After I updated my application to Seam 2.0.2.GA I run into the following problem:

16:35:55,862 ERROR [lifecycle] JSF1054: (Phase ID: PROCESS_VALIDATIONS 3, View ID: /address/subject.xhtml) Exception thrown during phase execution: javax.faces.event.PhaseEvent[source=com.sun.faces.lifecycle.LifecycleImpl@196f6]
16:35:55,864 ERROR [ExceptionFilter] handling uncaught exception

In the view I have the following:

<h:outputLabel for="subjectDepartmentDecoration" value="Abteilung:"/>
<s:decorate id="subjectDepartmentDecoration">
  <a4j:outputPanel layout="block">                  
    <h:selectOneMenu value="#{subject.addrDepartment}" id="subjectDepartmentSelection">
      <s:selectItems value="#{allDepartmentsOfCompany}" var="dep" label="#{dep.name}"/> 
      <s:convertEntity/>
    </h:selectOneMenu>
  </a4j:outputPanel>
</s:decorate>

Does anyone have an idea what's going on here?
