Re: Eager fetching not working with enums and lobs

The spec doesn't seem to discuss it, but I think that lazy is a pretty

are big, so you often don't want them in the default fetch graph.

Enum is different, though. Enum should be eager fetching by default.

Lazy fetching is optional, so we can decide what we want to do. It seems that the existence of @Basic should not change our strategy. And we should default to lazy fetching for Lob and eager fetching for Enum.

I am finding that the supposed default action of Eager fetching is not happening with @Enumerated and @Lob fields. If I explicitly specify the @Basic annotation, then the fields are eagerly fetched. But, without this extraneous @Basic, these fields are lazily loaded. This action does not seem to be consistent with the spec. Nor, can I find any mention of this alternate behavior in our OpenJPA manual. Sounds like a bug to me. Any

other insights?

This works (eager loading kicks in):

    @Basic @Enumerated(EnumType.STRING)
    private Gender gender;

This does not work (lazy loading kicks in):

    @Enumerated(EnumType.STRING)
    private Gender gender;

I have also tried to use defaults (without any annotations), and lazy
loading still kicks in:

    private Gender gender;

Thanks,
Kevin
