[rules-users] no-loop & lock-on-active clarification

I tried following rules as given below and result are:(assumes facts which I tried are qualified for both rules) 1. when lock-on-active used with both rule, only rule "1 precondition" got executed for all facts. 2. when no-loop used with both rules, infinite loop 3. when lock-on-active for rule "1 precondition" and no-loop for rule "1 main condition" used, both rule got fired correctly. 4. for vice versa of 3 scenario, only rule "1 precondition" got executed for all facts. Can someone please clarify about this scenario and also diff between no-loop & lock-on-active? when we should use one and when should not? I went thru documentation and still could not understand the difference. public class Foo { private Set<String> preConditionPassedRules ; private Integer f1; private Integer f2; } rule "1 precondition" salience 100 when foo : Foo( f1 != null && f2 != null) then foo.addPreconditionPassedRule("1 precondition"); update(foo) end rule "1 main condition" salience 100 when foo : Foo( preconditionPassedRule contains "1 precondition",f1 > 1000,f2 < 1000) then #actions end -- View this message in context: http://www.nabble.com/no-loop---lock-on-active-clarification-tp20443036p2...
