I am having a problem with eval() which can be found here: http://rafb.net/p/GnneUd12.html. Sorry for not posting the question here but I kept getting a top-posting error. If anyone knows why I would get the top-posting error I would love to know why. Thanks in advance, Brian Enderle _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

> Best way to know is preview your DRL rule in IDE and check what is wrong (or paste it here). []s Edson Here is the working rule: rule "LevelTwo: MEPS Processing cannot be blank if Projection exists" agenda-group "LevelTwo" when > $i : MepsProcessing(eval(mepsProjTypCd != null) && eval (mepsProjTypCd != ' '), eval(StringUtils.isBlank(mepsId))) then > System.out.println("Meps Id cannot be blank"); end When I replace the two conditions with a DSL entry, the rule works with the DSL conditions individually as in: There is a MepsProcessing - mepsProjTypCd is not a blank Character or There is a MepsProcessing - mepsId is a blank String But as soon as I put the two conditions together I get the error. rule "LevelTwo: MEPS Processing cannot be blank if Projection exists" agenda-group "LevelTwo" when There is a MepsProcessing - mepsProjTypCd is not a blank Character - mepsId is a blank String then > System.out.println("Meps Id cannot be blank"); end Error: Caused by: org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule name=LevelTwo: MEPS Processing cannot be blank if Projection exists, agendaGroup=LevelTwo, salience=0, no-loop=false] mil/army/usaac/ariss/dca/bp/Rule_LevelTwo__MEPS_Processing_cannot_be_bl ank_if_Projection_exists_0.java (33:1686) : Syntax error on token ",", . expected mil/army/usaac/ariss/dca/bp/Rule_LevelTwo__MEPS_Processing_cannot_be_bl ank_if_Projection_exists_0.java (33:1713) : mepsId cannot be resolved Any ideas, Brian Enderle > https://lists.jboss.org/mailman/listinfo/rules-users > _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Yes, but what is the preview of your DSL rule in DRL form? There is a tab
