Query with Enum Object.

[GoogleCodeExporter]

morphia-0.98 ,driver-2.3,mongo,1.6.4 ,os- ubuntu

I got a entity like this:

   class Book {
      private Type bookType;

      public static enum Type {   // it's necessary to declare the enum to static?
         Paper , Ebook
      }
   }

   After I saved a entity into mongo , I got a record: {book:{ bookType:"Ebook" }}.
   When I query : createQuery().disableValidation().filter("bookType", SpaceType.Ebook) ,
   there won't have any result return,util I query this it using "name()",
   createQuery().disableValidation().filter("bookType", SpaceType.Ebook.name()) ,

   I track down the code ,and found : 
        .morphia.query.FieldCriteria# protected FieldCriteria(QueryImpl<?> query, String field, FilterOperator op, Object value, boolean validateNames, boolean validateTypes) [line 67]
              else
           mappedValue = mapr.toMongoObject(value);

         and value is SpaceType.Ebook -> which turned into { "name" : "support" , "ordinal" : 2} ,
   I don't know whether this will affect the query result.

   So , I have using createQuery().disableValidation().filter("bookType", SpaceType.Ebook.name()) ,which looks a little....

I added a simple Test for this in the trunk called "EnumMappingTest". I am not 
able to reproduce the problem. 

gogomatrix: can you please take a look if the problem perists and maybe tweak 
the test to demonstrate the problem?

patched the mapper to use the parent class instead of the given one for 
instances of an anonymous class where the parent class is an enum.

shouldn´t this behaviour generally be true? (not just for enums)
