Re: [rules-users] explanation on drl usage

Hi there, Best to understand your needs before suggesting, but working simply on syntax, if you are using trunk, you can do this: rule "findRelevantResult" when $resultat : Resultat( ( results.size() > 0 ) ) then end rule "testPsaId" when

Re: [rules-users] LHS Dao Calls

Rahul, Yes, this is new to 3.1M2 (trunk). You can call methods with parameters if you use predicates. But it is important to note you must be careful when doing it, because the return value must be time-constant, and there are perf impacts if you abuse it. []s Edson 2007/4/6, Rahul Phad

Re: [rules-users] Are all predicates evaluated each time?

The answer to your question is not simple. Basically, the constraint evaluation will follow a priority order, in the following way: 1) all alpha constraints are evaluated 2) all beta indexable constraints are evaluated 3) all beta non indexable constraints are evaluated Inside each of the

Re: [rules-users] LHS Dao Calls

Sunjay, Methods called by using the "from" CE are expected to return a collection of VO's, not boolean results. For your case, probably what you want is something like: ItemVo( statusCode : itemStatusCode != null, (* itemValidationDao.isValidItemStatus(statusCode)*) ) A predicate allow yo
