Re: [rules-users] looping over list
Hi, Maybe can you try the collect keyword? According to what I see in the documentation (4.8.3.9. Conditional Element collect) it seems to fit your needs. I'll probably give this a try: rule Select Officer ruleflow-group select_officer no-loop true salience 20 when $processInstance: WorkflowProcessInstance() $requestData: RequestData($genre : genre, $cost : cost) $sublist : ArrayList() from collect( Officer( minimumCost = $cost, $cost = maximumCost ) from $genre) then System.out.println(Hey!); List shrunkOfficersWithGenre = $sublist; end Best regards, Bruno (newbie). odelyaholiday a écrit : I have a list of officers: public static final MapString, ListOfficer officersPerGenre = new HashMapString, ListOfficer(); Where the Officer with: String name; Integer mininumCost; Integer maximumCost; in officersPerGenre I fill for each genre list of officers. In my drools: rule Select Officer ruleflow-group select_officer no-loop true salience 20 when $processInstance: WorkflowProcessInstance() $requestData: RequestData(); then System.out.println(Hey!); List officersWithGenre = (List)officers.get($requestData.getGenre()); end Now I need to shrink the officersWithGenre only to officers that $requestData.cost is between their mininumCost and maximum cost. How do I write it in drools? In java i will simply iterate over the collection. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Clearing an AgendaGroup
Hi I have a rule set with two agenda groups. I have a rule with autofocus on group1. If the rules in group1 are exhausted it activates group2 using setFocus(). rule Active second group agenda-group group1 auto-focus true salience -1 when eval(true) then drools.setFocus(group2) end Now I noticed that while executing rules from group2, rules from group1 were still being triggerd and executed. So I added this to the then clause. drools.getWorkingMemory().getAgenda().clearAndCancelAgendaGroup(group1) Alas, it made no difference. Some debugging made clear that after the then clause the stack contained only MAIN and group2. Am I missing some basic notion on agenda groups?

Re: [rules-users] Is Drools appropriate for this app scenario?
Sebastien, I have built an e-commerce site [www.stoneside.com] with some if not all of the things you are talking about. If you go there and design a product you can see the rules working. Drools is being used for: Pricing rules and discounts within a product. Rules regarding what components of a product can exist with other components. [the end-user is custom designing something to purchase] Rules determine how to display the product as the end-user designs their product. Rules generate the BOM once the user ultimately orders the product that they designed. All the rules are managed using excel spreadsheet templates. We [the developers] defined the templates and the business enters the rules into the spreadsheet. This has worked pretty well. The biggest hurdle being defining the templates correctly and populating the initial sets of rules. Some of the more complex products have at least 5K rules [across all 4 areas of rules] that needed to be defined. So, I think it is appropriate for your app scenario. You will need to think about what you need as rules and what those rule 'templates' need to look like.

Re: [rules-users] How to write a rule that fires when it matches against specific facts in working memory.
Thanks for outlining the approach, Edson. Unfortunately, I'm a newbie using drools, so I just need some clarification on what you mean by 'matchAll is your own accumulate function with the semantics you described.' ? Do you mean that I have to create a 'custom' accumulate function ? Edson, if that's the case, then I'll try to search for example of creating a custom function. When I last searched, I did find an example on the Internet, however, I don't think I found details of how to make the function available to the rules engine (is it as simple as including the jar in the classpath or do I need to take addtional steps to use Matchall in drl ?) Can you please elaborate for the benefit of a noobie ?

Re: [rules-users] Possible bug using from and or
This is an ambiguity inherent to the DRL language. This happens because
the parser has no way of knowing if the (...) following the expression
belong to the expression (i.e., is a method call, where you forgot the ,
between parameters) or if it is not part of the expression. So, we
arbitrarily decided that the parser will always consider the () in this case
as part of the expression, and if it is not a valid syntax, it will raise an
error. You found one way of breaking the ambiguity by adding () on
getAddresses, but you could also do:
( Address( ) from $person.addresses )
or add a ; at the end of the expression:
Address( ) from $person.addresses;
It is not a bug, as it is an ambiguity inherent to the language, not the
implementation, but I guess we could have better documentation on that. Just
for the curious, it is the same kind of ambiguity present on java/c++
parsers when you have nested if/else without blocks {}. Ex:
if (...)
if( ... )
...;
else
...;
Does the else above belong to the first or second if? The parser has
no way to know that, so they arbitrarily decided that in java/c++ that says
the else belongs to the closest if and my identation above is
misleading...

[rules-users] proper syntax for multiple function calls within LHS
hello,
I'm a newbie to Drools. I'm trying to write a rule that performs some math,
without resorting to a function or eval. I searched the forum but found lots
of posts on nested function calls,etc but not what I was searching for.
For simplicity, lets assume I have the following classes
public class ONE{
double A
double B
double C
}
public class TWO{
double D
double E
}
where A, B, C, D, E are themselves calculated values (apr, price at some
date, etc)
1. What does the LHS of a rule that compares A D look like?
2. What does the LHS of a rule that compares A+B C look like?
3. What does the LHS of a rule that compares A+D C look like?
I apologize in advance if this was covered already.
Thanks.
