[rules-users] access to in working memory generated objects

Hi, I want to use rules which shall generate as a consequence a new java object. The GUI of my application shall display the new generated objekt. but how can the GUI of my application get informed by the rule engine that it has generated a new object (Warning)? And how the GUI or any other java component can access this new generated object from outside? rule "Value below threshold" when FactX ( property < threshold) then insert(new Warning( "Under threshold" ) ); end rule "Value above threshold" when FactX ( property >= threshold) then insert(new Warning("Threshold exceeded" ) ); end regards Thomas
