    copied!<p>I have a problem with i18n enums in my JSF application. When I started, I had enums with the text defined inside. But now, I have keys tied to message bundles in the enum.</p> <p>Example one of my enums:</p> <pre><code>public enum OrderStatus implements CustomEnum { PENDING("enum.orderstatus.pending"), CANCELED("enum.orderstatus.canceled"); /** * key in message bundle */ private String name; OrderStatus(String name) { this.name = name; } @Override public String getName() { return name; } } </code></pre> <p>In the view layer, I use something like:</p> <pre><code>&lt;!-- input --&gt; &lt;h:selectOneMenu value="#{order.status}"&gt; &lt;f:selectItems value="#{flowUtils.orderStatuses}"/&gt; &lt;/h:selectOneMenu&gt; &lt;!-- output --&gt; &lt;h:outputText value="#{order.status}"/&gt; </code></pre> <p>and in Java:</p> <pre><code>public class FlowUtils { public List&lt;SelectItem&gt; getOrderStatuses() { ArrayList&lt;SelectItem&gt; l = new ArrayList&lt;SelectItem&gt;(); for(OrderStatus c: OrderStatus.values()) { // before i18n // l.add(new SelectItem(c, c.getName())); // after i18n l.add(new SelectItem(c, FacesUtil.getMessageValue(c.getName()))); } return l; } } public class FacesUtil { public static String getMessageValue(String name) { FacesContext context = FacesContext.getCurrentInstance(); return context.getApplication().getResourceBundle(context, "m").getString(name); } } </code></pre> <p>It worked well, but when I needed to output <code>#{order.status}</code>, I needed to convert it. So I implemented a converter, but got in trouble with conversion of <code>String</code> to <code>Object</code> in the <code>getAsObject()</code> method.</p> <p>web.xml:</p> <pre><code>&lt;converter&gt; &lt;converter-for-class&gt;model.helpers.OrderStatus&lt;/converter-for-class&gt; &lt;converter-class&gt;model.helpers.EnumTypeConverter&lt;/converter-class&gt; &lt;/converter&gt; </code></pre> <p>Java:</p> <pre><code>public class EnumTypeConverter implements Converter { @Override public Object getAsObject(FacesContext context, UIComponent comp, String value) throws ConverterException { // value = localized value :( Class enumType = comp.getValueBinding("value").getType(context); return Enum.valueOf(enumType, value); } @Override public String getAsString(FacesContext context, UIComponent component, Object object) throws ConverterException { if (object == null) { return null; } CustomEnum type = (CustomEnum) object; ResourceBundle messages = context.getApplication().getResourceBundle(context, "m"); String text = messages.getString(type.getName()); return text; } } </code></pre> <p>I'm entangled now with that. Anybody know how to internationalize multiple Enums efficiently?</p>
