    <p>You'd need to provide the whole <code>Language</code> objects as both the available items and the selected items. You also need to create a <code>Converter</code> which converts between the <code>Language</code> object and <code>String</code>, this is mandatory because HTML output and HTTP request parameters are one and all <code>String</code>.</p> <p>Assuming that your <code>Language</code> object has two properties <code>code</code> and <code>name</code> and that you've an application scoped bean which look like this:</p> <pre><code>@ManagedBean @ApplicationScoped public class Data { private List&lt;Language&gt; languages; @PostConstruct public void init() { languages= new ArrayList&lt;Language&gt;(); languages.add(new Language("en", "English")); languages.add(new Language("hi", "Hindi")); languages.add(new Language("te", "Telugu")); // ... } public List&lt;Language&gt; getLanguages() { return languages; } } </code></pre> <p>Then you can use it as follows:</p> <pre><code>&lt;h:selectManyCheckbox value="#{bean.selectedLanguages}" converter="languageConverter"&gt; &lt;f:selectItems value="#{data.languages}" var="language" itemValue="#{language}" itemLabel="#{language.name}" /&gt; &lt;/h:selectManyCheckbox&gt; </code></pre> <p>with this bean</p> <pre><code>@ManagedBean @ViewScoped public class Bean { private List&lt;Language&gt; selectedLanguages; // ... } </code></pre> <p>and this converter</p> <pre><code>@FacesConverter("languageConverter") public class LanguageConverter implements Converter { @Override public String getAsString(FacesContext context, UIComponent component, Object object) { return ((Language) object).getCode(); } @Override public Object getAsObject(FacesContext context, UIComponent component, String submittedValue) { List&lt;Language&gt; languages = (List&lt;Language&gt;) context.getApplication().evaluateExpressionGet(context.getELContext(), "#{data.languages}", List.class); for (Language language : languages) { if (language.getCode().equals(submittedValue)) { return language; } } return null; } } </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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
