ClassCastException - FullTextHibernateSessionProxy
Hi,
my enviroments:
JBoss AS 4.2.0.GA
Seam 2.0.0.BETA1(CVS)
Seam gen-generated project
When DetachedCriteria#getExecutableCriteria in the following code is invoked,
"java.lang.ClassCastException: org.jboss.seam.persistence.FullTextHibernateSessionProxy" is thrown.
This code worked with Seam1.3.0.ALPHA.
@Name("criteriaTesting")
@Scope(ScopeType.CONVERSATION)
public class CriteriaTestingBean implements Serializable {
@In
private EntityManager entityManager;
private Integer minAge;
private Integer maxAge;
@Out(required=false)
private List<Member> members;
public void setMinAge(Integer minAge) {
this.minAge = minAge;
}
public void setMaxAge(Integer maxAge) {
this.maxAge = maxAge;
}
public void search() {
Session session = (Session) entityManager.getDelegate();
DetachedCriteria crit = DetachedCriteria.forClass(Member.class);
if (minAge != null) {
crit.add( ge("age", minAge) );
}
if (maxAge != null) {
crit.add( le("age", maxAge) );
}
members = crit.getExecutableCriteria(session).list();
}
}
The following: stack trace

The following(not DetachedCriteria version) works fine with Seam 2.0.0.BETA1.
public void search() {
Session session = (Session) entityManager.getDelegate();
Criteria crit = session.createCriteria(Member.class);
if (minAge != null) {
crit.add( ge("age", minAge) );
}
if (maxAge != null) {
crit.add( le("age", maxAge) );
}
members = crit.list();
}
Do I make a mistake in how to use DetachedCriteria in Seam app?
Thanks in advance.
