[eclipselink-users] How to use unitOfWork.getUnitOfWorkChangeSet()

["Mathias Walter" <mathias.walter@xxxxxxx>]

Hi,

according to the docs:

public UnitOfWorkChangeSet getUnitOfWorkChangeSet()
ADVANCED: Returns the currentChangeSet from the UnitOfWork. This is only
valid after the UnitOfWOrk has commited successfully.

I do not use UnitOfWork explicitely. I do tx = em.getTransaction(),
em.merge(entity) and then tx.commit(). em.getUnitOfWork() returns the
UnitOfWork in this way. But why is the UnitOfWorkChangeSet null?

How is the correct way to use getUnitOfWorkChangeSet or are the docs wrong?
