JSF and Enums

Tuesday, July 28th, 2009

Reading on the web, I found a lot of approaches to use Enums with JSF. But to be honest, I found most of them quite overdone. People are working a lot with own converters, et cetera.

But on my try, it went all without that. What I did:

- just refer to the Enum type property in the bean/object

	<h:outputText value="Art des Projekts" />
	<h:selectOneMenu value="#{projectsBean.selectedObject.type}"
		styleClass="inputfield">
		<f:selectItem itemLabel="-- not assigned --" />
		<f:selectItem itemLabel="------------" />
		<f:selectItems	value="#{optionProvider.typeOptions}" />
	</h:selectOneMenu>

- and provide al list of Enum values

	public final List getTypeOptions() {
		List typeOptions = new ArrayList();
		for (ProjectType pt : ProjectType.values()) {
			typeOptions.add(new SelectItem(pt, pt.toString().toLowerCase()));
		}
		return typeOptions;
	}

That’s it – working without any problem.

But now I am wondering, what the reason is, why all the other people make so much effort? Did I miss something? Or is my case just to trivial?
