[TYPO3-commerce] Basket gets emptied when loading commerce_ext (commerce: latest version from SVN)

[Bert Hiddink]

Hello,

Is the "commerce_ext"-extension working with the latest version of 
"commerce" from SVN?

When I load "commerce_ext and add an item in the basket, it says that my 
basket is empty???

Anyone seen this error before? Is there a SVN-version for "commerce_ext"?

Many thanks in advance!

Regards,

Bert
