[NTG-context] Needless empty page at end

Hi again! When I compile the example of http://wiki.contextgarden.net/Alternating_backgrounds_and_repeating_layers with "texexec -lua" or "-pdf" I get an additional empty page at the end of my document. It shows the watermark but neither text nor the pagenumber. This workaround unfortunately doesn't work: http://wiki.contextgarden.net/Empty_page_at_the_end Any ideas? I'm using the latest garden-minimal. Good night, Eyke
