    <p>I read on SO some QA about the same component, but I feel I'm missing something, because I am one step behind. I can't even make the page open when using the primefaces autocomplete component in it. The snippet for it is:</p> <pre><code>&lt;p:autoComplete value="#{indirizzoCtrl.selectedCodiceNazione}" completeMethod="#{indirizzoCtrl.completeNazione}" var="nazione" itemLabel="#{nazione.nome}" itemValue="#{nazione.codiceNazione}" /&gt; </code></pre> <p>Nazione is a Pojo class where <code>CodiceNazione</code> and <code>Nome are</code> two String field (with getter and setter for sure). <code>completeNazione</code> is a method on the ManagedBean that returns <code>List&lt;Nazione&gt;</code>. Looking at BalusC explanation <a href="https://stackoverflow.com/a/7653775/333223">here</a>, it seems to me that i don't need any converter involved, because both itemValue and value attributes are mapped to string property. Anyway, when I just open the page containing this autocomplete snippet, it crashes with this error:</p> <pre><code>javax.el.PropertyNotFoundException: /Cliente/Indirizzo.xhtml @23,56 itemValue="#{nazione.codiceNazione}": itemValue="#{nazione.codiceNazione}": Property 'codiceNazione' not found on type java.lang.String </code></pre> <p>Why this is happening? I really can't get it. The method completeNazione hasn't even called yet, so it shouldn't know any <code>Nazione</code> yet. What's wrong with it?</p> <p><strong><em>Edited:</em></strong> Following the suggestion, I tried to add a converter, but I still get the same error. Here's my converter:</p> <pre><code> public class NazioneConverter implements Converter { final static Logger log = Logger.getLogger(NazioneConverter.class); @Override public Object getAsObject(FacesContext context, UIComponent component, String value) { if (value.trim().equals("")) { return null; } else { try { IndirizzoRepository ir = new IndirizzoRepository(); List&lt;Nazione&gt; nazioni = ir.getNazioneByName(value); if (nazioni.size()==1) return nazioni.get(0); else throw new Exception(); } catch (Exception e) { String msg = "Errore di conversione"; log.error(msg, e); throw new ConverterException(new FacesMessage(FacesMessage.SEVERITY_ERROR, msg, "Non è una nazione conosciuta")); } } } @Override public String getAsString(FacesContext context, UIComponent component, Object value) { if (value == null || value.equals("")) { return ""; } else { return String.valueOf(((Nazione) value).getNome()); } } } </code></pre> <p>now the component in the view looks like:</p> <pre><code>&lt;p:autoComplete value="#{indirizzoCtrl.indirizzo.nazione.codiceNazione}" completeMethod="#{indirizzoCtrl.completeNazione}" var="nazione" itemLabel="#{nazione.nome}" converter="#{nazioneConverter}" itemValue="#{nazione.codiceNazione}" forceSelection="true" /&gt; </code></pre> <p>But still don't working. The converter is not even invoked: I registered it in my faces-config.xml file. I also tried itemValue="#{nazione}" as in the primefaces showcase but the problem became the <code>ItemLabel</code> attribute, mapped to <code>nazione.nome</code>. What am I doing wrong?</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.
