Access
custom controller-defined enum in custom component
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'}" />
