Inside eval() you must use code in the chosen semantic dialect (either Java or MVEL). None of them have "not in" operator that is a DRL syntax sugar. So, you need to either properly write Java or MVEL code inside the eval, or use a regular DRL constraint.
In this specific case, if you are asserting the Map into the working memory, you can do something like: rule XXX when Map( this['name'] not in ("amit","siddhartha") ) then // do something end []s Edson 2007/9/11, Gaurav2007 <[EMAIL PROTECTED]>: > > > Hi All, > > I am using drool4.0.1 in my application, > > I have one map in global memory this map contains mapping of id and > value,i > want to validate these values. > > but when i am using in and not in rule like: > > eval(validatorMap.get("name") not in("amit","siddhartha")) > > where validatorMap is a map of id and value inserted in global memory. > > it is giving following error: > org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule > name=Short Name, agendaGroup=MAIN, salience=0, no-loop=false] > com/telekurs/nva/mde/fe/ak/validation/Rule_Short_Name_0.java > (8:330) : The > left-hand side of an assignment must be a variable > com/telekurs/nva/mde/fe/ak/validation/Rule_Short_Name_0.java > (8:357) : > Syntax error on token "not", invalid AssignmentOperator > > please help me how to validate value from a map using in and not in > operator > of drool. > > Thanks. > -- > View this message in context: > http://www.nabble.com/probliem-in-using--%22in%22-and-%22not-in%22-operator-in-drool-file.-tf4421498.html#a12611458 > 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
