I took a quick look at the spec, I didn't find much at all about Decorators with generic types. The only snippet I found was in 8.1.3, where it basically says that if the Decorated type is a parameterized type, then the delegate type has to have the same type parameters as the decorated type, otherwise it is a definition error.
It seems to me there is probably an OWB bug here, but the spec doesn't provide a lot of guidance beyond the single definition error.
