I'm currently migrating my grails code from version 2.5.6 to 3.3.9. On 3.3.9, I observed this weird behaviour:
There's an abstract class (in src/main/groovy) which contains a hasMany relationship.
package srcFolder
import grailsthree.TestSimpleClass
abstract class TestSuperClass
String superClassValue
static hasMany = [simples: TestSimpleClass]
A domain class which inherits this abstract class.
package grailsthree
import srcFolder.TestSuperClass
class TestSubClass extends TestSuperClass
String subClassValue
static constraints =
In the Bootstrap, call the addTo on the hasMany property of subclass,
package grailsthree
class BootStrap
def init = servletContext ->
TestSimpleClass testSimpleClass = new TestSimpleClass(simpleClassValue: 'simpleClassValue').save()
TestSubClass testSubClass = new TestSubClass(subClassValue: 'subClassValue')
testSubClass.addToSimples(testSimpleClass)
testSubClass.save()
def destroy =
Got following error:

annotate you superclass with@grails.gorm.annotation.Entity

Mar 22 at 8:55
@injecteer I tried that as well, but it creates a table in the DB corresponding to my abstract super class. My main motive is to use this abstract class to inherit the properties in the sub-domain classes.

Mar 22 at 9:34
creation of a table for the parent class and use of discriminator field --> this is how inheritance works in GORM. You can specify the explicittableNameinmapping...though, but the discriminator_clazzfield will still be created in the table
– injecteer
Mar 22 at 10:26
@injecteer, yeah I get that. It's just that I don't want it to be treated as a domain class. As I mentioned, my intention to use this abstract class is for inheriting the properties in the sub-domain classes.

@injecteer, yeah I get that. It's just that I don't want it to be treated as a domain class. As I mentioned, my intention to use this abstract class is for inheriting the properties in the sub-domain classes.

@injecteer I tried that as well, but it creates a table in the DB corresponding to my abstract super class. My main motive is to use this abstract class to inherit the properties in the sub-domain classes.
