Re: [rules-users] collection question
Things would be smpler if you could avoid re-creating Product objects
because adding an identical Object does not change the Set. (This
could be implemented with the help of a global MapString,Product,)
Second, overriding equals (and hashCode) in Product would also avoid adding
an evil twin in your rule code - as it is!
Even simpler is a solution where the relevant Product objects are inserted
as facts, so that
$cd1 : Product( name == cd1 )
$bonus_cd : Product( name == bonus_cd )
$order : ShippingOrder( products contains $cd1, products not
contains $bonus_cd )
is true (again, with equals and hashCode being overridden).
Given your solution with collect, an additional eval testing for
bonus_cd not being the
name of the single Product in List $productList might be more
efficient than iterating
all products a second time.

I'm trying to write a rule to add an object to a collection if the collection
already contained a certain object with a specific attribute.
I developed a small example so maybe that will make more sense:
Use Case: In a product shipping applicaiton, anytime a product with the name
cd1 is in the shipping order, a bonus product named bonus_cd needs to be
added to the shipping order. The bonus cd should not be added if it's
already in the shipping order.
Shipping Order:
public class ShippingOrder {
private SetProduct products;
public ShippingOrder() {}
public SetProduct getProducts() {
return products;
}
public void setProducts(SetProduct products) {
this.products = products;
}
}
Product:
public class Product {
private String name;
public Product(){}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
Rule:
rule AddBonusCd
when
$so : ShippingOrder()
$productList : ArrayList(size == 1) from collect( Product(name
matches
cd1|bonus_cd) from $so.products)
then
System.out.println(Adding Bonus Cd);
SetProduct productSet = new
HashSetProduct($so.getProducts());
Product bonusCd = new Product();
bonusCd.setName(bonus_cd);
productSet.add(bonusCd);
modify($so) {
setProducts(productSet);
}
end
The Shipping Order object is inserted as the fact.
The rule is valid if only cd1 or cd_bonus is in the shipping order. I only
want the rule to run when cd1 is in the product set but cd_bonus is not.
Makes sense?
Thanks,
J

Re: [rules-users] Drools Planner or Drools Solver
The new docs will be published soon after the release of CR1 (including planner 5.1.0.CR1).

Re: [rules-users] Drools Flow - Human Task
How about simply reusing the human task node for this. Your process is then a simple sequence of 2 human task nodes. You can use the properties of the human task node (like name, description, content and input/output mapping to add the necessary information). Instead of using the default human task service for executing these tasks, you can then just write your own work item handler that notifies your UI when a task is created. Your UI should also notify the handler when a task is completed. Regarding continuing where you stopped last time, this happens automatically. When a work item is encountered, the process will halt until that work item has been completed. You should just keep your session alive, or if you use persistence you can simply restore the state from db as well.

Re: [rules-users] collection question
Hi J,
In your example I don't think that the collect is necessary.
I believe the following will work:
rule AddBonusCd
when
$so : ShippingOrder()
Product(name == cd1) from $so.products
not (Product(name == bonus_cd) from $so.products)
then
System.out.println(Adding Bonus Cd);
SetProduct productSet = new HashSetProduct($so.getProducts());
Product bonusCd = new Product();
bonusCd.setName(bonus_cd);
productSet.add(bonusCd);
modify($so) {
setProducts(productSet);
}
end
You don't need the collects because you are just checking for
existence/non-existence of facts within the products collection.
Good luck!
Steve

