It's not, but can easily be. I just tried that, though, and the same exception happened.
DRL attached. It's an old attempt to update the classic monkeys and bananas example to make it a bit more interesting: wandering monkeys, stacking blocks, a bit of world physics, stuff like that. I haven't touched it for several years and wanted to update it with new drools features for a presentation I'm doing on Tuesday. I was able to use the new parser features to eliminate a ton of evals, and would like to put traits and propSpecific features in.
And just to confuse things a bit I have a question about propSpecific. :) Is it possible to annotate a method to indicate that it changes properties on a different object type other than itself? Take the "monkey_finds_block" rule as an example. The Monkey.setHolding() method modifies the thing that's being held. It would be great if I could annotate Monkey.setHolding() to indicate that it not only modifies Monkey.holding, but also Entity.location and Entity.holds.
