Problem in conjunction with Gravity Forms Directory

i successfully created a form with your advanced file uploader. everything works fine. but when i use Gravity Forms Directory to output the entries in the frontend, i get a warning message:
Warning: Invalid argument supplied for foreach() in /Users/nicb/Data/_htdocs/batfo/wp-content/plugins/gravity-forms-advanced-file-uploader/class.core.init-uploader.php on line 1541
i then added the following statement around the foreach code:
if (is_array($file_attachment_ids)){…}
problem solved.

2nd problem: all values of each entry are shown except the one from advanced file uploader. it just shows: “View form entry for file details.”
I uploaded just one image. How can i show it in the frontend?!

THANKS
