Hello
I'd like to report a (possible) bug,
I've tried to run this on the latest version of drools (4.0.3) but I get an error:
applyOrTransformation could not find transformation for parent 'OR' and child 'OR'
java.lang.RuntimeException: applyOrTransformation could not find transformation for parent 'OR' and child 'OR'

this is what the rule looks like:

wine : Wine(color == "red")
or
(
    cheese : Cheese(smelly == "yes")
    and
        (
            person : Person(height == 12, fovouriteCheese == cheese)
            or
            person : Person(height == 13, fovouriteCheese == cheese)
        )
)

the rule looks perfectly sensical to me. If I change it to this (which, btw. looks non-sensical)
wine : Wine(color == "red")
or
(
    cheese : Cheese(smelly == "yes")
    or
        (
            person : Person(height == 12, fovouriteCheese == cheese)
            and
            person : Person(height == 13, fovouriteCheese == cheese)
        )
)


I'm not saying the second one shouldn't work(I fail to make the sense of it however), but it looks to me, the first one should.
Am I wrong, or is this really a bug?
