Problem with ajax and nested forms

Hi everybody,

I have the following problem:

My model 'event' has many 'eventdates'. I use a nested form to edit
these events and its eventdates. Everything gets updated using js,
which works fine.

def update
    @event = Event.find(params[:id])
    respond_to do |format|
      if @event.update_attributes(params[:event])
        format.html { redirect_to(@event) }
        format.js {}
      else
        format.html { render :action => "edit" }
        format.js {}
      end
    end
  end

Again, using ajax it is possible to add another eventdate to the
event.

def add_eventdate
    @event = Event.find(params[:id])
    @event.eventdates << Eventdate.new

    render :partial => "tab2", :object => @event
  end

That works fine, too. But updating the model now is reloading the page
or actually it is doing redirect_to(@event). So whenever I have added
a new child to the event-object it is not updating via ajax anymore it
seems.

Could you give me a hint what aspect I am missing?

Thanks a lot

Ok, found the problem. The submit-event wasn't captured anymore.
Thanks for reading.
