title: ajax event not working
body: <p>I have a form that should appear when the checkbox is true. This won't work. weird thing is : I did exactly the same on another page and there it works. Also when using another boolean property in the backing bean itself it works.</p>
  
  <pre><code>&lt;div class="field"&gt;
      &lt;p:outputLabel for="company" value="Company" /&gt;
      &lt;p:selectBooleanCheckbox id="company" value="#{participantDetailBean.participant.isCompany}"&gt;
          &lt;p:ajax event="change" update="companyFields"/&gt;
      &lt;/p:selectBooleanCheckbox&gt;
  &lt;/div&gt;
  &lt;p:outputPanel id="companyFields"&gt;
      &lt;div class="field"&gt;
          &lt;p:outputLabel for="companyname" value="Company name" rendered="#{participantDetailBean.participant.isCompany}" /&gt;
          &lt;p:inputText id="companyname" value="#{participantDetailBean.participant.companyName}" rendered="#{participantDetailBean.participant.isCompany}" /&gt;
      &lt;/div&gt;
  
      &lt;div class="field"&gt;
          &lt;p:outputLabel for="companyform" value="Company form" rendered="#{participantDetailBean.participant.isCompany}" /&gt;
          &lt;p:inputText id="companyform" value="#{participantDetailBean.participant.companyForm}" rendered="#{participantDetailBean.participant.isCompany}" /&gt;
      &lt;/div&gt;
  
      &lt;div class="field"&gt;
          &lt;p:outputLabel for="companynumber" value="Company number" rendered="#{participantDetailBean.participant.isCompany}" /&gt;
          &lt;p:inputMask id="companynumber" value="#{participantDetailBean.participant.companyNumber}" mask="aa 9999.999.999" rendered="#{participantDetailBean.participant.isCompany}" /&gt;
      &lt;/div&gt;
  &lt;/p:outputPanel&gt;
  </code></pre>
