All line separators in RHS in spreadsheet are escaped ----------------------------------------------------- Key: DROOLS-3805 URL: https://issues.jboss.org/browse/DROOLS-3805 Project: Drools Issue Type: Bug Components: decision tables Affects Versions: 7.18.0.Final, 7.19.0.Final Reporter: Toshiya Kobayashi Assignee: Mario Fusco Priority: Major Labels: support By DROOLS-3396, line separators in RHS are now escaped. https://github.com/kiegroup/drools/blob/7.18.0.Final/drools-decisiontable... However, it affects entire RHS so if you have multiple lines in ACTION, the result would be like this.
