Thanks in advance for any help.

I have a user Entity that is stored in a WebApp Session object upon login. This object is created via a request to a Query object obtained through a Manager which is immediately closed.

I want to associate this user Entity to other types of Entities when they are created via a differenct Manager. When I create these other type of Entities (which have a many-to-one relationship with the user Entity) I get an exception:Detached entity passed to persist.

I try to re-attach the Entity by executing Manager.merge(user); but I still get the error.


Thanks in advance for any tips/advice.

Well - I figured out what I was doing wrong.

In addtion to using manager.merge(user) I also had t use manager.merge(otherEntity) instead of manager.persist(otherEntitiy).

In otherwords, I misunderstood that I only had to merge the detached object and then I could persist the newly created object which reference the (now attached) object. Instead, I merged both.

Its working now, but any additional opinions/feedback welcomed.
