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. 
[~andrei.ivanov], please specify what is return type of getStatuses() in your case?



was (Author: scabanovich):
I tried these cases:
{code}
public Set<SignOffStatus> getStatuses()
public List<SignOffStatus> getStatuses()
public Collection<SignOffStatus> getStatuses()
public SignOffStatus[] getStatuses()
{code}
In the first 3 cases both stat.name() and stat.label worked ok. In the case of array they did not work or rather they suggested to use syntax stat.next().label.
Yes, this is a bug, though it is not specific to enums, it involves all beans.
[~andrei.ivanov], please specify what is return type of getStatuses() in your case, is it an array?
Can we move the array problem into a separate issue, because it is not specific to enums?

> 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}}).
