Hi again, Is there a way to "decorate" a Java instance with a JavaScript object? So that the JS object gets a shot at the messages sent to it before delegating to the Java object. By a bit of Rhino hacking perhaps? Or is at already available? (Note that this would be different from JavaAdapter, at least I think so. Instantiate Java class, hook in JS object on the instance to "preprocess" messages sent to the Java instance.) Best regards, Micke
