Re: [rules-users] Accum question
Thanks Edson. Yea, I typed it on the fly instead of cut/paste. I will try the inline eval. Your help is appreciated! Edson Tirelli-3 wrote: Sorry, it is not clear what you are trying to do. There are a few clear mistakes in your rule: 1. You can't use the $totV variable inside the accumulate, since $totV is the result of the accumulate. 2. You can't use variables bound inside accumulate outside of it, since accumulate is a scope delimiter ($ciNo, $ciLineNo). 3. If you want to sum values, use sum() function, but if you want to count occurrences, use the count() function. 4. This expression is wrong: $totV 1. You must either compare something to a field or use an eval() (inlined or not) to evaluate arbitrary expressions. 5. I think it is simply a typo, but since the DRL is case sensitive, the java class Number must be written with capital N. Maybe if you can explain with more common terms what rule you are trying to write, we can help more... the best I could imagine is: rule 00910 Pass XV sets when $status : ValidationPassFailStatus() exists ValidationControl(validationNo == 910) CiLines( $ciNo : $ciNo, $ciLineNo : $ciLineNo, spiSecondary == X ) Number( intValue 1 ) from accumulate( $c : CiLines( ciNo == $ciNo, ciLineNo == $ciLineNo, spiSecondary == V ), count( $c ) ) then $status.pass(910); end Hope it helps. Edson 2007/7/27, Mike D [EMAIL PROTECTED]: Newbie question again... I'm trying to get a count of V lines if I have an X. If more than 1 V line, I pass... Obviously I can't have $totV on LHS, but you get my drift. What is the correct syntax for this one? I've been digging in the docs on accum, but can't find anything that fits what I'm trying to do. Thanks, Mike rule 00910 Pass XV sets when $status : ValidationPassFailStatus() exists ValidationControl(validationNo == 910) $totV : number() from accumulate(CiLines($ciNo : $ciNo, $ciLineNo : ciLineNo, spiSecondary == V), sum($totV)) CiLines(ciNo == $ciNo, ciLineNo == $ciLineNo, spiSecondary == X, $totV 1) then $status.pass(910); end -- View this message in context: http://www.nabble.com/Accum-question-tf4157809.html#a11829193 Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli Software Engineer - JBoss Rules Core Developer Office: +55 11 3529-6000 Mobile: +55 11 9287-5646 JBoss, a division of Red Hat @ www.jboss.com ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- View this message in context: http://www.nabble.com/Accum-question-tf4157809.html#a11830313 Sent from the drools - user 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] adding process to an empty rule base
Is it possible to set the rule flow in my rule base before adding rule packages : ruleBase = RuleBaseFactory.newRuleBase(); org.drools.compiler.ProcessBuilder processBuilder = new ProcessBuilder(new PackageBuilder()); processBuilder.addProcessFromFile(ruleFlow); ruleBase.addProcess(processBuilder.getProcesses()[0]); thanks -- View this message in context: http://www.nabble.com/adding-process-to-an-empty-rule-base-tf4157978.html#a11829714 Sent from the drools - user 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] adding process to an empty rule base
This error is caused by a mismatch between the version of the mvel library you are using and the version that is expected by drools. Drools 4.0.0 is expecting mvel14-1.2rc1.jar. Previous versions of drools are probably based on older versions of mvel. Might also be caused by having multiple versions of mvel in your classpath.

Re: [rules-users] adding process to an empty rule base
If I do like this, it works : PackageBuilder builder = new PackageBuilder(); Reader drlReader = new InputStreamReader(getClass().getResourceAsStream(/emptyPackage.drl)); builder.addPackageFromDrl(drlReader); builder.addRuleFlow(ruleFlow); Package pkgRuleFlow = builder.getPackage(); ruleBase.addPackage(pkgRuleFlow); In the emptyPackage.drl file this no rules, but it seems to be impossible to have a rule base with only a rule flow.
