Async action call from a DSL rule / ReferenceError

[snow crash]

Hi again,

Following the wiki, I tried to implement fully the example "saveToDatabase" in the DSL:

   then {

        saveToDatabase(m, function(err){

            next(new Error("Something went BOOM!"));

        });

I have added in the main node.js code then I manage the session the function saveToDatabase(facts, engine, next) {...} but when executing I've got the following error :

[ReferenceError: saveToDatabase is not defined]

Did I forget anything ?

As a workaround I emit an event:

emit("saved", m);

 But in the case I'd like to read data from the database to get parameters for the rule, I guess the good pattern is really to call an async action.

Thanks !
