Crash on loading serialized object from intent in To-Many case

See original GitHub issue

hi, the issue is, I have a Receipt class with an arraylist of items. so I used ToMany relation and changed arraylist to To-Many and in ReceiptItem class created a new field with To-One relationship. Its working fine and saving in 2 tables properly.

@Entity
public class Receipt implements Serializable {
    public ToMany<ReceiptItem> receipt_items;
   .... 
}
@Entity
public class ReceiptItem implements Serializable {
    public ToOne<Receipt> receiptToOne;
}

I am sending my receipt object from one activity to another activity by serialization and getting in another activity. receipt = (Receipt) (intent.getSerializableExtra(“key_receiptobject”));

No issues and this is working fine.

Now for proper One-To-Many relationship I added, @Backlink annotation.

@Entity
public class Receipt implements Serializable {
    @Backlink
    public ToMany<ReceiptItem> receipt_items;
   .... 
}

and my app crashes on this line, receipt = (Receipt) (intent.getSerializableExtra(“key_receiptobject”));

Can you please help me to resolve this.

@jesualex Don’t do it. Android does not support this right now. Instead just pass the ID and get the object in the new activity/fragment/… -ut
