Nah thats not gonna work, because I'm using an ArrayList as a global variable. I'm adding and removing ODMAnswers in it and always want to check if there are 2 ODMAnswers in it, to remove them and generate a new one.
Of course I differ them in their properties, just wanted to keep the problem simple and understandable. Do you got another option than creating a local $list variable? ----- Ursprüngliche Mail ----- Von: "Jeremy Ary" <[email protected]> An: "Rules Users List" <[email protected]> Gesendet: Mittwoch, 16.
