    problem with form getting error stack level to deep

    dears since I'm new to ruby I try to create a form within ruby on rails.
    this is my controller
    Code:
    require "player"
class SpelersController < ApplicationController

  def index
    @speler = Speler.find(:all, :order => 'RAND()')
  end

  def all_sorted
  @heren=Speler.heren
  @dames=Speler.dames
  end

  def score_sn
  @senior=Speler.sr 
  end
 

  def score_jr
    @junior=Speler.junior
  end

  def score_p
    @pupil =Speler.pupil
  end

 def score_top
   @man =Speler.topm
  @vrouw=Speler.topv
  end
def list
if params[:id].nil?
  @spelers = Speler.find(:all)
else
  @spelers = Speler.find(:all,:conditions =>["id=?",params[:id]])
  params[:id] = nil
end  
end
def show
  @speler=Speler.find(params[:id])
end
def new
    @Speler = Speler.new

    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @Speler }
    end
  end
def create
    @speler = Speler.new(params[:speler])

    respond_to do |format|
      if @speler.save
        flash[:notice] = 'Speler is met succes aangemaakt.'
        format.html { redirect_to(@speler) }
        format.xml  { render :xml => @speler, :status => :created, :location => @speler }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @speler.errors, :status => :unprocessable_entity }
      end
    end
  end
  def edit
   @speler = Speler.find(params[:id]) 
  end
  def update
    @speler =Speler.find(params[:id])
    @speler.date = Time.now
    if @speler.update_attributes(params[:speler])
      flash[:notice] = 'de gegevens met met succes aangepast.'
      redirect_to :action => 'show', :id => @speler
    else
      render :action => 'edit'
    end
    end
 def destroy
   Speler.find(params[:id]).destroy
   redirect_to :action => 'list'
 end
  end
    this is my model

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

          [code=ruby]
          def new
          @Speler = Speler.new

          respond_to do |format|
          format.html # new.html.erb
          format.xml { render :xml => @Speler.to_xml }
          end
          end
          [/code]
