Hi,

I don't know if it's a bug or optimization feature.

Lets say that I've got a Post entity and User entity.

In one query I do something like this:

->select('partial p.{id,slug,title}, partial pu.{id,username}') ->from('Post', 'p') ->leftJoin('p.user', 'pu')

and I've got another query in the same action and I do something like this

->select('partial u.{id,username,slug}') ->from('User', 'u')

The problem is that in result list of second query I'm getting a 1 user without slug. This object looks like it was taken from Post query.

I guess that it's caused by some internal doctrine optimization. But I don't know if it's a feature or a bug.

Without using partial queries you will not notice any problem.

Best regards,
Michal
