Re: formfill strips all values

Actually, for checkboxes, htmlfill compares the value in the 'defaults'
dictionary against the 'value' attribute of the input checkbox element
to decide if the 'checked' attribute should be set. So you can tell it
to uncheck the box by explicitly setting the appropriate key in defaults
to None (or anything else that doesn't equal the value attribute).

Is there any other form field types that could cause a problem with
this?

In my case the desired functionality really belongs on the client side
(used interactively with JavaScript) and shouldn't be scattered around
in my controllers. The maximum functionality I think would be ok in the
controller would be to tell htmlfill to leave alone unspecified values
otherwise it all starts to turn into a mess.

Cheers,
Przemek

I don't see a way to distinguish between unset values in the values sent

to render, and actual values that are empty.  For instance, an unchecked

checkbox is just no value at all.

Can you put the defaults into the dictionary you pass into render?
