[jboss-user] [JBoss Seam] - Problem with selectManyCheckbox and EntityConverter

[valeriopp]

Hello,

I have: my .xhtml like:


  |  	   
  | <h:selectManyCheckbox value="#{AutorizzatiFoManager.selezionati}" layout="pageDirection" >
  |   <si:selectItems value="#{autorizzati}" var="fornitore" label="#{fornitore.nomeFornitore} - #{fornitore.messaggio}" /> 
  |   <ec:convertEntity entityClass="org.jboss.seam.example.registration.Fornitore" /> 
  | </h:selectManyCheckbox>	
  | 
  | 

and in the AutorizzatiFoManager class:


  |    @DataModel
  |    private List<Fornitore> autorizzati;
  |    
  |    @DataModelSelection                                                                  
  |    @Out(required=false)                                                                
  |    private Fornitore tempautorizzato; 
  |    
  |    @OneToMany 
  |    @Out (required=false)
  |    private List<Fornitore> selezionati;
  | 
  | 

Note that the OneToMany List selezionati is a member in the bean class AutorizzatiFoManager (not in an Entity). Is that a problem?

my persistence.xml:

  |          <property name="jboss.entity.manager.factory.jndi.name" value="java:/selectItemsEntityManagerFactory"/>
  |          <property name="jboss.entity.manager.jndi.name" value="java:/selectItemsEntityManager"/>
  | 

my components.xml:

  | 	<core:managed-persistence-context name="entityManager" persistence-unit-jndi-name="java:/selectItemsEntityManagerFactory"/>
  | 

Now it shows the list of Fornitore but when I try to check one or more Fornitore, the error is:
