not able to get a proper hashmap for a DWR call

Question

I am trying to pass a string of data which is a hashmap from a javascript to a java function by making an Ajax DWR call as below:

var str11 = {
             "78965":{"age":"34yrs","height":"4"},
             "44589":{"age": "32yrs", "height": "99yrs"}
            };

person= 233453;

Person.saveSelected(planOid,
                    str11,
                    {
                     callback:savedValues,
                     errorHandler:handleError
                    }
                   );

But at the other end in my Java class i.e PersonService.java, I receive both of the params successfully but when I examine the hashmap it takes the form as below:

{
 44589={age:reference:c0-e5, height:reference:c0-e6}, 
 78965={age:reference:c0-e2, height:reference:c0-e3}
}

I am not able to understand why the the references. Instead I am expecting a proper hashMap . Can any one sort out what the problem is with DWR marshaling behind the scenes?

Could you post the Java code for your Java object that you are placing in the hashmap (the one with age and height)? — Doug Porter, Feb 17 '11 at 20:18

Map<String, Object> is not specific enough for DWR to know which object to instantiate. So you will have to use Map<String, YourConcreteClass> (a collection in you case).

This means that you cannot use different types for values in your map (which shouldn't be problem in your case).
