i am getting an exception when trying to create a bean(patient) and then update a cmr field(location) in the ejbpostcreate method of patient bean(shown in the example below)
location---------> patient
1 to many (unidirectional)
i am having only local,localHome interfaces for both the beans and location is represented only as cmr field in the patient bean
