Should derived fields of an EmbeddedId be manually maintained by app code?

If I have an Entity which has a primary key which is derived and I am implementing it using @EmbeddedId, am I responsible for maintaining the derived fields of the @EmbeddedId?

I have a application that initializes with spring, now I'd like to change my data access tier to ObjectDB (from Hibernate : HSQL), but I couldn't find any useful information on it.

Mapped (Inverse) LAZY @OneToMany vs. Unmapped LAZY @OneToMany

In the code example below (also attached) I would like to understand why I am able to print to console a lazy @OneToMany mapped field after a finding entity manager closes. There is a switch DO_VIEW_BEFORE_CLOSE, and when it is true the fields are accessed and output before the finding entity manager closes and as expected both a mapped @OneToMany list and an unmapped @OneToMany list are viewable: a.listA_mapped:[{A}[4]"ownedElement1", {A}[5]"ownedElement2"] a.listB_unmapped:[{B}[2]"b1", {B}[3]"b2"] ... {B}[3]"b2"] When I set DO_VIEW_BEFORE_CLOSE false, so that the fields are only accessed after the finding entity manager ... gives an empty list [], when DO_VIEW_BEFORE_CLOSE = false. --- Webel IT Australia, "The Elements of the Web", ...
