[ https://issues.jboss.org/browse/JBRULES-3336?page=com.atlassian.jira.plug... ] Miles Wen updated JBRULES-3336: ------------------------------- Description: This code could not be parsed correctly: rule "out" when Msg(!(set not contains "test")) then end I tried a few simple situations and found that when using 'not contains' operator in a '\!' leading parentheses triggers this problem. If no '\!' prefixing the parentheses,the program works like a charm... The example above seemed so stupid(you can use a 'contains' operator instead), but this is the simplest toy example.And this problem would be looked more important if you want to write some logic like this: Msg(!(set not contains "test" || !bool && string == "hello")) was: This code could not be parsed correctly: rule "out" when Msg(!(set not contains "test")) then end I tried a few simple situations and found that when using 'not contains' operator in a \'!\' leading parentheses triggers this problem.
