CommerceContext.Current.CatalogSystem.SetJoinTable: How to Dispose

[Souto]

Hello all!

I'm new to CS2K2 and i'm working on a big international project
maintenance.
I had a few problems with setting the SetJoinTable method but after a
couple of days this is working as i intended.
But know another problem raises from using this method.
We have a Product List page that is showing the catalog/category
products and a side menu wich should be showing all the root
categories of the catalog(GetRootCategories).
After setting the SetJoinTable the joined data stills in memory and
the GetRootCategories throws an error as Categories doesn't have a
correspondence in the joined table.

My question is how can i dispose of the SetJoinTable method after
using it before calling the GetRootCategories method?

Thanks in advance
