[rules-users] For loop inside a modify block problem

[Martin A]

hi Michael,

All of the fields are public, however they are properties of a super class
of Item. I tried with getters, doesn't work either way.
Still getting: 'no such identifier : $item'. When I remove the for loop, it
goes ok, so I think it messes up things.

Best regards,
Martin
