I use Seam 2.0.0 . Then I changed to:
  |  <h:selectManyCheckbox value="#{selezione.fornitoriSelezionati}" layout="pageDirection" >
  |    <s:selectItems value="#{AutorizzatiFoManager.autorizzati}" var="fornitore" label="#{fornitore.nomeFornitore} - #{fornitore.messaggio}" /> 
  |    <s:convertEntity entityClass="org.jboss.seam.example.registration.Fornitore"/> 
  |  </h:selectManyCheckbox>	

  | <persistence:managed-persistence-context name="entityManager" auto-create="true"         persistence-unit-jndi-name="java:/epEntityManagerFactory" />
  |  <property name="jboss.entity.manager.factory.jndi.name"
  |                    value="java:/epEntityManagerFactory" /> 

in Selezione.java (the entity class named selezione in the context)

  | @OneToMany 
  |    private List<Fornitore> fornitoriSelezionati;

in AutorizzatiFoManager.java

  |    private List<Fornitore> autorizzati;

I still get the right list, but when i check one or more checkbox, i get a facesmessage:
	j_id96:j_id101: Validation Error: Value is not valid

the html generated code for the SelectManycheckbox is, for example for the third element of the list:

  | <input name="j_id96:j_id101" id="j_id96:j_id101:3" value="3" type="checkbox" checked="checked" /><label for="j_id96:j_id101:3">Third element ....</label>
while before in the value field I had theClassPackage.Fornitore(a)[a coded id]
