not() unary test is short circuiting in the presence of null ------------------------------------------------------------ Key: DROOLS-1465 URL: https://issues.jboss.org/browse/DROOLS-1465 Project: Drools Issue Type: Bug Components: dmn engine Affects Versions: 7.0.0.Beta6 Reporter: Edson Tirelli Assignee: Edson Tirelli Fix For: 7.0.0.Final Grammar rule #17 prevents not() from being used as part of a unary test list. Needs to be fixed in the engine. Also, there seems to be a bug on the creation of not() unary tests as it is short-circuiting in some cases without checking all the elements.
