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

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.
