  As my problem was only with hierarchy childs (and only in the database =
layer), I've changed one line in HibernateEntity.vsl (into hibernate =
cartridge)

  line 75 changed from:
  #if($attribute.required)
       *     not-null=3D"true"
  #end

  to
  #if($attribute.required && !$entity.generalization)
       *     not-null=3D"true"
  #end

  It runs fine for me. :-)=20

    Hi all,

    I'm getting an unexpected non-null error from the database.
    I have M3 version, from a week or two ago.

    I have a hierarchy of clases C, C1 and C2. C1 and C2 are sons of C, =
they're at the same level.
    I have an attribute att1 in C1 and another one att2 in C2.

    When I try to make a save of C1 I get: Missing non-NULL value: att2.

    In fact, in my C1 object I have no attribute att2 to set...

    I know that is because of the one table per hierarchy solution.
    I've thinked two ways of solving it:
        - setting the attributes of every child of the hierarchy as =
nullables. (this makes the scenario unreal, because the attributes are =
not nullable for the subclasses)
        - setting the attribute a default value in the model. (I haven't =
see any change, neither in the java class, neither in the create table =
sentence)

    Is there any other way to solve it?

    Thanks
    Bruno
