Hi Peter,

I just checked in a fix for this problem into z3c.form and z3c.formui. It 
actually turned out that I had to fix2 bugs and add a feature to solve the 
problem. But it should be working now.

I did not make a new release yet, but will do that soon too.

Please let me know, if it is still not working!

Regards,
Stephan
