Re: [eclipselink-users] EclipseLinkM6 doesn't properly detect added/chan

[James Sutherland <jamesssss@xxxxxxxxx>]

My guess is that when you import the data you are not setting both sides of
the relationship.  Perhaps you are inserting details that set their master,
but never add the detail to the master.  In JPA you must always maintain
both sides of a bi-directional relationship.

See,
http://en.wikibooks.org/wiki/Java_Persistence/Relationships

EclipseLink maintains a shared cache by default, so after the import your
out of synch objects are in the shared cache.  The correct solution is to
fix your import, but you can refresh an object from the database through
refresh() and you should then see the details.  Also you could disabe the
shared cache through the "eclipselink.cache.shared.default"="false".
