Entity object not getting persisted: new object was found through a relationship that was not marked

[Kshitiz Agarwal]

Hi,

I am trying to persist the following entity:

public class CommentEntity {
	
	@Id
	
	@ManyToOne(optional=false,cascade=CascadeType.REFRESH, targetEntity=UserEntity.class)
	@JoinColumn(name="USERID",referencedColumnName="USERID")
	private UserEntity userEntity;
	
	@ManyToOne(optional=false,cascade=CascadeType.REFRESH, targetEntity=PostEntity.class)
	@JoinColumn(name="POSTID",referencedColumnName="POSTID")
	private PostEntity postEntity;
	
}

But the error comes out:

During synchronization a new object was found through a relationship that was not marked cascade PERSIST: entity.PostEntity@16afec.
but when I try to persist PostEntity, it is persisted. No such exception is thrown:

public class PostEntity {

	@ManyToOne(optional = false, cascade = CascadeType.REFRESH, fetch = FetchType.LAZY, targetEntity = UserEntity.class)
	@JoinColumn(name = "USERID", referencedColumnName = "USERID")
	private UserEntity userEntity;

	@OneToMany(cascade = CascadeType.ALL, mappedBy = "postEntity", fetch = FetchType.LAZY)
	private List<CommentEntity> commentEntityList;
}

Why it is happening? UserEntity is:

public class UserEntity {

@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "userEntity")
	private List<PostEntity> postEntityList;

	@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "userEntity")
	private List<CommentEntity> commentEntityList;
}

I am using EclipseLink
