Thanks Yannick De : DECOUX Yannick [mailto:[email protected]] Envoyé : mardi 5 avril 2011 07:52 À : [email protected] Objet : [rules-users] Simple rule and Query Hi, I'am trying to use Query and i'am facing a little problem : Given this simple rule : package be.test.person import be.test.person.* query "get adult" adult : Adult( ) end query "get person" person : Person( ) end declare Adult name : String end rule "A person over 18 is an adult" when Person( age >= 18) then System.out.println("Adult detected"); insert(new Adult()); end Lets suppose one Person over 18 is inserted inside the working memory, the result of the query « get adult » is 0 (Please note the declaration of Adult type inside the rule) If I create a Java class Adult (commenting the one in the .drl file) and then run the query again, this time the result is 1 Also, the signature of org.drools.runtime.rule.WorkingMemory.getQueryResults(String) says IllegalArgumentException when query is not found in the KnowledgeBase. This doesn't seems to be the case when I use a fake query name. I'am using drools 5.1.1 Any idea on this ? Thanks
