[news.eclipse.rt.eclipselink] Cache Refresh Problem

[Rui Tang <tangrui.cn@xxxxxxxxx>]

Hello friends,

I have a bidirectiion one-2-many relationship between A and B.

A is the ONE side, and B is the MANY side.

Now I add an instance of B (say b) into database.

B b = new B();
b.setA(a); // suppose that I've already had an A instance.
session.persist(b); // surround this code I've opened a transaction

Outside this transaction, I open a new one then use
a.getBs(); // the same a in database
to fetch all related B, but I cannot get the set that contains the new added object b.

I also tested that, if I explicitly set a.getBs().add(b); then the result seems right.

But I'm wondering that, when I persist(b), all the relations have been saved in database, but it seems that the cache not refreshed, this case leads a.getBs() cannot get the new added b, because:

1. no database query performed
2. the cache has not been refreshed automatically or manually

So can anyone tell if this is a bug or the common behavior of EclipseLink? Because Hibernate may work OK without manually add b to a, because A is the master side.

Thank you for help!
