Update + composite-id

Hi,

I will like to know how to update value of a composite ID.

Here is an exemple of my code:

<composite-id name="etudiantSommairePeriodePK" class="EtudiantSommairePeriodePK"
unsaved-value="any">
<key-property
name="typeDossier"
column="TYPE_DOSSIER"
type="java.lang.String"
length="2"
/>
<key-property
name="dateDebutExemption"
column="DATE_DEBUT_EXEMPTION"
type="java.util.Date"
/>
<key-property
name="noSeqEtudiant"
type="java.lang.Integer"
column="NO_SEQ_ETUDIANT"
length="9"
/>
</composite-id>

I create a class for my composite ID EtudiantSommairePK but each time i try to modify one of this three values I have the following error:

13:57:04,659 ERROR DbHibernate:200 - net.sf.hibernate.UnresolvableObjectException: No row with the given identifier exists: com.macrocontact.app.model.db.persistence.EtudiantSommairePeriodePK@244e2739, of class: com.macrocontact.app.model.db.persistence.EtudiantSommairePeriode

can someone help me

Thx

Lud

Just a side comment, not what you are looking for, but from a database perspective in general one should not modify the primary key of an existing record.

It is true for Hibernate too
