I've got a Domain Class which has a collection of component classes off it.
I'm having problems because the dirty checking algoritm seems to constantly think it is dirty, and so I get far too many updates of the owning Domain class, followed by Deletes/Inserts of the component classes in the collection.

I have implemented equals(...) and hashCode() for the component classes correctly.

Is there something specific about component classes and dirty checking that I should be aware of?

Hibernate version:
2.1.4
