[TYPO3-dev] realurl shop menu and leaving out the category on article page

[Simon Schaufelberger (Schaufi)]

Hi,
i still find it hard to configure realurl the way i want it and i hope 
somebody can help me.

i have a menu with links like this:

index.php?id=4&tx_myext[shop][cat]=1

which will be transformed into:

shop/category/categoryname.html

so far so good. now i want to make a link to an article but for the menu 
to stay expanded i also need to add the cat to the url BUT i DONT'T want 
to have the cat in the url like on other shop systems so in other words 
i want this:

index.php?id=4&tx_myext[shop][cat]=1&tx_myext[shop][article]=2

which should be transformed into:

shop/article/articlename.html

but HOW do i do that??? Realurl should know that article 2 has the cat 1 
"included".

i tried playing around with the bypass setting but this didn't work out.
