[TYPO3-commerce] Dropdown Fields for Articel/Attributes

[seg]

Hi!
Is there anybody who gets the dropdown fields working?! 
I tried it with some configurations but it still does not work in the newest svn version.
There are still 2 form tags nested around the dopdown fields... I think this could be the reason..

The JavaScript Error Message is something like that:
Fehler: document.getElementById("attList_3") has no properties
