Somehow I am unable to find a way to introduce more than a label in label expresison field of the job configuration. I tried any combination and it seems impossible to write something else than just a single label.

I don't know if that's just because I do not know the magic syntax but also the help text is completly missing to tell which kind of syntax you can put inside. In my case I wanted A && B kind of condition.

Even if that's only lack of knowledge this bug is still valid because the help-text does not contain any example.
