See forum topic.

Steps:

1. Download and run project: unfetch.zip
2. Open Blank Screen
3. Press upper button, then bottom button
   ER: No exceptions
   AR:

java.lang.IllegalStateException: Cannot get unfetched attribute [infoEntity] from detached object com.company.jmix_unfetch.entity.LastEntity-92a4bf42-6755-3b2a-c5ba-2badd96853f2 [detached].
	at org.eclipse.persistence.internal.indirection.UnitOfWorkValueHolder.throwUnfetchedAttributeException(UnitOfWorkValueHolder.java:326)
	at org.eclipse.persistence.internal.indirection.DatabaseValueHolder.getValue(DatabaseValueHolder.java:106)
	at com.company.jmix_unfetch.entity.LastEntity._persistence_get_infoEntity(LastEntity.java)

	at io.jmix.core.common.event.EventHub.publish(EventHub.java:170)

Cause:

UnitOfWorkQueryValueHolder is not wrapped for infoEntity property in deeply nested entity LastEntity, because it is already loaded despite absence in fetch plan.

see io.jmix.eclipselink.impl.lazyloading.JpaLazyLoadingListener#processValueHolders

Possible solutions:

a. Prevent excessive loading
b. Modify wrapping logic
c. leave as is if there are no "good" solutions
