Jan Schumacher ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=60d46a1... ) *commented* on HHH-15874 ( https://hibernate.atlassian.net/browse/HHH-15874?atlOrigin=eyJpIjoiN2IwND... ) Re: Can't access override property in sub-class when use kotlin data class ( https://hibernate.atlassian.net/browse/HHH-15874?atlOrigin=eyJpIjoiN2IwND... ) I think the problem lies in the problem lies hier: https://github.com/hibernate/hibernate-orm/blob/6.1/hibernate-core/src/ma... ( https://github.com/hibernate/hibernate-orm/blob/6.1/hibernate-core/src/ma... ) When Entity2 gets loaded the fields of Entity1 are already loaded and are not considered to be part of Entity2. In https://github.com/hibernate/hibernate-orm/blob/6.1/hibernate-core/src/ma... ( https://github.com/hibernate/hibernate-orm/blob/6.1/hibernate-core/src/ma... ) are the mappings of Entity1 returned and only the setters of Entity1 are called. That ignores the child class (Entity2) totally. I wonder what the differences are between Overriding Properties and just declaring them ( https://hibernate.atlassian.net/browse/HHH-15874#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-15874#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
