EntityMetamodel instantiation fails on Blaze-persist Alpha4

[jwgmeligmeyling]

EntityMetamodel instantiation fails on Blaze-persist Alpha4. In this case it fails on finding the id property of a referenced type for which the id property is defined in the super class.

(PartnerDiscountCode references GlobalPartner which extends Partner which has the id property).

The stack trace is as follows:

org.hibernate.QueryException: could not resolve property: partner.id of: com.pallasathenagroup.entities.PartnerDiscountCode

Thanks, gonna take a look at that later today.

Could you maybe explain the mapping to me? I used the following and the model build succeeded.

    @Entity
    public static class PartnerDiscountCode {
        @Id
        @GeneratedValue
        private Long id;
        @JoinColumn(name = "partner_id")
        @ManyToOne(fetch = FetchType.LAZY)
        private GlobalPartner partner;

    }

    @Entity
    public static abstract class Partner {
        @Id
        private Long id;
    }

    @Entity
    public static class GlobalPartner extends Partner {
    }

These are the entities: https://gist.github.com/JWGmeligMeyling/b1e700b765600a67c77349fba9b12047

Perhaps the table per class inheritance strategy?

Thanks, have a reproducer now. Investigating the reasons now.

Thanks! 👍 Will verify the patch on my test suite
