[TYPO3-commerce] wrong backlink to categorie (on the Detail-View)

[Frank K.]

Hi erverybody,

My Problem is, that the Categorie-Links on the Detail-View of the Products 
alway link to the ROOTCATECORIE and not to their "own" Categorie because of 
a wrong syntax in the GET-String.

LINK EXAMPLE:
a Product links to:
index.php?id=84&no_cache=1&catUid=7

but the correct link must have been :
index.php?id=84&tx_commerce_pi1[catUid]=7

you see, the ID of the Categorie is correct but the link is generated 
wrong...

So whats wrong with my settings !?

Thanks a lot

Frank
