Re: [rules-users] Date for 2 years ago
Hello Brian, I've done something similar previously using a combination of a field binding constraint, an eval and the excellent joda-time API (http://joda-time.sourceforge.net/). If I remember right, you'd need something along the lines of : import org.joda.time.Duration; import org.joda.time.DateTime; Reference($fromDate : fromDate, eval(new Duration(new DateTime($fromDate), new DateTime()).getMillis() (2*365*24*60*60*1000))) It might be more readable if you can encapsulate this in a function :-) Dean.

Re: [rules-users] Problem in using or operator with values in map.
This seems a bug. May I ask you please to open a JIRA for it and attach a self contained test showing the problem? At the same time, I think there is a conceptual error in your rules: no object should be changed in the LHS of the rules. This will surely cause you problems in the future, so, I strongly advise you to rethink your rules.

Re: [rules-users] Problem with memberOf and/or eval used in collect statement
Chris, Thanks for reporting this. I fixed a bug in 4.0.0 (released in 4.0.1) that causes you to see the correct value for TestEval1 in 4.0.1 and later versions. Although, at that time I missed the memberOf scenario. I know why it happens (shadow fact related), but now I need to figure out a way to fix it. May I ask you to open a ticket for that?

My test includes 3 rules each written to output the same results (I think), but I get different results (depending on which version of Drools I use).

Re: [rules-users] how to perform some task when rule fails.
Hi, First, it would be better if you can use the constraints inside the same pattern, avoiding subrule generation, instead of using multiple patterns: Map( this[G250.18] !=4 this[G250.4] not in(910,990,983,995, 996,997) || this[G250.18] ==4 this[G250.4] in (910,990,983,995,996,997) ) Remember that has precedence over ||, but you can use () if you want to make it explicit: Map( ( this[G250.18] !=4 this[G250.4] not in(910,990,983,995, 996,997) ) || ( this[G250.18] ==4 this[G250.4] in (910,990,983,995,996,997) ) ) Now, answering your question, if you want to negate part of the whole of the LHS, just use the not CE. Example: rule ValidationRuleExp_G250.4_0 when not ( IValidationField(attributeId ==G250.4) and Map( this[G250.18] !=4 this[G250.4] not in(910,990,983,995, 996,997) || this[G250.18] ==4 this[G250.4] in (910,990,983,995,996,997) ) ) then // do something end Hope it helps, Edson 2007/9/18, Gaurav2007 [EMAIL PROTECTED]: Hi All, My requirment is that i want to send corresponding error when any rule fails. for example: rule ValidationRuleExp_G250.4_0 when IValidationField(attributeId ==G250.4) (((Map( this[G250.18] !=4))(Map( this[G250.4]not in(910,990,983,995,996,997||((Map( this[G250.18] ==4))(Map( this[G250.4] in(910,990,983,995,996,997) then System.out.println(comming here---Success--); end In this case i can call some method in success,Is there any way so that i can call some method when any rule fails. the problem is that i am trying to generate rule file and all the validation expressions are already defined. my task is to evaluate these expression and generate corresponding error message when any rule fails can you please suggest me how can i do this using drools.

Re: [rules-users] Exception executing predicate
Krushnan,
Isn't there a cause by down the stack trace? Current code for raising
the exception is:
try {
return this.expression.evaluate( object,
null,
this.previousDeclarations,
this.localDeclarations,
workingMemory );
} catch ( final Exception e ) {
throw new RuntimeDroolsException( Exception executing predicate
+ this.expression,
e );
}
All we can say for sure from the exception stack trace snippet you
provided is that it was raised in a rule named Rule Cisco Systems, in the
first return value predicate.
We need to improve that a bit I think.

Re: [rules-users] Problem with memberOf and/or eval used in collect statement
Chris, Do you really need to collect all these facts? Are you doing anything with these lists? It would be easier if you can show me the full rule, but seems to me that maybe you can avoid some or all of these collects. Remember that collect is a heavy CE, so it is always good to avoid when possible. Anyway, there should be no problem if you use eval(). The problem in JBRULES-1204 only affects memberOf operator, since the fix I implemented in http://jira.jboss.org/jira/browse/JBRULES-1115 fixed the eval()s. I will fix 1204 asap.

I fixed a bug in 4.0.0 (released in 4.0.1) that causes you to see the correct value for TestEval1 in 4.0.1 and later versions. Although, at that time I missed the memberOf scenario. I know why it happens (shadow fact related), but now I need to figure out a way to fix it. May I ask you to open a ticket for that? Thanks, Edson 2007/9/18, Chris West [EMAIL PROTECTED]: All, I'm having a problem using memberOf combined with a collect statement. My test includes 3 rules each written to output the same results (I think), but I get different results (depending on which version of Drools I use). The rules are: rule TestMemberOf salience 10 when $messages: ArrayList() from collect (Message(status == 100)) $wrappers: ArrayList() from collect (Wrapper(message memberOf $messages)) then System.out.println(TestMemberOf: + $wrappers.size()); end rule TestEval1 salience 9 when $messages: ArrayList() from collect (Message(status == 100)) $wrappers: ArrayList() from collect (Wrapper($message: message, eval($messages.contains($message then System.out.println(TestEval1: + $wrappers.size()); end rule TestEval2 salience 8 when $wrappers: ArrayList() from collect (Wrapper($message: message, eval($message.getStatus() == 100))) then System.out.println(TestEval2: + $wrappers.size()); end The output is (by version): 4.0.0 TestMemberOf: 0 TestEval1: 0 TestEval2: 2 4.0.1 TestMemberOf: 0 TestEval1: 2 TestEval2: 2 4.0.2.SNAPSHOT (taken 9/18/07) TestMemberOf: 0 TestEval1: 2 TestEval2: 2 The correct output should be: TestMemberOf: 2 TestEval1: 2 TestEval2: 2 Am I using memberOf correctly? Is there some issue using an eval to test conditions on a list created by a collect? Any help would be appreciated. Attached is the full example.

Re: [rules-users] Problem with memberOf and/or eval used in collect statement
The fix for 1115 and fix for 1204 you're working will not help me unless 1203 is fixed, because all versions of code after 4.0.0 are affected by 1203, and it is a showstopper for me since I use JDK dynamic proxies as facts. -Chris On 9/18/07, Edson Tirelli [EMAIL PROTECTED] wrote: Chris, Do you really need to collect all these facts?
