Add tests to confirm that singleton lists can be treated as the element itself in filter results ------------------------------------------------------------------------------------------------ Key: DROOLS-1547 URL: https://issues.jboss.org/browse/DROOLS-1547 Project: Drools Issue Type: Task Components: dmn engine Affects Versions: 7.0.0.CR3 Reporter: Edson Tirelli Assignee: Edson Tirelli Fix For: 7.1.0.Final The specification has a provision that singleton lists should be treated as the element itself in some cases, like filter results. I.e., in some cases, {{[a] = a}}. This is not completely consistent, but we need to handle it for some cases, like filter results. In other words, the following assignment should work fine, assuming {{a flight}} is a flight variable and {{flight list}} is a list of flights, and the filter returns a single result. {code} { a flight : flight list[ number = "AC 531" ] } {code} We need to add tests to make sure it is working like that and fix it in case it is not.
