Hibernate version:
3.0.5 + Annotations beta 2

Name and version of the database you are using:
MySQL 4.0

Is there any situation in which a Hibernate initialized List (@OneToMany) can contain null values?

I have moved the respective persistant class from @Proxy(lazy = false) to @Proxy(lazy = true), and I am occasionally (!) getting null values in a certain list. These null values are always replacing a refence that should be present, so they never seem to be there in addition.

Regards,

Andreas
