Edson Tirelli created DROOLS-2119: ------------------------------------- Summary: append() function does not support non-list first argument Key: DROOLS-2119 URL: https://issues.jboss.org/browse/DROOLS-2119 Project: Drools Issue Type: Bug Components: dmn engine Affects Versions: 7.4.1.Final Reporter: Edson Tirelli Assignee: Edson Tirelli Fix For: 7.5.0.Final The spec defines an axiom of [a]=a , i.e., singleton lists are equal to the single element and vice-versa. The current implementation for the append() function requires a list as the first element, but should accept a single element as well. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