Given your solution with collect, an additional eval testing for

Re: [rules-users] Drools and mvel
Hi Paul, Your analysis is correct. The problem is that these configurations in MVEL are made using static properties and so they affect all uses of MVEL in a single classloading hierarchy. Unfortunately, I don't think there is anything you can do right now, other than open a JIRA in MVEL to help convince Mike to make all configurations non-static in MVEL: http://jira.codehaus.org/browse/MVEL Edson 2010/7/21 Paul Edwards paul.edwa...@hyro.com Hi guys, I have an issue which involves smooks, drools and mvel. Quick explanation, the unit test is just a smooks run. Nothing complicated. The test passes happily. It contains an expression that involves an MVEL IF statement. Now if I add a drools startup (I'm not using drools in the test, I'm just initialising it), the unit test now fails on the IF statement. The exception received is: org.milyn.cdr.SmooksConfigurationException: Error invoking @Initialize method 'initialize' on class 'org.milyn.javabean.BeanInstancePopulator'. at org.milyn.cdr.annotation.Configurator.invoke(Configurator.java:457) at org.milyn.cdr.annotation.Configurator.initialise(Configurator.java:439) at org.milyn.cdr.annotation.Configurator.configure(Configurator.java:91) at org.milyn.cdr.annotation.Configurator.configure(Configurator.java:66) at org.milyn.delivery.JavaContentHandlerFactory.create(JavaContentHandlerFactory.java:63) at org.milyn.delivery.ContentDeliveryConfigBuilder$ContentHandlerExtractionStrategy.addCDU(ContentDeliveryConfigBuilder.java:623) at org.milyn.delivery.ContentDeliveryConfigBuilder$ContentHandlerExtractionStrategy.applyCDUStrategy(ContentDeliveryConfigBuilder.java:548) at org.milyn.delivery.ContentDeliveryConfigBuilder$ContentHandlerExtractionStrategy.applyStrategy(ContentDeliveryConfigBuilder.java:536) at org.milyn.delivery.ContentDeliveryConfigBuilder$SmooksResourceConfigurationTableIterator.iterate(ContentDeliveryConfigBuilder.java:711) at org.milyn.delivery.ContentDeliveryConfigBuilder$SmooksResourceConfigurationTableIterator.access$300(ContentDeliveryConfigBuilder.java:690) at org.milyn.delivery.ContentDeliveryConfigBuilder.extractContentHandlers(ContentDeliveryConfigBuilder.java:484) at org.milyn.delivery.ContentDeliveryConfigBuilder.load(ContentDeliveryConfigBuilder.java:349) at org.milyn.delivery.ContentDeliveryConfigBuilder.getConfig(ContentDeliveryConfigBuilder.java:146) at org.milyn.container.standalone.StandaloneExecutionContext.init(StandaloneExecutionContext.java:91) at org.milyn.container.standalone.StandaloneExecutionContext.init(StandaloneExecutionContext.java:65) at org.milyn.Smooks.createExecutionContext(Smooks.java:383) at org.milyn.Smooks.createExecutionContext(Smooks.java:346) at com.hyro.telstrapoc.smooks.SmooksTransformTest.runSmooksTransform(SmooksTransformTest.java:215) at com.hyro.telstrapoc.smooks.SmooksTransformTest.testSmooks(SmooksTransformTest.java:139) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:73) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:46) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:180) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:41) at org.junit.runners.ParentRunner$1.evaluate(ParentRunner.java:173) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.internal.runners.statements.RunAfters.evaluate(RunAfters.java:31) at org.junit.runners.ParentRunner.run(ParentRunner.java:220) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at

Hi J,
In your example I don't think that the collect is necessary.
I believe the following will work:
rule AddBonusCd
when
$so : ShippingOrder()
Product(name == cd1) from $so.products
not (Product(name == bonus_cd) from $so.products)
then
System.out.println(Adding Bonus Cd);
SetProduct productSet = new HashSetProduct($so.getProducts());
Product bonusCd = new Product();
bonusCd.setName(bonus_cd);
productSet.add(bonusCd);
modify($so) {
setProducts(productSet);
}
end
You don't need the collects because you are just checking for
existence/non-existence of facts within the products collection.
Good luck!

