Guvnor/BRMS Joda DateTime == operator breaking Guided Rule UI ------------------------------------------------------------- Key: DROOLS-716 URL: https://issues.jboss.org/browse/DROOLS-716 Project: Drools Issue Type: Bug Components: Guided Rule Editor Affects Versions: 6.2.0.CR4 Reporter: Daniel Daniel Assignee: Mark Proctor Priority: Major Labels: drools-tools I get the following error in the logs when I save: {noformat} 02:33:35,790 ERROR [org.kie.workbench.common.services.datamodel.backend.server.cache.LRUProjectDataModelOracleCache] (http-/0.0.0.0:8080-1) org.joda.time.format.ISODateTimeFormat and org.joda.time.format.ISODateTimeFormat$Constants disagree on InnerClasses attribute 02:33:35,829 ERROR [org.kie.workbench.common.services.datamodel.backend.server.cache.LRUProjectDataModelOracleCache] (http-/0.0.0.0:8080-1) org.joda.time.format.DateTimeFormatterBuilder and org.joda.time.format.DateTimeFormatterBuilder$TimeZoneId disagree on InnerClasses attribute {noformat} My breaking rule is {noformat} rule "Test DateTime" when $testDayA : TestDay($uniqueIdA : uniqueId, $dayA : day, valid == true) $testDayB : TestDay(uniqueId != $uniqueIdA, day == $dayA, valid == true) then $testDayA.setValid(false); update($testDayA); end {noformat} The day variable is {noformat} private DateTime day; {noformat} I can get the UI closing and opening if I remove 'day == $dayA'. That is the expression that breaks the UI.
