[jboss-user] [JBoss Seam] - seam tries tio create a seam component from a class which is
using seam 2.0 RC1
In a seam component, we are using Hibernate to "get" an instance of a persistent
instance which is not a seam componnent and we receive an
"IllegalArgumentException" .
It seems that, after Hibernate perfoemed the sql select, seam tries to "build"
a seam component from a class which is *not* a seam component
Is this a bug? is this a configuration problem?
The "Utilisateur" class si a plain POJO... (We do't use EJB3..)
Also, we use <core:init transaction-management-enabled="false" /> in
componente.xml

| @Scope(ScopeType.APPLICATION)

UtilisateurManager {

|
| @Transactional(TransactionPropagationType.REQUIRED)
| public Utilisateur obtenirUtilisateurParCodeUsager(String codeUsager) {
| return (Utilisateur) sessionHibernate.get(Utilisateur.class,
codeUsager.toUpperCase());
| }
