how to manage errors in ARes?

how to manage errors in ARes? Hey all,

I have that function:

def create     @profile = Profile.new(params[:profile])

    respond_to do |format|       if @profile.save         flash[:notice] = 'Profile was successfully created.'         format.html { redirect_to profile_url(@profile) }         format.xml { head :created, :location => profile_url(@profile) }       else         format.html { render :action => "new" }         format.xml { render :xml => @profile.errors.to_xml }       end     end   end

Now when I create a profile from ARes with wrong information, I don't get the same error I would get normally. I only get some http errors, not the activeRecord ones, isn't @profile.errors.to_xml supposed to send me the ActiveRecord errors? if yes, how can I get that errors.xml then?

Thanx in advance
