Parent is not composite component or of type ClientBehaviorHolder on a selection one menu

问题

I am trying to get a second selection method to show up depending on what was selected for the first value. Now i need to do this over 38 times for a form i am making but i want to see if i can get it working for one question first. Here is the code i have so far cut on the jsf page. The values are all the same for the other 38 questions. I just recreated the project and so far the bean is currently empty but i know i should be able to atleast see the form first which is what i am hoping to do for now before i add the values and code.

Remove the f:ajaxs outside of the h:selectOneMenu. h:form is no ClientBehaviourHolder so you can not place a f:ajax there. You just can put them into the h:selectOneMenu.

EDIT: Just remove the f:ajax without the parameters, those which wrap the panelGroups and keep the selectOneMenues:

<h:selectOneMenu value="#{qcFormBean.dlitcStickerValue}">
    <f:selectItem itemValue="P" itemLabel="Pass or Not applicable" />
    <f:selectItem itemValue="M" itemLabel="FAIL-Mechanical" />
    <f:selectItem itemValue="E" itemLabel="FAIL-Electrical" />
    <f:selectItem itemValue="C" itemLabel="FAIL-Cosmetic" />
    <f:selectItem itemValue="S" itemLabel="FAIL-Software" />
    <f:ajax event="change" execute="@this" render="perfbyDlitcSticker" />
</h:selectOneMenu>

EDIT2: Replace the code between </b> and the <br/> before the commandButton with the following code:

<h:panelGroup id="dliSticker">
    <h:selectOneMenu value="#{qcFormBean.dlitcStickerValue}">
      <f:selectItem itemValue="P" itemLabel="Pass or Not applicable" />
      <f:selectItem itemValue="M" itemLabel="FAIL-Mechanical" />
      <f:selectItem itemValue="E" itemLabel="FAIL-Electrical" />
      <f:selectItem itemValue="C" itemLabel="FAIL-Cosmetic" />
      <f:selectItem itemValue="S" itemLabel="FAIL-Software" />
      <f:ajax event="change" execute="@this" render="perfbyDlitcSticker" />
    </h:selectOneMenu>
</h:panelGroup>

<h:panelGroup id="perfbyDlitcSticker">
    <h:selectOneMenu value="#{qcFormBean.stickerFreq}"
    rendered="#{!qcFormBean.dliStickerValue eq  'P'}">
        <f:selectItem itemValue="A" itemLabel="Always" />                
        <f:selectItem itemValue="O" itemLabel="Often" />
        <f:selectItem itemValue="S" itemLabel="Seldom" />                
    </h:selectOneMenu>
</h:panelGroup>

instead of using 'f:ajax' i used instead richfaces 'a4j:ajax' parameter for the xhtml and while now i have a different issue "The web page with the tags wont show up only text." so i can't really tell if i converted to richfaces correctly but here is what i change let me know if i am right or not thank you.
