UpdateAndRemovedFlags removeRelation(TransactionContext tx, java.lang.Object object, ClassMolder relatedMolder, java.lang.Object relatedObject)
If the related object is PersistanceCapable, the field will be set null. If the related object is a Collection, then the related object will be removed from the Collection.
If any changed occured, transactionContext.markModified will be called, to indicate the object is modified.
It method will iterate thur all of the object's field and try to remove all the occurrence.
