Assume we have a parent class and a child class each in a one to many releationship with the classes ParentAssoc and ChildAssoc as follows: class Parent { def hasMany = [parentAssoc:ParentAssoc] static mappedBy = [parentAssoc:"parent"] } class ParentAssoc { Parent parent String paProp def belongsTo = Parent } class Child extends Parent { def hasMany = [childAssoc:ChildAssoc] static mappedBy = [childAssoc:"child"] } class ChildAssoc { Child child String caProp def belongsTo = Child } After running create-all for all these domain classes, the resulting edit view for the domain class child has a link for adding a ParentAssoc but no link for adding a ChildAssoc. I have isolated this problem and put into a webtest. (Webtest plugin stripped from zipfile)
