how to refresh a collection after new object is added?

Hi, Everyone,

I have two entity classes: Centre and User. (One Centre has many Users).

Once I add a new User into the user list of a Centre, it is not in the list retrieved by 'centre.getUserCollection()'.

I guess the object 'centre' is not properly refreshed/updated after the new user has been inserted.

If I use the EntityManager to refresh the centre, the newly added user appears in the list.

Is this the normal way to keep the centre object fresh?

The puzzle has been solved. I should always ask the Facade for latest/fresh objects after changes.
