Re: [rules-users] Bugs in rule templates?

** Hi Wolfgang, Sure. Please find attached a small Maven/Eclipse project containing 3 DRT and 3 unit test cases (Java in src/test/java/org/drools/bug, rules in src/test/resource/org/drools/bug) : - Test1OK(.java/.drt/.csv) is the one working well - Test1KO(.java/.drt/.csv) is the one illustrating the 1) behavior - Test1KO2(.java/.drt/.csv) is the one illustrating the 2) behavior Regards, Bruno.
