[ic] Setting values in tags

[René]

Hi All!

I am trying to solve probably a very easy problem, but currently my 
brain just stands still and won't help me :-(

I'm replacing the product_tree-menu with a Bootstrap accordion-menu, and 
I want it to keep the menu open at the right product_group when I'm 
browsing down to item-level or category-level.

To be able to catch the current product_group and category, i have 
modified the ncheck_category-tag to save the current prod_group and 
category by adding this to the right place of the tag:

$::Values->{prod_group} = "$prod_group";
$::Values->{category} = "$category";

I get these values nicely set, but they tend to get "stuck", so if i get 
to a non-product page like index.html, these values are still with the 
old value set, and they get cleared only after a page-refresh..

What should i do so that i can use the session for storing values that 
are valid only for the current page, and are "forgotten" when the next 
page is loadedd or the value is not more set by the ncheck_category.tag?

Best Regards from Finland
