Question

I need to pass some parameters (id in my example) to f:ajax listener method, but i don’t know how. Anybody help ?

<h:form>
    <!-- need to pass id value -->
    <input type="hidden" name="id" id="id" value="#{id}"/>

    <h:selectOneMenu value="#{visibility}">
      <f:selectItems value="#{visibilities}" var="e" itemValue="#{e}" itemLabel="#{e.name}" />
      <f:ajax event="valueChange" render="@form" execute="@form" listener="#{bean.updateVisibility}" />         
    </h:selectOneMenu>
</h:form>

Bean:

class Bean {
    Integer id;

    public void setId() {
       this.id = id;
    }

    public void updateVisibility(AjaxBehaviorEvent event) { 
       // passed id
       log.debug(id);
    }
}

Passing params to f:ajax is done by:

<f:ajax event="valueChange" render="@form" execute="@form" listener="#{bean.updateVisibility}">
    <f:param value="#{id}" name="myId">
</f:ajax>
