I've created a new ticket with your problem: http://xp-dev.com/trac/ggl2/ticket/121 > Can you confirm that you're getting the expected result, even if you > get the error at the end? An easy way to check this is to add a show 'ok'; at the end of your script. Temporal file cleaning happens after the last script line so, if 'ok' appears in the console, it means that the script run well and it is the cleaning that fails.
