GRAILS-1623: Validation does not cascade properly for domain subclass

[graemerocher]

Original Reporter: jkranes Environment: Grails 0.6 Version: 0.6 Migrated From: http://jira.grails.org/browse/GRAILS-1623

Validation does not cascade properly to a related domain class if the containing class is a subclass.

Example:

class Book { String title Integer pages static belongsTo = [Author] static constraints = { pages(range: 0..100) } } class Author { String name Book book } class Novelist extends Author { }

Validation will correctly cascade from Author to Book for an instance of Author, but fails to do so for an instance of Novelist:

class ValidationTests extends GroovyTestCase {

  // Passes as expected

void testCascadeValidation() {
    def b = new Book(title:'The Definitive Guide to Grails', pages:9999) // pages violates range constraint
    def a = new Author(name:'Rocher', book:b)
    assert a.validate() == false 
}

   // Fails!

void testCascadeValidationWithSubclass() {
    def b = new Book(title:'War & Peace', pages:9999) // pages violates range constraint
    def a = new Novelist(name:'Tolstoy', book:b)
    assert a.validate() == false  // Fails -- validation passes!
}

}
