InfoPath 2010 and Sandboxed Solutions - Sort data in repeating tables using managed code

This week’s InfoPath video demo continues the theme of SharePoint list customization in InfoPath. In the 1st video in this series, Daniel Broekman showed how you can take an existing list on SharePoint and customize the form for that list in InfoPath.
In this week’s video demo, Ines Khelifi, a developer on the InfoPath team shows how you can create a
new SharePoint list and custom form directly from InfoPath Designer.
This video is also available on the
InfoPath Team Blog.
Hi Ines, I want to thank you for the very well done Demo.
unfortunately, I have a little problem. In fact when I specify the location off the Sharepoint Site as you describe on your Demo, I get the following error message " Impossible to finish this operation ( Fr : Impossible de terminer l'opération)
Would you mind helping me to solve this problem
Thanks.
