I have a big problem with selectOnMenu in JSF2, i tried to use this component with but not working , i tested also the primefaces example http://www.primefaces.org/showcase/ui/ajax/dropdown.xhtml but without any new result .

i think that i miss some config or filter about ajax in my project or my page.

Here is dropdown code: 

<p:selectOneMenu style="width:300px;"  value="#{parameterBean.name}">
            <f:selectItem itemLabel="Select parameter Type" itemValue="" noSelectionOption="true" />
            <f:selectItems value="#{parameterTypeBean.listParameterTypes}"  var="ptype"     itemValue="#{ptype.id}" itemLabel="#{ptype.name}" />
            <p:ajax listener="#{parameterBean.serviceChange}" event="change" update="pTable" process="@form"/>
        </p:selectOneMenu>

This is my simple actionBean : 

    public void serviceChange() {
    System.out.println("change");
}

Can you help me to resolve this problem ?

remove process="@form" so it would be 

<p:ajax listener="#{parameterBean.serviceChange}" event="change" update="pTable"/>

  • That is the default so leaving it out does not make a difference (at least it should not) http://stackoverflow.com/questions/25339056/understanding-process-and-update-attributes-of-primefaces – Kukeltje Feb 12 '16 at 12:48
  • But most likely with a different signature of the service method. – Kukeltje Feb 13 '16 at 07:34
