what is wrong with my ExecuteQueryAsync?


   

 
public void FetchMembers(MemberQO q)
{
....
 
var query = PredicateBuilder.FilterQuery(entityManager.Members, aCompositePredicateDescription);

int token = 1;

entityManager.ExecuteQueryAsync((IEntityQuery)query, MembersQueryCompletedCallback, token);

}
