Problem with nested dataTables

[m.schuetz]

Hi,

I have a problem using nested dataTables. Following code does not work correctly:

 <h:dataTable value="#{companies}" var="aCompany"
 rendered="#{companies.rowCount > 0 }" binding="#{contracts}">
 <h:column>
 <f:facet name="header">
 <h:outputText value="Unternehmen" />
 </f:facet>
 <h:outputText value="#{aCompany.name}" />
 </h:column>
 <h:column>
 <f:facet name="header">
 <h:outputText value="Bereiche" />
 </f:facet>
 <h:dataTable value="#{aCompany.contracts}" var="aContract">
 <h:column>
 <h:outputText value="#{aContract}" />
 </h:column>
 </h:dataTable>
 </h:column>
 <h:column>
 <h:commandButton action="#{manager.bla}" value="Bearbeiten" />
 </h:column>
 </h:dataTable>

Bean:

@DataModel
 private ArrayList<CompanyEntity> companies;

 @DataModelSelection
 private CompanyEntity selectedCompany;

The Error

/user/showAllCompanies.xhtml @38,51 value="#{aContract.scope}": Bean: org.hibernate.collection.PersistentSet, property: scope

What i get is a list of contractEntititis but not the each Entity.

When Is assign the second dataTable an own Model, everything works fine - but it does not work in teh above example, because all is dynamically generated.

I have neither find anything about that in the documentation nor in the examples.

Do you have an idea?
