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

You could try assigning $item to a local variable and then using that within the for loop?**** ** ** Thomas**** ** ** *From:* rules-users-bounces(a)lists.jboss.org [mailto: rules-users-bounces(a)lists.jboss.org] *On Behalf Of *Martin A *Sent:* 11 January 2012 10:02 *To:* Rules Users List *Subject:* 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.
