So I have an object with a map like follows: protected ConcurrentMap<String, Double> accumulations = new ConcurrentHashMap<String, Double>();
I wrote a convince method on the class that will look up the value in the map and add to it if it exists and if not there will put it in the map: @Modifies({ "accumulations " }) public void addToAccumulation(String code, long volume) { if (accumulations .containsKey(code)) { Double value = accumulations .get(code) + volume; accumulations .put(code, value); } else { accumulations .putIfAbsent(code, new Double(volume)); } } I have a rule to listen on the change of this filed on the object(i.e accumulations["someCode"]!=null) but when I modify the object the rule doesn't fire. I have added @PropertyReactive to the Object and build the kbase as follows: Properties props = new Properties(); props.setProperty("drools.dialect.java.compiler", "JANINO"); KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory .newKnowledgeBuilderConfiguration(props); config.setOption(PropertySpecificOption.ALWAYS); Any insight into why this may not work? -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-5-Property-Reactive-on-Maps-tp4026782.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
