Hibernate version: 3.1

..beginTransaction();

MySmallObject localRef new MySmallObject(); // holds a collection
session.save(localRef);

MyOtherObject localRef2 = new MyOtherObject();
localRef2.setProperty(localRef)
session.save(localRef2);

// reusing the MySmallObject declaration above!!
localRef = new MySmallObject(); // holds another collection
session.save(localRef);

// reusing the OtherObject declaration above!!
localRef2 = new MyOtherObject();
localRef2.setProperty(localRef);
session.save(localRef2);

..commit();

The strange effect that happens:

All collectioins of localRef (for both instances) get saved correctly but: the first MyOtherObject that got saved to the db misteriousely has a reference to the last MySmallObject instead of the correct one.. (alway the last instance reference of localRef gets saved with the MyOtherObject references!!

This only happens if there are collections in the MySmallObject. Why is it not possible to reuse local declarations in such a szenario?

Comitting and reopening the transaction does not help.
