Giorgio,

I respond here as I can attach files, i.e. they won't get mangled as 
they do on sourceforge.

If you create your own class for e.g. a Grid and you want to use it in 
the Boa designer you have to respect/use all the init arguments, you 
missed out "name".

Attached is a sample which runs.

Also note that I but the script encoding line in, this is important if 
you ever want to run this script on other machines and/or you want to 
use gettext to translate the app.

Werner
