Hi,
I have a entity and a emdeddable class as below.
================================================
@Entity(name = "ARTICLE")
public class Article implements Cloneable,Serializable{
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private long id;
@Embedded
private Content content;
@Version
@Column(name = "VER")
private long version;
}
@Embeddable
public class Content {
@Lob
private String content;
public String getContent() {
return content;
}
public void setContent(String content) {
this.content = content;
}
}
======================================================
When I run the below code with enhancer, everything works fine,
==========================================================
tx.begin();
Article article = em.find(Article.class,11);
article.getContent().setContent("Once upon a time there is a city of
Hamelin!!!");
tx.commit();
=================================================================
But without enhancer, it gives me the below error.

When I traced back, I found the below code in BrokerImpl(kernel package)
where the embadable stateManager is getting added to the _untracked.
public void add(StateManagerImpl sm) {
if (!sm.isIntercepting()){
if (_untracked == null)
_untracked = new HashSet();
_untracked.add(sm);
}
....................
}
If I change the above code to , everything works fine..
public void add(StateManagerImpl sm) {
if (!sm.isIntercepting() && !sm.isEmbedded()) {
if (_untracked == null)
_untracked = new HashSet();
_untracked.add(sm);
}
....................
}
Not sure whether it is a feature of enhancer or a bug..Or am I missing
out any annotation/property etc.?
Please let me know,
Aditi
