NHibernate - QBE and EnableLike ()

I have a problem using QBE with NHibernate.

Here's some sample code:

Person person = new Person();
person.FirstName = "e";
using (ISession session = SessionFactory.CreateSession())
{
  Example example =    Example.Create(person).ExcludeProperty("DateOfBirth").EnableLike().IgnoreCase();
  IList<Person> people = session.CreateCriteria<Person>().Add(example).List<Person>();
  return people;
}

      

        
        
        
      

    

I expect this example and criteria to return all individuals whose name begins with the letter "e". BUT, for this I had to insert an escape character in the example property of the object. Like this:

person.FirstName = "e%";

      

        
        
        
      

    

With this modification, the query returns the desired results. Should "EnableLike" take care of this?

What am I doing wrong?

Thank!
