Typus save/edit form

Hi,

I have some troubles with Typus form when I want to “Save and add new”
and I want to know
if there’s anyone here that uses Typus.

What I want to know is how can I clean the fields of the form after
hitting “Save and add new”
I have a question_controller and inside I put this

def new
if params[:_addanother]
super
_evaluation = @item.evaluation_id
@item = Question.new
end
end

I was trying to render a new form, but I’m not sure if it’s ok.
Somebody uses Typus?

Thanks in advance
