I suspect this logic should be handled by the form - not the database layer.
I'd suggest writing a HTML::FormFu::Transformer subclass to do it.

I made an HTML::FormFu transformer that just needs to set a {} instead an 
undef value for a File element, but it doesn't work. If I use the same 
transformer for a Text field, it works fine.

Is the File element special and it can't be transformed?

As a test, I put the transformer to return a static value of "blabla". It is 
returned fine for a Text element, but for the File type element, after 
applying the transformer, the value is a null one.

I have printed:

after applying the transformer, but both of them contain just a null value.
