[rules-users] activationCancelled() not being executed?
Hi! I'm using a JTable to display rules that have been activated. My goal is to have the table display a set of activations ordered by their salience. The user should then choose which one of them to fire (if you want to know why, be invited to read the background). Of course this makes only sense as long as the activations are valid. Rules whose activation has been cancelled should still be displayed, but in a different style (like greyed out). In order to accomplish this, I want to use an implementation of the AgendaEventListener-interface, implementing the activationCancelled()-method. The Listener itself works, as I use the activationCreated()-method to add the rule as a row to my table (which works fine). Unfortunately the activationCancelled()-method doesn't seem to be executed at all! I assume that I have a fundamental misunderstanding of what should trigger an activationCancelled() event? Background: (just if you're curious...) I'm working as a PhD student in physics at the CERN international high-energy physics laboratory, for the ATLAS experiment. As a member of the Detector Control System (DCS) group, I'm going to write an expert system in order to assist the shift crew with the detector operation. The operation of the detector is a difficult task, because more than 7 parameters (like voltages, currents and temperatures) have to be controlled. A Finite State Machine (FSM) computes a defined and limited number of states from the given parameters (like ON, OFF, STANDBY,...). I'm going to synchronize the expert system application to ERROR states of the FSM, in order to extract the relevant parameters from the system (as it would be impossible to feed all parameters into the XPS all the time). This is handled by quite some control rules that decide which data has to be requested, released and so on. Once all necessary data has been received, this might lead to activations of the (more interesting) user rules. Those rules have an explanatory character like The temperature of this XYZ is too high, so please try ABC. For a given set of facts I assume more then one rule to be activated. Whilst the rule engine should take care of the execution (firing) of all control related rules, the execution of the user rules should be under direct user control. Displaying all activations in a GUI will allow the user to pick one (try it) and rate it (the proposed solution solved the problem yes/no). Changing the rules salience according to the answer, will allow the system to dynamically reflect the current system status. (Rules that are related to broken connections / wrongly connected cables are likely to be found at the beginning of the experiment but hopefully only on rare occasion later on.) In order to ensure that no information is lost during the absence of DCS experts (which will not always be around), a log file should be written for each major FSM-ERROR. At the moment the WorkingMemoryFileLogger seems to be predestined for this job. This way I hope to collect large amounts of ERROR data during the initial phase of the experiment that helps to extract rules for numerous error conditions. This will become especially handy, as such errors have a tendency to come back, even if the original detector experts are gone for years... -- View this message in context: http://www.nabble.com/activationCancelled%28%29-not-being-executed--tf4348054.html#a12387991 Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hi all, I have a HashTable dawned by a thread T1, another thread T2 take this HashTable and give it to the working memory as assertion. what happens if T2 and JRools try to access to the HashTable?

Re: [rules-users] problem with threads
Raffaele, Hashtable is synchronized already, and so you will not have any problem. But answering your question, drools does not start any inner thread. It will simply use the thread calling its methods, so the default java synchronization mechanisms apply.
