Issues like that led me to z3c.form, which implements subforms that can be 
used to do things like that and much more.

Although it's complicated - and I tell you - it's really complicated - it's 
absolutely worth it. If you are interested, I recommend to have a look at 
z3c.formdemo which points out several applications.

Best Regards,
