    <p>I've got classes with mappings like this:</p> <pre><code>@Entity public class CurrencyTable { @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) private Long id; @Version @Column(nullable=false) private Timestamp version; @Column(length=32, unique=true) private String refCode; @OneToMany(mappedBy="currencyTable", fetch=FetchType.LAZY, cascade = {CascadeType.ALL}) @MapKey(name="currency") private Map&lt;String, CurrencyTableRate&gt; rateMap = new HashMap&lt;String, CurrencyTableRate&gt;(); } @Entity public class CurrencyTableRate{ @Id @GeneratedValue(strategy = GenerationType.SEQUENCE) private Long id; @Version @Column(nullable=false) private Timestamp version; @Column(length=3) private String currency; @Basic private BigDecimal rateValue; @ManyToOne(optional=false,fetch=FetchType.LAZY) private CurrencyTable currencyTable; } </code></pre> <p>There is one row in CurrencyTable and three rows in CurrencyTableRate referring to the CurrencyTable in database.</p> <p>When I load CurrencyTable using HQL:</p> <pre><code>from CurrencyTable where refCode = :refCode </code></pre> <p>I get an entity with three entries in rateMap, but if I try this:</p> <pre><code>from CurrencyTable table left outer join fetch table.rateMap where refCode = :refCode </code></pre> <p>there is only one entry in rateMap.</p> <p>I looked on query generated by Hibernate and ran it manually - it returned three rows, as expected, so it seems to be a problem with mapping them after fetching. Has anyone encuntered such a problem? I use Hibernate version 3.2.6.ga and Oracle 10g</p>

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.
