Re: [rules-users] How can I iterate through the ArrayList
You may have to phrase your question more accurately in order to get an answer. Do you want the rule to fire if some, or if all, "value" fields of the AwaitingAction have some value? Once or for each AwaitingAction? Or do you want it to fire once if at least one, or if all, AwaitingActions of all AwaitingActionLists have a field "value" with some specific value? Also, would you consider inserting also the AwaitingAction objects as facts, not only the AwaitingActionList? -W On 13/11/2013, Govind J.

Re: [rules-users] How to use type-safe enums in rule condition
We use drools for validation rules in our application. Some of these rules are dependent on which CRUD operation is being performed at the time, so as part of our validation aspect we insert a CrudMode enum with the current action (by annotating the advised method). e.g. @Validate(validators = BusinessRulesValidator.class, mode = CREATE) public void create(@DTO SomeDTO incomingDto) In our rules we can then go: CrudMode(this == CrudMode.CREATE) The second way we use it (and this one I don't like so much) is that our validation aspect runs both before and after a method (PRE and POST). We use an agenda-group to to indicate which phase a rule should be included which works fine, however we were finding that some conditions were relatively expensive which had performance implications. Our solution was to also include a ValidationPhase enum as a fact and use that to short-circuit the rules. I reckon there is probably a better way to achieve this however we didn't spend a lot of time thinking about it. cheers Steve --- Steven Williams On Thu, Nov 14, 2013 at 12:40 AM, Wolfgang Laun wrote: > Just curiosity. > > On 13/11/2013, Steven Williams wrote: > > I use something like the following in rules to good effect: > > > > Country( this == Country.USA ) > > Granted, you can add any number of attributes to an enum so that it's > just another way of writing a static set of bean objects.

Re: [rules-users] Problem in writing rule and apply DSL
Of course, you can just bypass the built in “-“ processing.
[condition][]There is a Person = $p: Person()
[condition][]The person is aged over "{age}” =$age: Integer(this > {age}) from
$person.age
Of course that does require that you’re careful about writing the DSLR, so that
you always bind a variable to Person() before using a phrase which expects that
variable to exist.
btw … Apologies, but Integer(this > {age}) is almost certainly buggy syntax. I
can’t remember off-hand the best way to do that comparison. :-/

[rules-users] "distinct" operator in a query
Hello guys, I make a very simple question, especially for a curiosity. I have this query: query "QuerySelected" $result: Person( identifierCode == "ABCDEF12H45S100A" ) $y: YearData( id == $result.identifierCode ) exists Vehicle( ) from $y.vehicles end With this query i get two equal person results because there are two annual that matches with condition. There is a simple way in drools to apply "distinct" operator or avoid this behaviour.

I suggest you redesign your DSL with phrases like
There is a {Fact}
and a {FactA} from {FactB}'s {attribute}
Users would have to write these in individual lines. Then, adding the
"- with" doesn't create a problem.
Other than this, I don't see much hope for getting the constraint
where it belongs. Consider that *you* think right *now*, that it ought
to be in the first pattern, but s.o. else might want it in the middle
