We cannot reference the enum DIRECTLY since the enum itself is not visible to the page and you can’t make it a property.

EXAMPLE:

Apex class:

global with sharing class My_Controller {

public Case currCase {get; SET; }

public enum StatusValue {RED, YELLOW, GREEN}

public StatusValues getColorStatus() {

return StatusValue.RED; //demo code - just return red

}

}

Visualforce page:

<apex:image url='stopsign.png' rendered="{!colorStatus == StatusValue.RED}"/>

Above code snippet will throw error something like “Save Error: UNKNOWN property‘My_Controller.statusValue’”

Resolution:

Add below method in Apex CONTROLLER:

public String currentStatusValue { get{ return getColorStatus().name(); }}

and change Visualforce code to

<apex:image url='stopsign.png' rendered="{!currentStatusValue == 'RED'}" />
