Description Heiko W. Rupp 2008-11-03 06:39:00 EST
The current implementation has a public no-arg constructor for PropertySimple().
This allows for the following 

PropertySimple ps = new PropertySimple();

yielding in a NPE later on when doing the writeExternal(), as there has never been a name set for this property.

We should require the name here, especially as the superclass marks the name as required:

    @Column(name = "NAME", nullable = false)
    private String name;
Comment 1 Joseph Marques 2008-11-04 16:32:48 EST
a protected no-arg ctor is needed according to the JPA spec.  Seam requires the no-arg ctor to be public if you want to use it for bijection.  so, this method needs to stay.  please close this case if you agree, or post back if i'm missing the point.
Comment 2 Heiko W. Rupp 2008-11-18 06:55:51 EST
I understand the Seam requirement, which is sad to be there.

Again, a PropertySimple without a name is incomplete. So we should prevent its usage when no name is present.

As just requiring the name via a constructor with arguments (and hiding the empty one) is not possible, one can perhaps print an error in writeExternal() and some @PrePersist hooks.

I've at least added a comment about this in rev2022
