Hi Zopistas - This is probably a really easy one, but I was wondering if anyone knows how to create an instance of one ZClass inside the constructor of a different ZClass. To illustrate with an example: I have defined two ZClasses, a ProjectManager and a GuestBook (I reimplemented the old Guestbook example product using ZClasses) as separate Products (since they are not really intrinsically related). I want to use the GuestBook in the ProjectManager, but I can't figure out how to create the GuestBook in the ProjectManager's constructor. I want to do something like <!--#call "GuestBook_add(id)"--> in the ProjectManager_add method; however, since the other Product's names don't seem to be defined in the namespace of ProjectManager_add, this doesn't work. Can anyone please tell me the magical solution to this problem? --Brian Hooper Digital Garage, Inc.
