Creating OrderBy annotation for OneToMany [message #1748966]

Hello,

I use EMF to model my entities and texo the create JPA annotated classes. What I cannot model directly, I do with the annotation model. Up to now I could model everything I needed. Except the following:

@OneToMany(cascade = { CascadeType.ALL }, mappedBy = "parameters", orphanRemoval = true)
@OrderBy("id")
private Set<Parameter> parameters;

What I want: I'd like to query the list of parameters in the order they where inserted in the database. I don't want an extra table nor an OrderColumn. With plain JPA it works but I cannot make texo to add the @OrderBy annotation.

Is this possible? How?

Kind regards,
Michael Wyraz.

Hi Michael,
Yes it should be possible. What does get generated in the source code?

Another option/thing you can try is put the orderBy as a property of the OneToMany.

But when I check the source code it should work either way.

If you post the relevant part of the annotations model here then I can take a look and create a testcase for it also.
