"$r.installations" only works if the attribute is public in RuleObject (and numeric). try $r.getInstallations() instead ...
Also, always have a look to the generated DRL ("View Source" under Guvnor) ----- Mail original ----- De: "Manasi" <manasi.a.da...@capgemini.com> À: rules-users@lists.jboss.org Envoyé: Vendredi 11 Mai 2012 12:34:02 Objet: [rules-users] Formula error in Business Rule(Guided editor) Hi, Currently I am facing following issue while inserting a formula in Business Rule(Guided Editor): 1) I have written following formula to be executed in Business Rule(Guided Editor): WHEN 1. The following exists: There is a RuleObject [$r] with: installations < 100 THEN 1. Insert RuleObject: calulatedValue = $r.installations*3 But it gives error 'Unable to analyse expression' when i try to Verify the rule. I want my end result will be a calculated value instead of Literal value. Please let me know the correct syntax to use formula in this type of rule. Thnaks. -- View this message in context: http://drools.46999.n3.nabble.com/Formula-error-in-Business-Rule-Guided-editor-tp3979546.html Sent from the Drools: User forum 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 mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
