    <p>Of five options in a selectOneMenu I chose the second option and persisted the entity. On edit the persisted entity selectOneMenu always has the last option as its value.</p> <p>For example,</p> <pre><code>&lt;h:selectOneMenu value="#{userHome.user.leader}"&gt; &lt;f:selectItems value="#{userHome.availableLeaders}" var="leader" itemLabel="# {leader.name}" itemValue="#{leader}"/&gt; &lt;/h:selectOneMenu&gt; </code></pre> <p>where availableLeaders is a list of users populated @PostConstruct method.</p> <p>I am expecting the selectOneMenu to have the second option(chosen) on edit.</p> <pre><code>@FacesConverter(forClass = User.class, value = "userConverter") public class UserConverter implements Converter { public UserConverter() { } @Override public Object getAsObject(FacesContext context, UIComponent component, String value) { EntityManagerFactory emf = Persistence.createEntityManagerFactory("DefaultPersistenceUnit"); EntityManager em = emf.createEntityManager(); Query q = em.createQuery("select query"); return q.resultList().get(0); } @Override public String getAsString(FacesContext context, UIComponent component, Object value) { return ((User) value).getName(); }} </code></pre> <p>In User.java</p> <pre><code>public boolean equals(Object other) { if (this.getClass().isInstance(other)) { return true; } else { return false; } } public int hashCode() { HashCodeBuilder builder = new HashCodeBuilder(); builder.append(getId()); builder.append(getName()); return builder.toHashCode(); } </code></pre>

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.
