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(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.
