    <p>I've created a picklist via PrimeFaces. Now i want to handle the selected items which are listed in the target list when i click the commandButton.</p> <p>I want to pass the data through the controller and store them in my database. But everytime i call the function duallist.getTarget() it's empty.</p> <p>I've crated a foreach-Loop where i want to select all items in the target list:</p> <p><strong>Controller (Bean):</strong></p> <pre><code>private List&lt;DTOAktivitaet&gt; source = new ArrayList&lt;DTOAktivitaet&gt;(); private List&lt;DTOAktivitaet&gt; target = new ArrayList&lt;DTOAktivitaet&gt;(); private List&lt;DTOAktivitaet&gt; zwischen = new ArrayList&lt;DTOAktivitaet&gt;(); public void speicherAktiZug() { DTOAktivitaet aktivitaet_vorgaenger = null; for (DTOAktivitaet item : controller.getAktivitaeten()) { if (item.toString().equals(selected)) { aktivitaet_vorgaenger = item; } } for (DTOAktivitaet aktivitaet : zwischen) { try { dao.aktiZugAkt(aktivitaet_vorgaenger, aktivitaet); } catch (SQLException e) { e.printStackTrace(); } catch (ClassNotFoundException e) { e.printStackTrace(); } } } public AktiListController() { for (DTOAktivitaet ak : controller.getAktivitaeten()) { source.add(ak); } aktis = new DualListModel&lt;DTOAktivitaet&gt;(source, target); zwischen = aktis.getTarget(); } </code></pre> <p><strong>JSF:</strong></p> <pre><code> &lt;h:form id="form" name="formular"&gt; &lt;h:outputText id="aktivitaet" value="#{aktiListController.selected}" /&gt; &lt;p:pickList id="pickList" value="#{aktiListController.aktis}" var="aktivitaet" itemValue="#{aktivitaet}" itemLabel="#{aktivitaet}" converter="aktivitaetsConverter" showSourceControls="true" showTargetControls="true" /&gt; &lt;h:commandButton action="#{aktiListController.speicherAktiZug}" value="Aktivität-Abhängigkeit anlegen" class="commandButton"&gt; &lt;/h:commandButton&gt; &lt;/h:form&gt; </code></pre> <p><strong>Converter:</strong></p> <pre><code>@EJB public class AktiListConverter implements Converter { private InitialisierungController controller = InitialisierungController .getInstance(); DTOAktivitaet aktivitaet = new DTOAktivitaet(); String name = ""; @Override public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) { for (DTOAktivitaet item : controller.getAktivitaeten()) { if (item.toString().equalsIgnoreCase(arg2)) { this.aktivitaet = item; System.out.println(aktivitaet); return aktivitaet; } } return null; } @Override public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) { this.aktivitaet = (DTOAktivitaet) arg2; return this.name = aktivitaet.getTeambezeichnung(); } } </code></pre> <p><strong>My Problem:</strong> The target-List is empty before i want to store the items in my database.</p>

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.
