[Guided Rule] Can't be opened if constraint to bound field present ------------------------------------------------------------------ Key: DROOLS-2781 URL: https://issues.jboss.org/browse/DROOLS-2781 Project: Drools Issue Type: Bug Components: Guided Rule Editor Affects Versions: 7.9.0.Final Reporter: Jozef Marko Assignee: Toni Rikkola Priority: Critical Labels: drools-tools Attachments: Screenshot from 2018-07-24 14-32-00.png {code:mvel} package com.myspace.repr; import java.lang.Number; rule "rule" dialect "mvel" when DataObject( $stringField : sFieldOne == "something" ) DataObjectTwo( sFieldTwo == $stringField ) then end {code} Assume the rdrl file above where both *sFieldOne* and *sFieldTwo* are both of *String* type. Then if you try open this rdrl file in workbench the unexpected error dialog appears. The same can be seen if we assign role EVENT to *DataObject* and have this rule below. {code:mvel} package com.myspace.repr; import java.lang.Number; rule "eventRule" dialect "mvel" when e1 : DataObject( this after [1m, 2m] "24-Jul-2018" ) over window:time (10d) e2 : DataObject( this before e1 ) then end {code}
