Drools date coercion and conditional OR --------------------------------------- Key: DROOLS-296 URL: https://issues.jboss.org/browse/DROOLS-296 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.5.0.Final Environment: Windows 7 Reporter: Madhura Jayaratne Assignee: Mario Fusco Fix For: 6.0.1.Final If I try a simple Drools rule with conditions on date type and uses conditional OR (||) I get the following error. If I change || to && it works fine. Condition $container: DateContainer( date >= "15-Oct-2013" || date <= "01-Oct-2013" ) Error Unable to Analyse Expression date >= "15-Oct-2013" || date <= "01-Oct-2013": [Error: Comparison operation requires compatible types. Found class java.util.Date and class java.lang.String] [Near : {... date >= "15-Oct-2013" || date <= "01-Oct-2013" ....}] ^ [Line: 9, Column: 1] : [Rule name='Test rule']
