I am writing a web application and am trying to let users updated the employee and team objects. The gist of the situation is that the team object contains a Set of employee Objects and a reference to another Employee Object ( the team leader).
I am trying to have the user submit the team object id and the id of the employee who is to be the team leader.
I can load the team without any errors, but when I try to load the employee hibernate is telling me that the object with that id has already been loaded by the session. I know the problem is that the Employee I am trying to setup as the teamLeader is already a member of the Team and is therefore being loaded by hibernate, but I am not certain how to overcome this problems.
Does anyone have any suggestions as to how I can get a reference to both objects, the team and the employee, at the same time without generating this error?
