Hey,
What is the cachedResult for? When trying to find them with the debugger (by looking for messages that have hasCachedResult true) I don't find any.
And how to get the intermediate result in a message chain? For example I have 1 +(1) +(1) -(1) +(1) +(1) and I wan't to get the result of the -(1) when it flies along in the debugger, how do I get its return value?

Cheers Jan
