Re: [rules-users] priority based on object properties
A rule's salience can be defined with an arbitrary expression which may include variables bound to mathced fact fields. It should be possible to compute the effective salience from a base salience (according to the rule) plus an offset value derived from field values. -W On 18 July 2011 21:44, Simon Chen simonche...@gmail.com wrote: Hi all, I am curious if we can inform Drools' execution based on properties within objects.

To give an example, I am (still) playing with implementing shortest path using a few rules. I have a rule for selecting a shortest path on a node (among all the paths received from its neighbors) to a source node, and another rule for propagating the shortest path on a node to neighboring nodes. When I have many nodes in my graph, I found that the paths propagated (via the second rule) are not always the shortest, while Dijkstra's algorithm always propagate from the node with the shortest distance to the source. The effect is that my rules are wasting most of the time propagating paths that would be dropped in the end anyway... Any ideas?

Hi Mike,

Thank You for your responses.

My apologies.

I did miss copying the closing bracket.the issue still exists though . I
suspect whether the way the code has been generated by jaxb has anything to
do with it.

In the xml, the field is all upper case as

Hello ,
I am using 5.2.0.CR1 version of Guvnor .
I have a jaxb generated class loaded through the model jar into Guvnor to
be used as a fact in the Guided Decision Table editor.
When I use a field ACTIVITYCODE of type String from the JAXB generated
class with ‘ is contained in the comma separated list' operator, I get
compilation errors.
Unable to Analyse Expression ACTIVITYCODE == A || ACTIVITYCODE == B:
[Error: no such identifier: ACTIVITYCODE] [Near : {... ACTIVITYCODE == A

But when I use equal to operator to compare value to just a string value,
it compiles fine.
This rule fails.

Is this issue being caused by jaxb generated class? If so, is there a way
to fix this problem?
When I use a regular pojo that is not jaxb generated, the
is contained in the comma separated list' operator works fine.
Can someone provide any direction or thoughts on this?

AFAIK, there never was any logic for restricting updates of the Rete structures according to individual field-oriented change notifications. As far I remember, JRules does. And it could be great to add/restore this possibility in drools (is there a JIRA somewhere where we can vote?).

Re: [rules-users] priority based on object properties
Wolfgang, How does the offset thing work exactly? Do we set one salience value for a rule and another offset value based on the fact fields? Or do we have one expression for salience, in the form of X+Y, where X is a static numeric value and Y is a formula based on the facts? It seems to me that the latter case is not much different, because all activations must be sorted based on the derived salience. The former case might be useful, as Drools can potentially first roughly sort the activations based on salience values, and then sort the smaller subsets of activations based on their offset values. Thanks. -Simon 2011/7/19 Wolfgang Laun wolfgang.l...@gmail.com: A rule's salience can be defined with an arbitrary expression which may include variables bound to mathced fact fields.

[rules-users] [Drools4]: Filter executed rules by *.drl file
Before I start do explain my problem I should say that I have already
searched through the older posts and found similiar problems but not exactly
the following one:
My Application has multiple RuleFiles (*.drl each with its own package)
which can be dynamically added/removed. Based on a context (lets say String
foo = bar) only the rulepackage which fits to bar should be executed.
Usually that isnt a problem, because drools just executes the rules with the
fitting facts. But in this case all the rules in the rulepackages check the
same type of facts.
Currently I am using an AgendaFilter (if rulepackage == xyz { accept =
true}) to achieve this goal, but firstly it doesnt effect inserting of facts
(LHS of every rule is executed) and secondly I have read that it should only
be used for unit testing, since it couples java code with rule behavior.
While reading older posts I have found two possible solutions that could
work:
1. Using a contextObject which has foo and is checked in the first rule of
each rulepackage. This first rule and the remaining rules in the rulepackage
have the same agenda group. So if the first rule doesnt fit, the other rules
wont be executed, either (does this really work? ;)).
2. Putting every rulepackge in its own rulebase. Then I would check the
context in java and execute the fitting rulebase.
Let's say I have about 300 *.drl files. Which solution would be better?
Maybe there is a better solution 3) of which I didnt think yet. Then dont
hesitate and tell it to me :)
Thanks in advance for any help.

