    <p>I'm using JSF 2.1 and Tomcat 7. I have the following PrimeFaces select one menu:</p> <pre><code>&lt;p:selectOneMenu id="idMarcaEdit" value="#{cfgCentraleController.selMarcaEdit}" var="p" height="250" effect="fade" converter="marcaConverter" &gt; &lt;f:selectItems value="#{cfgCentraleController.marche}" var="c" itemLabel="#{c.marca}-#{c.modello}-#{c.versione}" itemValue="#{c}"/&gt; &lt;p:column&gt; &lt;h:outputText value="#{p.marca}" /&gt; &lt;/p:column&gt; &lt;p:column&gt; &lt;h:outputText value="#{p.modello}" /&gt; &lt;/p:column&gt; &lt;p:column&gt; &lt;h:outputText value="#{p.versione}" /&gt; &lt;/p:column&gt; &lt;p:column&gt; &lt;h:outputText value="#{p.provisioning}" /&gt; &lt;/p:column&gt; &lt;/p:selectOneMenu&gt; </code></pre> <p>I have this in <code>#{cfgCentraleController}</code></p> <pre><code>private List&lt;Marca&gt; marche; private Marca selMarcaEdit; public Marca getSelMarcaEdit() { return selMarcaEdit; } public void setSelMarcaEdit( Marca selMarcaEdit ) { this.selMarcaEdit = selMarcaEdit; this.selectedCentrale.setIdRete( this.selMarcaEdit.getIdMarca()); } public List&lt;Marca&gt; getMarche() { return marche; } </code></pre> <p>It works fine, but I don't realy need the whole entity to be submitted. I just need its ID.</p> <p>I'm using OmniFaces for the converter:</p> <pre><code>import org.omnifaces.converter.SelectItemsConverter; @Override public String getAsString( FacesContext context, UIComponent component, Object value ) { Integer id = (value instanceof Marca) ? ((Marca) value).getIdMarca() : null; return (id != null) ? String.valueOf( id ) : null; } </code></pre> <p>How do I obtain only the ID of the entity in the model? </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.