Things would be smpler if you could avoid re-creating Product objects
because adding an identical Object does not change the Set. (This
could be implemented with the help of a global MapString,Product,)
Second, overriding equals (and hashCode) in Product would also avoid adding
an evil twin in your rule code - as it is!
Even simpler is a solution where the relevant Product objects are inserted
as facts, so that
$cd1 : Product( name == cd1 )
$bonus_cd : Product( name == bonus_cd )
$order : ShippingOrder( products contains $cd1, products not
contains $bonus_cd )
is true (again, with equals and hashCode being overridden).
Given your solution with collect, an additional eval testing for
bonus_cd not being the
name of the single Product in List $productList might be more
efficient than iterating
all products a second time.

Re: [rules-users] Timers' Week :)
I probably missed quite a few emails on the mailing list lately (sorry), but what's the exact problem with timers and persistence (and does it still exist in the latest trunk, as I know various improvements / bug fixes have been applied in the last few weeks as well)? There's a simple test that shows the use of timers and persistence together: testPersistenceTimer() in http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-persistence-jpa/src/test/java/org/drools/persistence/session/PersistentStatefulSessionTest.java If you are having issues, please let me know (and if possible provide a test case like the one above that shows this behaviour ;)) and I'll take a look.

I did test timer behavior when an exception is thrown from within the workItemHandler that has a timer attached to it. And in this case the timer keeps working, that is, it does not stop if you exit workItemHandler abnormally.

[rules-users] Rules not firing when expected after retracting object in list
Hi,
I'm coming across some weird behavior in Drools 4.0.7, but maybe it's just
cause I don't understand I how Drools works. Assume, there's a class A
that has a property called property.
As facts, I have the following list of A's:
A1, property = 123
A2, property = 345
A3, property = 123
I have two rules as follows:
rule Rule 1 - Remove all A's that have property set to 123
salience 1000
lock-on-active true
when
$listOfAs : ArrayList collect(A( property == 123 ))
then
for (Object a: $listOfAs ) {
retract (a)
}
end
rule Rule 2 - Do stuff with remaining A's
salience 900
lock-on-active true
when
$listOfAs : ArrayList collect(A())
then
...
end
My understanding is Rule 1 will remove the facts of class A that have
property to 123. When it gets to Rule 2, shouldn't the listOfAs only
have that one A that remains (i.e. the one where property is set to 345).
What I'm noticing is that Rule 2 just doesn't execute at all even though
I'm assuming there is still one A object that hasn't been retracted. If I
comment out the retract it executes Rule 2 fine.
Am I missing something about these rules work?
Thanks.

What if you have multiple A's set with 123? Don't you need to collect them
to retract all A's that match that property?
My main concern is if you retract one or more of the A's, it's possible that
you should still have some A's that are NOT retracted, so rule B should
still fire right?

If you did only want the rule to run once regardless of how many matching As

Hi Mark,
I assume you are referring to: drools.dialect.mvel.strict =true|false as I
cannot see any other config items. I have already tried setting that to false
(I should have put that in the first email) but it didn't work.
I'm guessing that leaves me needing to raise a Jira issue???

It is possible to turn off the language constraint for MVEL in drools, see
KnowledgeBuilderConfiguration, which should cause the static field not to be
set.

Hi Paul,
Your analysis is correct. The problem is that these configurations in
MVEL are made using static properties and so they affect all uses of MVEL in
a single classloading hierarchy. Unfortunately, I don't think there is
anything you can do right now, other than open a JIRA in MVEL to help
convince Mike to make all configurations non-static in MVEL:

Hi guys,
I have an issue which involves smooks, drools and mvel.
Quick explanation, the unit test is just a smooks run. Nothing complicated.
The test passes happily. It contains an expression that involves an MVEL IF
statement.
Now if I add a drools startup (I'm not using drools in the test, I'm just
initialising it), the unit test now fails on the IF statement. The
exception received is:
org.milyn.cdr.SmooksConfigurationException: Error invoking @Initialize method
'initialize' on class 'org.milyn.javabean.BeanInstancePopulator'.
