java.lang.Boolean kann nicht auf javax.faces.model.SelectItem gegossen werden

Question

Ich versuche, eine einfache h zu verwenden: selectOneRadio mit Wahr/Falsch-Werte also hier ist, was ich verwendet:

• Backing Bean:

  private boolean myOption; 
  

• xhtml Seite:

   <h:selectOneRadio id="myOption" value="#{myBean.myOption}"> 
        <f:selectItem itemLabel="Yes" value="#{true}"></f:selectItem> 
        <f:selectItem itemLabel="No" value="#{false}"></f:selectItem> 
       </h:selectOneRadio> 
  

aber wenn das Formular abschicken ich bin immer die Ausnahme:

java.lang.ClassCastException: java.lang.Boolean cannot be cast to javax.faces.model.SelectItem
