Body
I have a class like this: <pre><code>@Entity @Indexes(value={ @Index(name="idx_produto", columnNames={"codigoInterno"}), @Index(name="idx_produto_ean_com",columnNames={"eanComercial"}), @Index(name="idx_prod_unicidade",columnNames={"codigoInterno","empresa_id"}) }) @Customizer(ProdutoCustomizer.class) @AggressiveCache public class Produto implements Serializable { private static final long serialVersionUID = -4801725521366642420L; @Id @GeneratedValue(strategy=GenerationType.IDENTITY) private Long id; @Column(nullable=false, length=14) @NotEmpty(message="É obrigatório um código interno") @Length(max=14, message="O código interno não pode ultrapassar 14 digitos") private String codigoInterno; @Embedded private Combustivel combustivel = new Combustivel(); </code></pre> when I try to "delete" this entity, I got this error: <pre><code>Exception [EclipseLink-6002] (Eclipse Persistence Services - 2.4.1.v20121003-ad44345): org.eclipse.persistence.exceptions.QueryException Exception Description: Aggregated objects cannot be written/deleted/queried independently from their owners. Descriptor: [RelationalDescriptor(br.com.germantech.ecf.dominio.modelo.produto.Combustivel --> [])] Query: DeleteObjectQuery(br.com.germantech.ecf.dominio.modelo.produto.Combustivel@1a7cbdd) </code></pre> Actually, I do not remove the entity from database. as seen, I have and customizer which just set the product as inactive, like this <pre><code>public class ProdutoCustomizer implements DescriptorCustomizer { public void customize(ClassDescriptor descriptor) { descriptor.getQueryManager().setDeleteSQLString("update Produto set ativo = false where id = #ID"); } </code></pre> so, what am I missing here? the <code>Combustivel</code> MUST be embedded, I can't change that Edit The stacktrace <pre><code>[EL Warning]: 2013-03-21 10:59:34.659--UnitOfWork(12940738)--Thread(Thread[main,6,main])--Local Exception Stack: Exception [EclipseLink-6002] (Eclipse Persistence Services - 2.4.1.v20121003-ad44345): org.eclipse.persistence.exceptions.QueryException Exception Description: Aggregated objects cannot be written/deleted/queried independently from their owners.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
