Hi Alex, my understanding is that ?c are not the same. They would be the same if they were in the same pattern, but here it is not the case. Try to view this rule (eg. with view command) and you will see that each ?c get some prefixes to make them unique. I hope I'm right, Waldek

Although I only have 5 rules, I get into a strange loop. Here is the rule that fires continuously: (defrule ASP1 (OrmedContext (readyToRun TRUE) (task "script") (OBJECT ?c) ) (CompleterResponseElement (ormedContext ?c) (key "ASP") ) => (bind ?s (new OrmedScript "ASP")) (call ?c setSelectedScript ?s) (call ?s addInstruction (new OrmedScriptInstruction "Aspirine Cardio (100mg)" FALSE TRUE TRUE TRUE)) (call ?s addInstruction (new OrmedScriptInstruction "Aspirine 500mg" FALSE TRUE TRUE TRUE)) (call ?s addInstruction (new OrmedScriptInstruction "Aspirine 1000mg" FALSE TRUE TRUE TRUE)) ) My understanding is that ?c is the same. It is the way I found to avoid the problem of bean properties which cant be null. Here OrmedContext has a completerResponseElement, but it can be null. Therefore, I do things the other way round: When I set a completerResponseElement to my OrmedContext, I set the ormedContext in CompleterResponseElement and The latter is definstanced. My rule means: When a OrmedContext is readyToRun and task is script and has a CompleterResponseElement with key is ASP Then create a new OrmedScript, set it to OrmedContext then add three instructions. OrmedContext, CompleterResponseElement, OrmedScript are definstanced (in the Java code). Only OrmedContext is dynamic. When I add the new OrmedScript to OrmedContext I do: undefinstance the previous one if it is not null assign the ormedContext property to it definstance the new selectedScript fire property change for the selectedScript in OrmedContext I am really puzzled because it seems so simple!
