GridView with MongoDb AR model -- Filtering by _id doesn't work

I’m using GridView with Mongo ActiveRecord model.

I want to filter it by _id and it doesn’t work, always returns “No results found.”

Filtering by other attributes of the model works fine.

Any ideas why it doesn’t work and how to fix it?



            '_id' => new \MongoId($this->_id),


Thank you!
