Has anyone here successfully used Enum in the guided editor in Guvnor?

I am trying to build a patter with the following pseudo condition but could not get the Enum list displayed in the drop down of the Enum:

"There is an Event with Event.type (Enum EventType) equal to EventType.someType".

Here, someType is one of the enum defined in EventType.java.

Event.java has getType() method returns EventType.

Everything seems working fine, exception in the drop down of EventType, there is no enum defined. It only has the standard API from Enum listed there.

Any input is appreciated.

Thanks

Sean
