Description

Given a POGO base class that expresses constraints (e.g. it is the parent of both a domain and @Validateable class):

src/groovy/bug/Parent.groovy

package bug

class Parent {
    String lastName

    static constraints = {
        lastName(nullable: false)
    }
}

And a domain class that extends from it:

domain/bug/Child.groovy

package bug

class Child extends Parent {
    String firstName

    static constraints = {
        firstName(nullable: false)
    }
}

A unit test that uses the new '@TestFor(Child)' style fails with the following exception:

Mapped identifier [id] for class [bug.Parent] is not a valid property
org.grails.datastore.mapping.model.IllegalMappingException: Mapped identifier [id] for class [bug.Parent] is not a valid property

The old-style unit test passes.
