[rules-users] how to avaide overwrinting results in drools planner
I have 2 boxes, lets say each size of 5x5 and I have 3 items two size 4x4 and one item size is 3x3. planner initially planner assigning as follows... I - When I use 3 items 2 boxes(this produce wrong planning) item1 (4x4) --> box1 (5x5) item2 (4x4) --> box2 (5x5) item3 (4x4) --> box1 (5x5) II - When I use 2 item, result as follows...(this is correct planning) item1 (4x4) --> box1 (5x5) item2 (4x4) --> box2 (5x5) III - When I increase one more box(this is correct too) item1 (4x4) --> box1 item2 (4x4) --> box2 item3 (4x4) --> box3 you can see the test I - it is over writing the first assignment and assign the new item there in the box 1, I unable to figure it out how to solve this problem, I suspect this can be done in the score calculation rules, the problem is I do not know how to implement to avoid the overwriting assignments. thanks, - with kind regards, -- View this message in context: http://drools.46999.n3.nabble.com/how-to-avaide-overwrinting-results-in-drools-planner-tp4018277.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] RuleFlow not Found
up to drools 5.1 (more or less), the new default is jbpm flows, for rules or not. JBPM let you do what you can do with former .rf files. To be shorter : It is the same, at least seen from a ruleflow usage. Before you ask : you need to add jbpm jars to your drools runtime in order to make the flows work. Note that you can still use .rf format (editors works as well), but you still need to add jpbm jars. - Mail original - De: "abhinay_agarwal" À: rules-users@lists.jboss.org Envoyé: Mardi 26 Juin 2012 16:19:42 Objet: Re: [rules-users] RuleFlow not Found yeah !! -- View this message in context: http://drools.46999.n3.nabble.com/RuleFlow-not-Found-tp4018251p4018269.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

This is incorrect DRL syntax. You have to extract (using "from") the

you can extract measure.

Using variables bound to the List fields:

$olt: OrderLineType( $measures: measures ) from $orderLineList
not Measure( measure < 12 ) from $measures

You'll *have* to add a class name up front, e.g.

Re: [rules-users] Write Assumptions for NESTED List
Laune,
i need to know if this form is correct:
when
$order: OrderType( $orderLineList: this.orderLine, priority != high )
$measureList: measure from $orderLineList
not ( this.measure < 12 ) from $measureList
then
modify( $order ){ setPriority( "high" ) }
end
The reason is that i'm implementing a rule editor for my work in a way that,
according to a selected xsd element from a displayed tree, i have to build
the right line of DRL code. So i m forced for many reason to use a form
similar to the one written above.
The pattern i'm using (and at this point i cannot change it anymore) is
something like this:
declaring $variableList
accessing the list using (this.property == value) FROM $variableList
it's a big costraint... i know... but i have to work this way.
So should the previous rule work?
Really thanks.

Re: [rules-users] Write Assumptions for NESTED List
if i have well understood the DRL code the solution, in a form more compliant
with my needs, could be something like this:
when
$order: OrderType( $orderLineList: this.orderLine, priority != high )
$measureList: measure from $orderLineList
not ( this.measure < 12 ) from $measureList
then
modify( $order ){ setPriority( "high" ) }
end
Is it right? i night to not use the get... methods... but directly to point
the variables (this.measure... this.orderLine ... i already tried this form
and it works).
Is it correct?

Re: [rules-users] Workitems doesn't get persisted when completing a task after rehydrating a knowledge session is some circumstances.
Hi Alberto, I'm not upset, kind the opposite. I'm sorry if my comments sounds harsh. I was making some assumptions based on my previous experience. My main point was, let's try to be concrete and let's work on code and failing tests. I know that is not trivial, but if we want to make the project better for everyone I think that's the only way to go. I'm keeping my mind open and I think that we all here are open to discussions, but lets discuss based on concrete proposals. If we don't go that way, this conversation will become cyclic and we will all loose time instead of being fixing bugs and adding new features :) On Tue, Jun 26, 2012 at 5:43 AM, Alberto R.

