Mapped-superclass persisting only few columns of Parent class

Hello,

I don’t have access to source of Parent class. So I have chosen XML configuration.
Parent class name: LineItem (from admanager package)
Child class name: LineItemCustom

I want to persist parent class attributes inside child class’ table. So I went with “mapped-superclass”.
Astonishingly, only two fields from the Parent class is persisting. In my case, “creativeTargetings” and “targeting” are Persisting from LineItem class (Parent).

I tried the same mapping with “Event” and “ExtendedEvent” classes for testing purpose. It’s working fine. I’m even getting of “id” field of parent. But only in case of “LineItemCustom”, all fields are not persisting.

Can anyone point out what’s wrong here.

Thank you.

You need to add all classes to the post and remove the link to Google Drive. Afterward, I’ll investigate it and help you with your mapping.

Hello vlad,

I’ve updated by question with classes.

Thank you.

You need to add mapped-superclass for LineItemSummary if you want to persist properties from that base class.

Now, the best way to see how that can be done is to provide a replicating test case using this template. Once you have the test case running, give e the URL to your GitHub repository so I can investigate it.

And, use a simpler class hierarchy because the one you provided has too many properties that are not relevant to this problem.
