If the empty field is indeed not showing up in the body parameters  
list in Catalyst (meaning that the debug table that Catalyst prints  
out when you submit a form doesn't contain a value for that field,  
but does contain a value for other fields) then I would start by  
trying a different browser, if your browser doesn't submit a value  
for empty fields, then it's broken.

On the other hand, if you don't see the "Body Parameters are:"  
followed by a list of the parameters in the debug output when you  
submit the form, then your Catalyst app may have parse_on_demand set  
in it's configuration, which means Catalyst won't automatically parse  
your submitted parameters, and you have to do it yourself (or turn  
parse_on_demand off).
