Spring Boot error with PUT operation and Entity View

[pvncoder]

Description

See Zulip discussion here

When performing a PUT operation on an Entity View object that contains an empty list in a Spring Boot + Blaze Persistence project, and using evm.saveFull(em, object) to save it, the following error occurs:

WARN 5624 --- [nio-8080-exec-2] .m.m.a.ExceptionHandlerExceptionResolver : Resolved [org.springframework.orm.jpa.JpaSystemException: A collection with cascade="all-delete-orphan" was no longer referenced by the owning entity instance: br.com.dto.MyEntityView.myEntityViewList]

Expected behavior

The saveFull operation should work for any Entity View that contains a list within it (even if it is empty).

Actual behavior

The saveFull operation fails with the mentioned error when attempting to save an Entity View object that contains an empty list.

Steps to reproduce

1. Download the zip file containing the test case (BlazePersistenceTestCaseSpringBootPutOperationIssue.zip);
2. Run the command ./mvnw clean install at the root of the project;
3. Run the Spring Boot project with your IDE of choice or using the command java -jar target/blaze-persistence-test-case-spring-boot-put-operation-issue-0.0.1-SNAPSHOT.jar;
4. Make a POST request to http://localhost:8080/users with the following JSON:

{
    "username": "007 AGENT"
}

5. After successfully creating a user, make a PUT request to http://localhost:8080/users/{idUser} with the following JSON:

{
    "username": "008 AGENT"
}

In this last PUT request, you should encounter the error I described earlier.
