Hi all.
First of all I have to admit: I havent read all the docs.
I had a small app running, it basically has this:
A User:
@PersistenceCapable(detachable = "true")
@FetchGroup(name = "_post", members = { @Persistent(name = "posts") })
public class User implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent(mappedBy = "user", defaultFetchGroup = "true")
@Element(dependent = "true")
private List<Post> posts;
....
}
A thread :
@PersistenceCapable(detachable = "true")
@FetchGroup(name = "_user", members = { @Persistent(name = "user")})
public class Thread implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long key;
@Persistent(defaultFetchGroup = "true")
@Element(dependent = "true")
private User user;
...
}
So now I want to add comments, each comment will have: the user that made
the comment, and the thread that it belongs to, and some other fields:
@PersistenceCapable(detachable = "true")
public class ThreadComment implements Serializable{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key key;
@Persistent(defaultFetchGroup = "true")
@Element(dependent = "true")
private User user;
@Persistent(defaultFetchGroup = "true")
@Element(dependent = "true")
private Thread thread;
...
}
I changed the Thread to include a list of comments:
@PersistenceCapable(detachable = "true")
@FetchGroup(name = "_user", members = { @Persistent(name =
"comments"),@Persistent(name
= "user")})
public class Thread implements Serializable {
....
@Persistent(defaultFetchGroup = "true")
@Element(dependent = "true")
private List<ThreadComment> comments;
}
My problem is that meanwhile this works in memory when I try to persist the
ThreadComment
PersistenceManager pm = getPMF();
Transaction tx = pm.currentTransaction();
tx.begin();
thread.addComment(comment);
pm.makePersistent(comment);
tx.commit();
pm.close();
the code gets excecuted but I don't see the comment in the database (in fact
the logs show no db activity either)
So I don't see an exception, the code gets excecuted but I don't see the
comment in the DB.
I already have the db with soem threads without comments, this is a "new
feature"
Any idea of what I'm doing wrong? (please don't say everything :D )
Thanks!
Fernando
