Hi,

I have this code:

<h:panelGroup>
  <h:selectBooleanCheckbox
      id="quarterChose"
      onclick="changeCheckBox();"
      value="#{user.quarterChose}">
  </h:selectBooleanCheckbox>
</h:panelGroup>
<h:panelGroup>
  <t:selectOneMenu id="quarterDropDownId" 
      value="#{user.selectedQuarter}">
      <f:selectItems
        value="#{user.quarters}" />
  </t:selectOneMenu>
</h:panelGroup>

in javascript when the checkbox is deselected the select field is disabled.
But when the select fiedl is disabled and the form is processed server-side
an error message is shown. I think the field's value is not sent anymore.

I want to try to implement this behavior server-side in the bean code with
the help of the f:valueChangeListener.
Can someone provide me some code which shows me how can I change the
appeareace of one component (e.g. from disabled="false" to disabled="true").
