Refresh Problem with manyToOne OneToMany relations in EJB3/0

Question

Hi all,
I have three tables defined.
Table A, B and C. B is an association table between A and C.
I have made a simple web application in which I can insert entries in the association table B.
The problem is now that when I insert a new entry in B the changes are not reflected to the defined @OneToMany relations in A and C, untill I restart the OC4J DP4 10.1.3.0 server.
I think the problem lies in the fact that the EJB relations are not refreshed properly.
Does anyone regconize this problem?
Thanks in advance

Sorry, no solution.
Would just like to add my weight to this post as Im having the same trouble unless of course you managed to resolve it in which case Id be grateful for your wsidom.
Two entites (created with CMP from tables wizard) Location contains Stock. Cascade of PERSIST defined.
Facade method to add stock to a location works (Correct values are insserted into the database) but subsequent finds return Stock entities that are unpopulated (i.e. all proeprties are null).
Im using latest JDeveloper 10.1.3 build 3673 downloaded a couple of days ago. Am running within JDeveloper also.
Facade method :-
public void writeOnStock(String loc, String prod, int qty, String container)
throws InvalidProductCode, InvalidLocationCode {
Location l = (Location) em.find("Location",loc);
if (l==null) throw new InvalidLocationCode(loc);
Product p = (Product) em.find("Product",prod);
if (p==null) throw new InvalidProductCode(prod);
Stock s = new Stock();
s.setProduct(p);
s.setQty(new Long(qty));
s.setContainer(container);
s.setStatus("-");
l.addStock(s);
My tester code...
stockFacade.writeOnStock("BAY1","LP1",1,"PAL1");
System.out.println( stockFacade.findAllStock( ) );
Output of...
[Stock:[null]null on null]
but stock table contains a row with all the correct data (Id of 45)
Stop and start the embedded OC4J server and run again I get...
[Stock:[45]1 on PAL1, Stock:[null]null on null]
As you can see record 45 from previous run is fine now, but latest is all null.
Any help appreciated. Gonna raise a TAR and upload my code. Ill post back if I get a solution.
