The current design of MessageContext is a singleton pattern that does not support any type of decoration and/or delegation chain. This task involves developing a MessageContextWrapper class to the Liferay Faces Util project in order to support this. It also involves refactoring the MessageContextLiferayImpl class in the Liferay Faces Portal project to support decoration/delegation.
