Detached entities 'ToMany.addAll' throws error

Issue Basics

• ObjectBox version 1.4.4
• Reproducibility: Always

Reproducing the bug

When creating entities (for inserting into ObjectBox), the ToMany field will throw this error if I use .addAll(list) it works if I use .add(entity) in a loop over the list.

Code

entity.bodyparts.addAll(bodyparts)

Logs & stackstraces

io.objectbox.exception.DbDetachedException: Cannot resolve relation for detached entities at io.objectbox.relation.ToMany.ensureBoxes(ToMany.java:144) at io.objectbox.relation.ToMany.ensureEntities(ToMany.java:184) at io.objectbox.relation.ToMany.ensureEntitiesWithTrackingLists(ToMany.java:155) at io.objectbox.relation.ToMany.trackAdd(ToMany.java:230) at io.objectbox.relation.ToMany.addAll(ToMany.java:264)

Entities

lateinit var bodyparts: ToMany<BodypartEntity>

Misc

As mentioned above, the issue seems to be with .addAll specifically, whereas .add does work. The issue happens with detached entities, not using @Id(assignable = true).

从 ToMany.java 中的 io.objectbox.relation.ToMany.addAll 开始，然后将其经过 ensureBoxes、ensureEntities、ensureEntitiesWithTrackingLists 和 trackAdd 的路径，与报告中描述的可正常工作的 add 循环进行比较。当 detached entities 可以传递给 addAll 且不会抛出 DbDetachedException，并且已覆盖报告中的复现案例时，即视为完成。
