>             Project: Drools
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: drools-compiler (expert)
>    Affects Versions: 5.3.0.Final
>         Environment: jdk 1.6u27 drools 5.3.0 final
>            Reporter: Miles Wen

>              Labels: notcontains, parentheses

> 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"))
