Jsf datatable mit hibernate

Question

hi, kann jemand mich helfen? ich habe fast das selbe Problem wie
http://www.tutorials.de/forum/j2ee/264251-hibernate-collection-mit-list.html
habe eine bidirektionale many-to-one assoziation
employee *-1 division
benutze jsf(myfaces1.1 here nicht so relevant) und hibernate3.1core
in View divisionList.jsp :
<h:column>
                       <f:facet name="header">
                            <h:outputText value="Employees"/>
                       </f:facet>
                       <h:dataTable id="divEmployee"
                                         value="#{division.employees}"
                                         var="employee">
                              <h:column>
                                  <h:outputText value="#{employee.nickname}"></h:outputText>   //fehlerort, kann nickname nicht kennen
                              </h:column>
                       </h:dataTable>
                    </h:column>als ich die View aufrufen, kommt die fehlermeldung :
javax.faces.el.PropertyNotFoundException: Bean: org.hibernate.collection.PersistentSet, property: nickname
     org.apache.myfaces.el.PropertyResolverImpl.getPropertyDescriptor(PropertyResolverImpl.java:500)
     org.apache.myfaces.el.PropertyResolverImpl.getPropertyDescriptor(PropertyResolverImpl.java:472)
     org.apache.myfaces.el.PropertyResolverImpl.getProperty(PropertyResolverImpl.java:436)
     org.apache.myfaces.el.PropertyResolverImpl.getValue(PropertyResolverImpl.java:85)
     org.apache.myfaces.el.ELParserHelper$MyPropertySuffix.evaluate(ELParserHelper.java:535)
     org.apache.commons.el.ComplexValue.evaluate(ComplexValue.java:145)
     org.apache.myfaces.el.ValueBindingImpl.getValue(ValueBindingImpl.java:386)
mapping in Employee.hbm.xml :
<many-to-one name="division" class="....hibernate.Division" fetch="select" lazy="false">
                 <column name="EMP_DIVISION" />
             </many-to-one>in Division.hbm.xml :
<set name="employees" inverse="true">
            <key>
                <column name="EMP_DIVISION" />
            </key>
            <one-to-many class=".....hibernate.Employee" />
        </set>--------------------------------------------------------------------------------------------------------------------
in beans: in Division.java
private Set employees = new HashSet(0);in employee.java einfach :
private Division division;

i have not posted the completely code and omitted the getter and setter.

1. You can try extended data table from tomahawk, it can work with Sets.
2. switch from Set to List on my hibernate entities associations.
