On selectonemenu change uncheck checkbox?

[Dan Acuff]

I have to uncheck a selectBooleanCheckbox lower down in the form IF it is checked.

So I added the showOnWebAjx id to the reRender shown below.

  <h:selectOneMenu id="estatus" value="#{itemHome.instance.estatus}"
    required="true">
    <f:selectItems id="estatuses"
        value="#{mconsoleContext.ecometryItemStatusCodes}" />
    <a:support event="onchange"
        reRender="showOnWebAjx, ecycleWeeksAjx, orderSizeFoodPoAjx, upcAjx, kitAjx, preOrderAjx, priorityProcessingAjx"
        actionListener="#{itemHome.resetPreOrderAndPriorityProcessingFlag}"
        ajaxSingle="true" />
</h:selectOneMenu>
  

I don't know how to uncheck the box but with the below code I can tell when it is C1 or H1 (2 of the values where we want to uncheck the box, the rest of the time we do nothing)

  <s:decorate id="showOnWebFlagDecoration"
    template="/layout/edit.xhtml">
    <ui:define name="label">#{messages.showOnWebFlag}</ui:define>
    
<a:outputPanel id="showOnWebAjx">
 
<c:if test="#{'C1' eq itemHome.instance.estatus || 'H1' eq itemHome.instance.estatus}">UNCHECK showOnWebFlag!!</c:if>
 
    <h:selectBooleanCheckbox id="showOnWebFlag"
        value="#{itemHome.instance.showOnWebFlag}"/>
 
</a:outputPanel>
 
</s:decorate>
  

The a:outputPanel and c:if test are my additions.

What is the proper / correct way to uncheck that box?

Thank you very much for any help.

I was wondering is this not possible without doing something on the backend?

Help appreciated.

Thanks,