There's still some discrepancy between your Java and DRL code...
Using with the original limits, just redirect to quantity and measure,
respectively.
rule moreThanThree
when
$order : OrderType( priority != "high" )
not OrderLineType( quantity < 3 ) from $order.getOrderLines()
then
modify( $order ){ setPriority( "high" ) }
end
rule moreThanThreeTwelve
when
$order: OrderType( priority != "high" )
$olt: OrderLineType() from $order.getOrderLines()
not Measure( measure < 12 ) from $olt.getMeasures()
then
modify( $order ){ setPriority( "high" ) }
end

Re: [rules-users] Issues without response
@Edson: There is, of course, the fundamental problem of the pseudo-clock feature being full-bodiedly announced in Drools Fusion but SessionPseudoClock remaining absent from the stable API. While the Fusion manual emphasizes (correctly) that a pseudo-clock is useful in unit test it's important to note that there are good use cases for using it in certain production scenarios, both of which warrants that this feature should not be kept under-the-counter. -W On 26/06/2012, Edson Tirelli wrote: >Cyril, > >Thank you for reporting and providing a well written test case.

Re: [rules-users] Write Assumptions for NESTED List
The Java code as shown has a somewhat unlikely flavour, with
OrderLineMeasure containing the field List. And the
names used in the rules don't match the Java code, e.g.,
getUBLRuleEnginePriority().
And why should a String field quantity indicate the size of a List?
But see below for a (better) way of writing these rules.

Your rule would fire once for each OrderLine containing a quantity of
more than 2, which is quite another thing than an order with at least
3 order lines.
rule moreThanThree
when
$order : OrderType( orderLines.size() >= 3, priority != "high" )
then
modify( $order ){ setPriority( "high" ) }
end
You can access orderLines.size() without the need for "from". Testing
priority != "high" ensures that the rule does not loop if you use
modify to notify the Engine that something has changed (which you
probably should do).

rule moreThanThreeTwelve
when
$order: OrderType( orderLines.size() >= 3, priority != "high" )
not OrderLineType( measures.size() < 12 ) from $order.getOrderLines()
then
System.out.println( "3/12" );
modify( $order ){ setPriority( "high" ) }
end
Here "from" is required to extract the OrderLineType objects. The
"not" checks that they all have a List with at least 12 elements.

Re: [rules-users] Workitems doesn't get persisted when completing a task after rehydrating a knowledge session is some circumstances.
Mauricio, seems to me that you're upset. I'm really sorry, I didn't mean it. I didn't mean this thread to become a fud or some kind of rant.

You're making uninformed assumptions about our experiences with JBPM & Drools, both isolated and mixed, and our expectatives for the migration of our system from JBPM v3 to v5. We obviously were expecting some changes and some bugs. We were definetly not expecting such, IMHO, hard issues with the execution of long-running processes when persistence configured just because how the approach for mixing Drools & JBPM solution for persistence was done. This makes the system not fault tolerant, at least not without some pain and I agree in certain ( but not rare ) configurations. > > I've also notice that this is a step-by-step learning process, once you > master BPMN2 and how process works inside the process engine you can move > to Rules and then to Events, learning in the middle the technical and > logical requirements of each of them. > > > Most of the time the "solution" is understanding how the components > interact and can be mixed.

We believe in open source, that's why we chose Drools & JBPM in favor of other privative solutions. Hey!, At least here we have the chance to hack the code for dirty tricks! ;-). We also believe in an open and honest discussion of issues like this in this kind of projects. As you may know making a test case that reflects the situation mentioned in this thread takes time, is far from trivial, we really are in a hurry and deadlines are aproaching.

Hi Toni, It's very interesting to know it. It is possible that it is a bug. I did the test several times but the results are the same.
