To the point, you expected that the converter's properties are set every time a datatable row is rendered. This is indeed not true. JSF will create only one converter instance per component when the view is to be built, it will not create/reset the converter each time the row is rendered. There are several ways to get it to work. <ul> <li>Pass the dynamic attributes as <code><f:attribute></code> of the component and let the <code>Converter</code> intercept on that. You can find an example here: <a href="https://stackoverflow.com/questions/7122460/jsf-convertdatetime-with-timezone-in-datatable/7123153#7123153">JSF convertDateTime with timezone in datatable</a>. This can then be used as <pre class="lang-html prettyprint-override"><code><h:outputText value="#{item.balanceDate}"> <f:converter converterId="isoDateTimeConverter" /> <f:attribute name="pattern" value="#{item.pattern}" /> </h:outputText> </code></pre> <hr></li> <li>Use an EL function instead of a <code>Converter</code>. You can find an example here: <a href="https://stackoverflow.com/questions/2378826/facelets-and-jstl-converting-a-date-to-a-string-for-use-in-a-field/2381443#2381443">Facelets and JSTL (Converting a Date to a String for use in a field)</a>. This can then be used as <pre class="lang-html prettyprint-override"><code><h:outputText value="#{mh:convertIsoDate(item.balanceDate, item.pattern)}" /> </code></pre> <hr></li> <li>Bind the converter and datatable's <code>DataModel</code> as a property of the same managed bean. This way you will be able to set the converter's properties based on the row data before returning it. Here's a basic kickoff example based on standard JSF components and standard <code>DateTimeConverter</code> (it should work equally good on PrimeFaces components and with your custom converter): <pre><code><h:dataTable value="#{bean.model}" var="item"> <h:column> <h:outputText value="#{item.date}" converter="#{bean.converter}" /> </h:column> </h:dataTable> </code></pre> with <pre><code>@ManagedBean @ViewScoped public class Bean implements Serializable { private List<Item> items; private DataModel<Item> model; private DateTimeConverter converter; @PostConstruct public void init() { items = Arrays.asList( new Item(new Date(), "dd-MM-yyyy"), new Item(new Date(), "yyyy-MM-dd"), new Item(new Date(), "MM/dd/yyyy")); model = new ListDataModel<Item>(items); converter = new DateTimeConverter(); } public DataModel<Item> getModel() { return model; } public Converter getConverter() { converter.setPattern(model.getRowData().getPattern()); return converter; } } </code></pre> (the <code>Item</code> class is just a bean with two properties <code>Date date</code> and <code>String pattern</code>) this results in <blockquote> 23-09-2011 2011-09-23 09/23/2011 </blockquote> <hr></li> <li>Use <a href="http://omnifaces.org" rel="nofollow noreferrer">OmniFaces</a> <code><o:converter></code> instead. It supports render time evaluation of EL in the attributes. See also <a href="http://showcase.omnifaces.org/taghandlers/converter" rel="nofollow noreferrer">the <code><o:converter></code> showcase example</a>. <pre><code><h:outputText value="#{item.balanceDate}"> <o:converter converterId="isoDateTimeConverter" pattern="#{item.pattern}" /> </h:outputText> </code></pre></li> </ul>

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.
