re: problem with form getting error stack level to deep

I am not familiar with respond_to or your setup, but does @Speler maybe need a .to_xml in the 'new' method?

Expand|Select|Wrap|Line Numbers
  1. def new
  2.     @Speler = Speler.new
  3.  
  4.     respond_to do |format|
  5.       format.html # new.html.erb
  6.       format.xml  { render :xml => @Speler.to_xml }
  7.     end
  8. end
