[rules-users] depicting array in rules

[Esteban Aliverti]

One way could be:

*
*

*when*



      Fire($room : room)

      $sprinkler : Sprinkler(room contains $room)

      Room (this == $room, someField == "SomeValue")

      *then*

            *modify*($sprinkler){

                  setStatus(true)

                  };

End

If you dont have the Room as a Fact Type, then:

*when*



      Fire($room : room)

      $sprinkler : Sprinkler(room contains $room)

      Room (someField == "SomeValue")from $room

      *then*

            *modify*($sprinkler){

                  setStatus(true)

                  };

End


I'm not 100% sure about this, but at least you can start from here
