Hi,
I am trying to clone a record using CopyGroup with the following parameters and code.

CopyGroup copyGroup = new CopyGroup();
copyGroup.setShouldResetPrimaryKey(true);
ServiceClass serviceNew = (ServiceClass ) em.unwrap(JpaEntityManager.class).copy(service , copyGroup);

my FetchType is FetchType.LAZY
I am using generator @GeneratedValue(strategy = GenerationType.SEQUENCE,generator = "TASKS") for generating new primaryKey while cloning

It is copying the record only for the Service table , I want to acheive new rows to be created in the child (Foreign key dependent) tables with their actual data corresponding to the given Service table PrimaryKey. How to acheive this ??
