Guvnor/BRMS field named 'valid' breaks UI ----------------------------------------- Key: DROOLS-715 URL: https://issues.jboss.org/browse/DROOLS-715 Project: Drools Issue Type: Bug Reporter: Daniel Daniel Assignee: Mark Proctor I have a class called DrugDay, which has a boolean called valid. In my WHEN block, $drugDayA : DrugDay($uniqueIdA : uniqueId, $ctCodeA : ctCode, $dayA : day, valid == true) having the condition, "valid == true", breaks the UI, with no error in the logs. The guided rule has to be deleted, and created again. It is happy without the "valid == true" condition. Is this a reserved variable name?
