused , how can solve it?

first of all, onchange wrong event name. it's change. secondly, if intend call html attribute name, onchange wrong attribute name. it's onchange.

coming concrete problem; standard jsf <f:ajax> not compatible primefaces components. should using primefaces own <p:ajax> instead.

<p:selectonemenu ...>     ...     <p:ajax listener="#{newopprogramme.servicechange()}" update="nomcdp" /> </p:selectonemenu> 

note omitted event , process attributes. both have right default value of valuechange , @this respectively.
