There's not been any change to process_attrs() since 0.03001
What's causing the warning is the following line in your yaml:
action:
That's not necessary, as formfu always outputs an empty action="" if
you don't set one yourself.
Actually, I'm surprised that's not a syntax error - I thought you had
to explicitly set an undef like so:
action: ~
Anyway, I've fixed process_attrs() so it'll turn any undef's into an
empty string, so there won't be any warning - though your patch wasn't
quite suitable, as it would have turned any zero value="0" into an
empty string value="", which would break some radiogroups I use.
Cheers,
Carl
