Does ObjectDB support lazy loading?

I'm evaluating ObjectDB 2.0 RC1. Everything works fine except a lazy loading problem. I've a Parent class which contains List<Child>, marked with @OneToMany. After persisting a Parent object, (in the Explorer) I can see all the property values of the Child objects in the list. However, when the Parent object is read from EntityManager, all the properties except ID of the Child objects are null.

remove() and persist() in same transaction => Attempt to reuse an existing primary key value

Hello Support, in our configuration (FlushModeType.AUTO) is the execution of  em.find(Entity.class, <id>) much faster than an equivalent query. To optimize the Performance we define a special Entity (A) with additional data that use an existing ID of another Entity (B) from another class (another table). On this point we get no conflicts. If we remove additional data for Entity (B) and then the special Entity (A) is empty, we remove the special Entity (A). #1 2017-02-22 06:53 Hello Support, in our configuration (FlushModeType.AUTO) is the execution of  em.find(Entity.class, ...
