I tried these cases:
{code}
public Set<SignOffStatus> getStatuses()
public List<SignOffStatus> getStatuses()
public Collection<SignOffStatus> getStatuses()
public SignOffStatus[] getStatuses()
{code}
In all cases both stat.name() and stat.label worked ok if statuses is invoked as
#\{bean.statuses}.
If statuses is invoked as #\{bean.getStatuses()}, then the first 3 cases (collections)
work ok, and the case of array does not work.
[~andrei.ivanov], please specify what is return type of getStatuses() in your case, is it
an array?
Is it an acceptable workaround to use #\{bean.statuses} ?
Anyway, the case I have reproduced is a bug indeed, though it is not specific to enums
only, but to any bean classes, so that I would open a new issue for it.

 EL Knowledge Base Problem with enums
 ------------------------------------

                 Key: JBIDE-21323
                 URL: https://issues.jboss.org/browse/JBIDE-21323
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: jsf
    Affects Versions: 4.3.0.Final
         Environment: Eclipse Mars.1 (4.5.1), Primefaces 5.x
            Reporter: Andrei Ivanov
            Assignee: Viacheslav Kabanovich
            Priority: Minor
             Fix For: 4.4.x

 Enum properties and method are not recognized:
 In this case, {{label}} is recognized and shows up in the completion suggestions, but
{{name()}} is not and marked as unrecognized.
 {code:xml}
 <p:dataTable value="#{page.dataModel}" var="managerData"
lazy="true"
 rowStyleClass="#{managerData.status.label}
labor-protection-#{managerData.status.name().replace('_',
'-').toLowerCase()}">
 ...
 </p:dataTable>
 {code}
 {code:java}
 public enum SignOffStatus {
 	VALID("Valid"),
 	ALMOST_EXPIRED("Almost expired"),
 	EXPIRED("Expired");
 	private final String label;
 	private SignOffStatus(String label) {
 		this.label = label;
 	}
 	public String getLabel() {
 		return label;
 	}
 }
 {code}
 In a different page:
 {code:xml}
 <p:selectOneMenu value="#{instancePage.instanceCriteria.status}">
 	<f:selectItem itemLabel="--select--" itemValue="#{null}" />
 	<f:selectItems value="#{appBean.getStatuses()}" var="stat"
itemLabel="#{stat.label}" />
 </p:selectOneMenu>
 {code}
 The enum has a {{getLabel()}} as the one above, but in this context it's not
recognized ({{"label" cannot be resolved}}).
