I have created 4 instances of the Smith.BuyNow on 4 separate pages. Into each store I've imported just over 100 products. Since each store has the same category names and the import procedure does not know which store it is importing into, I imported them with unique category names to avoid having all the products imported into the first store. I then went in and renamed the categories to be the proper display names. I added the category menu to the same page as the first store and all worked fine, then added it to the second store page and I get the error, object referenced not set to an instance of an object. If I delete the first instance of the category menu I can get the second one to work but then the first one wont. I am unable to have multiple category menu for multiple stores on one portal. Please help as I am unable to complete the project. Below is the log message:

I think I was able to replicate the problem on the test site. Could it have to do with the viewstate of the treeview control? I noticed that it maintains it state even after I've left the page.
