Hello,

Look at the following code, where Foo has a one to many lazy relationship whith boo.

1 - Foo foo = em.find(fooid);
2 - foo.setBoos(null);
3 - em.update(foo);

When em.update is executed (line 3), before the execution of UPDATE sql command, a SELECT on table BOO is performed.

It does not happen if I don't set null to boo relationship(line 2).

For some reason I need to set null before the update but I wouldn't like that boo relationship would be fetched(it's lazy).
Is there a eclipselink configuration to avoid this behaviour.

Regards. Mauro.
