[Zope3-Users] small bug in z3c.multiform package

[Lorenzo Gil Sanchez]

Hi,

I found a bug in FilterMapping class of the z3c.multiform package. 
Basically the problem is due to the way the __len__ method is computed.

Attached is a tiny patch for this bug. Feel free to use any copyright 
ownership you want for it.

Regards

Lorenzo
