>             Project: Drools
>          Issue Type: Feature Request
>    Affects Versions: 5.5.0.Final, 6.0.1.Final

> When processing a query CE that uses chained property accessors:
> when
>   $x : Foo()
>   myQuery( $x.bar ; ) 
> then
> the QueryElementBuilder considers the whole expression $x.bar as a variable. Since no variable with that name has been bound, it is taken to be a new declaration, and thus an output. This results in an inconsistent behavior, since an obvious constraint will be ignored.
