All, I was investigating why the my rule was running into a loop, even though I had a "no-loop true". I was doing an session.update to update the fact in the working memory, the fact was updated (removed and added) in the working memory. I tried commenting the session.update and I can see that the shadow object in the working memory still got updated and reflected the latest value set within the java code. The looping has also stopped. Can some one clarify if its possible to update the object in working memory without calling the update method. -- View this message in context: http://old.nabble.com/update-a-shadow-object-in-working-memory-tp26338645...
