Hi!

I'm having difficulty in designing a good mapping for a particular class I've used in the past. The problem class is called Document which amongst other things has a hashmap of language codes to Body's.
My problem is replicating the keys in hibernate. A Body contains a particular translation of the Document and a Language and I want to use the body.language.code as the key.

I've tried the following two index settings...




In the first example I was happy for the key to be a Language object instead of a String but I ended up with serialized languages in my bodies table.
I didn't expect the second example to work but maybe shows what I'm after :-)

Is it possible to achieve the mapping I'm after or is there another way I could think about the problem?

Thanks.
