Hi guys, since a downloaded the latest DO version I have problems with the one Structure class I have.

Are there any changes that could have caused this? Example:

public class MyEntity: Entity
{
   [Field]
   public MyStructure MyStructureProperty {get; private set;}

   public MyEntity()
   {
      MyStructureProperty = new MyStructure("This is new"); 
      //Error occors right after the line above.
   }
}

public class MyStructure: Structure
{
   public MyStructure(string value)
   {
      Set(value);
      //So far so good, constructor does not fail...
   }
   [Field]
   [NotNullOrEmptyConstraint]
   public string Value { get; private set; }

   public void Set(string value)
   {
      Value = HashHelper.ApplySoopahDoopahHash(value ?? string.Empty);
   }
}

And the error is like this:

 System.ArgumentNullException: Value cannot be null.
