[html-formfu] 'default_empty_value' doesn't work

[Juergen Mathwich]

Hi Michele 

Thanks for your reply.

I read following information from this thread 
http://lists.scsys.co.uk/pipermail/html-formfu/2008-August/001334.html

This is why i *thought* default_empty_value should set it to "0" (the default 
value) if used.

Regarding your reply I missunderstood the behavior - default_empty_value 
causes process() to add the key to the hash if the box isn't checked, but not 
to set a default value.

Possible solutions are:

1. run through the result and set unset checkbox values to 0 
2. use transformers (like you suggested)
3. add the suggested "default_if_unchecked" to formfu

Bye, Juergen
