[rules-users] Using java.util.List in rules

[Anderson Pazza Mello]

How can I test all elements of the list?
Can I need to use something like "for (int i.....)"?

I'm trying to do that but it is not working...

"Caracteristica( codCarac != 0 ) from $caracList"



My test:

        e : Especialista (perguntado == false)
        Especialista( $moldeList : retratoUser.lstMolde )
        Molde( tipoMolde == TipoMolde.CABELO) from $moldeList


When  the property  "tipoMolde == TipoMolde.CABELO" the rule must to be
fired. The List $moldeList has 5 elements.

any idea?
