Populate: can't deselect '_id'

[klimashkin]

Hello!
When I'm trying to deselect '_id' field in populate (when it is array of refs), then I always get empty array.

new mongoose.Schema(
        {
            geo: {type: [Number], index: '2d'}, 
            photos: [
                { type: Schema.Types.ObjectId, ref: 'Photo' }
            ]
        },
        {
            strict: true
        }
    )

SomeCollection.find({geo: { "$within": {"$box": box} }}).populate('photos', {_id: 0}).select('-_id photos').exec(function (err, docs) {
console.dir(docs); // get here: [ { photos: [] }, { photos: [] }, { photos: [] } ]
});

If I don't deselect '_id', than all is ok: photos array for each doc is not empty

Thanks for the detailed report. I'm looking into it now.
