[hibernate-dev] [OGM] MongoDB JPQL Query: comparison with object fails

Hello, I found an problem with the MongoDBComparisonPredicate. When I try to make a jpql query with an object comparison [1] The value (here a SolutionType instance) is "directly" passed to the MongoDBComparisonPredicate which tries to use it as it is, in a DBObject query. The point is, the refering property is solutionType_id (which is correct) but instead of using the parameter id, it's using the complete object [2] The MongoDB drivers returns that it can't serialize the type passed in parameter.. There is something I don't get, why for basic CRUD operations do we use dehydrated object and for queries as well ? Object parameter (all paramater that are not String, or wrappers) would be easier to use. WDYT ?
