[eclipselink-users] EclipseLink might be caching entity relations with i

[Enrico Maria Crisostomo <enrico.m.crisostomo@xxxxxxxxx>]

Hi.

I'm experiencing a strange behaviour when EclipseLink seem to
incorrectly fetch relations of an entity with itself.

I have an entity, Account, which is used to model a hierarchy of
accounts: every account may have a (nullable) parent and a collections
of children (mapped by the parents' relationship). Parents and
children properties of the Account entity are annotated with default
valued @ManyToOne and @OneToMany(mappedby="parents") annotations. When
an Account entity is updated in the db, setting
it's parent property, the parent Account children list is not updated
accordingly when such entity is fetched from the db. Upon restart of
the application, the first time Accounts are loaded they're correctly
populated. I also tried using a @JoinTable, which is created and
populated correctly, but the behaviour is the same.

In case you wonder, Account equals and hashCode only check Account's
autogenerated Long primary key.

I also have other parents-child relationships between different
entities and they are correctly fetched from the db. I suspect this
behavious is restricted to this case because of an entity being
maintaining such relationships with itself.

Have this behaviour been observed before, might I be missing something
or might this be a bug?

Thank you in advance for your help,
Enrico
