thanks for your answers.

I first need to be sure I'm understanding the whole form framework, then I will 
surely try to implement something because I will increasingly need this kind of 
widgets. I also don't like to see components or widgets scattered into many 
packages, and it would be better to have most fonctionalities in a single 
framework. For instance, I'm wondering why z3c.formui is not z3c.form.ui (or 
z3c.form.template).

However the immediate thing I'll do now is just go to sleep :)
