Hi there, in my test i found out, that the postpart is not stored in the database. I fix that by annotate the PostPart Reference with @OneToOne(optional = false, cascade = { CascadeType.ALL }) @JoinColumn(name = "POST_PART_ID", unique = true, nullable = false, updatable = false) otherwise the id of PostPart will be null and it would not be stored in the database. Are you agree with that??? regards
