Is there a good solution to CRUD a user's Profile2 fields via Services? I assume this can be done with Services Entity API, but I wonder if there is a more direct integration?

With [Services Entity API](https://drupal.org/project/services_entity), I enabled the `entity_profile2` endpoint and can load an index of profiles. I need to disable the ability to index the profiles but allow a user to retrieve their own profile.

From the docs, this URL should be able to find user with uid=296's profile:

`api/entity_profile2.json?parameters[uid]=296`

But the result is an empty page.
