Hi, Further working with DSL (btw, we are using Drools 4.0.7), I found out that if there are two DSL statements such as: This is a "{node1}" This is a "{node1}" in "{tree}" Drools will throw some errors: Exception in thread "main" org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule name=aC, agendaGroup=MAIN, salience=0, no-loop=false] org/doxa/rules/deployer/Rule_aC_0.java (25:1671) : in cannot be resolved org/doxa/rules/deployer/Rule_aC_0.java (25:1674) : Syntax error on token ""tree3"", invalid AssignmentOperator at org.drools.rule.Package.checkValidity(Package.java:424) at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:394) at org.doxa.rules.deployer.RuleRunnerWithDSL.runRules(RuleRunnerWithDSL.java:36) at org.doxa.rules.deployer.RuleRunnerWithDSL.main(RuleRunnerWithDSL.java:118) Is this a bug? It took me almost 1 day to discover this. Hope this will provide other DSL users some light.

Thanks Olivier Sowmya -----Original Message----- From: rules-users-bounces(a)lists.jboss.org [mailto:rules-users-bounces@lists.jboss.org] On Behalf Of Olivier THIERRY Sent: Tuesday, December 16, 2008 1:59 PM To: Rules Users List Subject: Re: [rules-users] DSL: Problem of having 2 DSL statements that endsdifferently I had the same kind of problem : Drools stops on the first DSL sentence it can map to. If you want it to work, you have to be careful about the order you write sentences in your DSL : write them from the most restricitive to the less. In your case it should be : This is a "{node1}" in "{tree}" This is a "{node1}" Note Drools tools for Eclipse have nothing to change order, so you will have to open your DSL file as a text file to do this ;) Regards, Olivier 2008/12/16 cmgoh <cmgoh1979(a)gmail.com&gt;: > > Hi, > > Further working with DSL (btw, we are using Drools 4.0.7), I found out > that if there are two DSL statements such as: > > This is a "{node1}" > This is a "{node1}" in "{tree}" > > Drools will throw some errors: > Exception in thread "main" org.drools.rule.InvalidRulePackage: Rule > Compilation error : [Rule name=aC, agendaGroup=MAIN, salience=0, > no-loop=false] > org/doxa/rules/deployer/Rule_aC_0.java (25:1671) : in cannot be > resolved > org/doxa/rules/deployer/Rule_aC_0.java (25:1674) : Syntax error > on token ""tree3"", invalid AssignmentOperator > > at org.drools.rule.Package.checkValidity(Package.java:424) > at > org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:394) > at > org.doxa.rules.deployer.RuleRunnerWithDSL.runRules(RuleRunnerWithDSL.java:36) > at > org.doxa.rules.deployer.RuleRunnerWithDSL.main(RuleRunnerWithDSL.java: > 118) > > Is this a bug?
