[jboss-jira] [JBoss JIRA] Updated: (JBRULES-1440) Support for Nested Templates

[ http://jira.jboss.com/jira/browse/JBRULES-1440?page=all ] greywind updated JBRULES-1440: ------------------------------ Attachment: current.drl This is what is currently possible. The 'nested' Facts have type Object. due to that I cannot access the Properties directly but have to use the from clause. If I do try to access it directly I do get an ArrayIndexOutOfBoundsException in mvel and an (org.drools.RuntimeDroolsException: This is a bug.
