I have this two documents:

{
foo : "test2",
rel : [

{ $ref : "bar", $id : ObjectId("54773af88328753e92484be8") }
,
{ $ref : "bar", $id : ObjectId("54480b5f18c7885d7651a140") }
]
}

{
foo : "test2",
rel : [

{ $ref : "bar", $id : ObjectId("54480b5f18c7885d7651a140") }
,
{ $ref : "bar", $id : ObjectId("54773af88328753e92484be8") }
]
}

When I use $pull to remove some of DBRef entries and using $in too, none of them are removed.

This is the query:

db.test.update({}, {$pull:
{ rel:
{ "$id":
{ $in: [ ObjectId("54773af88328753e92484be8"), ObjectId("5477954518c7885d7651a15a") ] }
}
}
})

When I use $pull to remove some DBRef using $id and $in operator, none of them are remove.

If the $id field have another name works.
