[Seaside] Weird back button problem

[Lawrence Kellogg]

Hello,
  I noticed a weird issue with rendering the Back button. If I have 

renderBackButtonOn: html
	html break.
	html cancelButton
		class: 'btn';
		callback: [ self back ];
		value: 'Back'.
	html break

and this:

back
	self answer: false

and then this:

	html
		form: [ 
			self renderBackButtonOn: html.

			self resources do: [: each | html render: each].
			
			self renderBackButtonOn: html].
		

I often see the case where the first rendering of the Back button works correctly, but the last render does not work. I press the button and nothing happens. Any idea what is going on here?
