Re: [rules-users] LHS Dao Calls

Thanks Edson .. i tried with these syntaxes but does not work .. any other clues ? just to let you know that itemValidationDao is declared global and itemvo is asserted *when* *item : ItemVo(itemStatusCode != ItemVo.STATUS_ACTIVE , ( itemValidationDao.isValidItemStatus(itemStatusCode)))* Caused by: org.drools.rule.InvalidRulePackage: unknown:15:70 Unexpected token '(' unknown:16:1 mismatched token: [@160,673:676='then',<33>,16:1]; expecting type ')' unknown:17:29 Unexpected token '"itemStatusCode"' unknown:18:22 Unexpected token '"Item is cross ref prime"' *when* *item : ItemVo(statusCode : itemStatusCode != ItemVo.STATUS_ACTIVE , itemValidationDao.isValidItemStatus(statusCode))* Caused by: org.drools.rule.InvalidRulePackage: unknown:15:70 Unexpected token 'itemValidationDao' unknown:16:1 mismatched token: [@158,671:674='then',<33>,16:1]; expecting type ')' unknown:17:29 Unexpected token '"itemStatusCode"' unknown:18:22 Unexpected token '"Item is cross ref prime"' This also does not seem to work -- i have 3.1.0 M1 version .. item : ItemVo ( itemStatusCode == ItemVo.STATUS_ACTIVE | == ItemVo.STATUS_DELETE ) while this still works : item : ItemVo(itemStatusCode == ItemVo.STATUS_INACTIVE) or ItemVo(itemStatusCode == ItemVo.STATUS_DELETE) ------------------------------ *From:* rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] *On Behalf Of *Edson Tirelli *Sent:* Friday, April 06, 2007 10:22 AM *To:* Rules Users List *Subject:* Re: [rules-users] LHS Dao Calls Sunjay, Methods called by using the "from" CE are expected to return a collection of VO's, not boolean results. For your case, probably what you want is something like: ItemVo( statusCode : itemStatusCode != null, (* itemValidationDao.isValidItemStatus(statusCode)*) ) A predicate allow you to call a method returning a boolean value and use it as a constraint.
