JESS:Modular deffacts problem
Hi I'm having a problem with deffacts and modules I was hoping someone could help me out with. I'm trying to use deffacts with a specific module, but am having some problems changing out of that module once the deffacts has taken place. At present, I'm doing the following (although I've simplified the code here, the sense remains the same): (defmodule ONE) (defmodule TWO) (defmodule THREE) (set-current-module MAIN) (deftemplate TWO::template-for-module-two (slot slot1) ) (deffacts some-facts (TWO::template-for-module-two (slot1 value1)) (TWO::template-for-module-two (slot1 value2)) ) ;;; some business logic rules (reset) Once the code has been parsed into the Rete [ using executeCommand(String)] I then subsequently assert some shadow fact objects before running the rete. The problem is that the shadow facts are asserted into the TWO module rather than the MAIN module as I would like them to be. It seems my call to set-current-module is being overridden by the deffacts construct asserting facts straight into the TWO module. Is there a way around this so that once the reset command has been called, the focus shifts back to MAIN automatically? Any help would be gratefully received.

At present, I'm doing the following (although I've simplified the code here, the sense remains the same): I'm afraid you've simplified things a little bit too much. The important points are 1) when and where the defclass for your Java objects is being done, 2) exactly how the object is being put into working memory, and 3) what version of Jess you're using. Jess 7.0b4 was released just today, and it fixes a bug in earlier 7.0 releases related to definstances in the presence of multiple modules, although the symptoms don't sound precisely right. - Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National LabsFAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