Re: [rules-users] [Drools4]: Filter executed rules by *.drl file
In your scenario, I believe the best (better) approach would be to use a control fact (first in your RHS). Your context can become a Fact itself:- rule one when Foo( value == bar ) ...other patterns then ...do your thang end rule two when Foo( value == bar ) ...other patterns then ...do your other thang end On 19 July 2011 16:25, magendo robert.heisenb...@yahoo.com wrote: magendo wrote: 1.

Re: [rules-users] [Drools4]: Filter executed rules by *.drl file
In my opinion, for 300 drl files, the better is to use a specific KB for each DRL (or some KAgent). This way you don't have to pollute your rules with control facts (and you can eventually re-use some part of DRL files into multiple context KB), and the RETE is tightened to the strict minimum (no eval of useless constraints). Moreover, I am not sure if drools compiler can really handle some removal or addition of rules dynamically in a existing KB without having to recompile all rules (so keeping up-to-date a big KB can be costly). If you (still) want to use your solution 1 (ie control facts), you can also use rule inheritance (which make a rule inherit the conditions of another parent rule, and the parent rule will contain the check on the control fact) : rule context-rule enabled false // this rule won't fire by itself when Context(task = bar) then // not used anyway end rule X extends context-rule when // specific conditions then // fired when specific conditions AND context-rule's conditions are met end ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] concurrent modification of a rule by more than one user in Guvnor
Hi Mike, We tried this out by testing with 2 users logging into Guvnor and changing rules. When the 2 users opened the same rule one after the other, the second user did not get any warning . the first user was able to save his changes successfully, but the second user got an error indicting that the asset is out of Date and lost his changes . We did confirm that users get similar error when they work on different rows of the same decision table .That is apparently because the lock is at the asset level and not at row level as has been stated in your email. No warning seen even for decision Table when second user tried to open the same Table.

[rules-users] Unexpected variable binding behavior and conditional logic
Apologies if this has been addressed elsewhere: I couldn't find anything
quite like my issue.
My (greatly simplified and completely made-up) example:
Let's say I have this java class:
public class BaseballPitcher
{
public String getName();
public boolean isRightHanded();
public boolean isKnuckleBaller();
}
Multiple instances of this class are created with a variety of combinations
for the name and two boolean parameters.
Now I have a rule:
rule Match pitchers: righties or knuckle-ballers
when
$kbPitcher1 : BaseballPitcher($name: name, $righty: rightHanded == true
||
$knuckleballer: knuckleBaller == true)
$kbPitcher2: BaseballPitcher(name != $name, rightHanded == $righty,
knuckleBaller == $knuckleballer)
then
// Do something with these two pitchers $kbPitcher1 and $kbPitcher2
end
I am getting the curious result that this rule fires its conclusion when
$kbPitcher1 is in fact NEITHER right-handed nor a knuckle-baller (i.e.
rightHanded == false knuckleBaller == false).
I've worked around this by changing the first condition in either of the
following two ways:
*// eval() the condition*
$kbPitcher1 : BaseballPitcher($name: name, $righty: rightHanded,
$knuckleballer: knuckleBaller,
*eval(isRightHanded() == true || isKnuckleBaller() == true)*)
...or
*// bind the variables before checking values*
$kbPitcher1 : BaseballPitcher($name: name, $righty: rightHanded,
$knuckleballer: knuckleBaller,
*rightHanded == true || knuckleBaller == true*)
Does this make sense? Both are easy workarounds, and I believe the second
option (i.e. the one NOT using the eval) is the better solution from a
performance perspective, allowing the engine to index the these facts rather
than dynamically evaluate the condition every time.
But I'm a little surprised the first approach didn't work. Any ideas why
not?
