There is a quite Nasty bug in AceOO, that took me a while to pinpoint.

in Class:init() we have :

if parent.interfaces then
	if newclass.interfaces then
		...
	else
		newclass.interfaces = parent.interfaces
	end
end

but in validateInterface() we have :

	object.class.interfaces[interface] = true

Ouch ! So if you have inheritance and the child class support an interface, then the parent is marked as supporting the interface !

The fix is easy, when you have understood this. Replace :

	newclass.interfaces = parent.interfaces

by

	newclass.interfaces = {}
	for k,v in pairs(parent.interfaces) do newclass.interfaces[k] = v end

while I'm here, talking about AceOO. There has been a recent change in AceOO that makes the following example fail, which I think is a bug :

local oo = AceLibrary("AceOO-2.0")
local I = oo:Interface{foo = "string"}

local C = oo:Class(I)

function C.prototype:init()
	self.foo = "bar"
	C.super.prototype.init(self)
end

local o = C:new()
