I have never been able to resolve the "Object reference not set to an instance of an object." error in the Category Menu module,  and now it looks like the "Show Categories" option has been removed from the Product Listings settings.  What am I to do now?

Details for the "Object Reference not set to an instance of an object" error:

-  If I have two Pages each with a Buy Now and a Category Menu Module the load ok
-  Which ever Category Menu module I decide to click first works but after the first postback the other Category Menu module fails
- If I reset the DNN Application, I am back to be beggining and which every menu I choose first causes the other to fail

- I have removed all other modules from the page,  and using the default dnn skin so ensure it is no other modules causing the error.  Please help as I would like to purchase 10 licenses.  Thanks.

Yes, in v4.32 just released the show categories option that displays the categories within the buynow module was removed. Can you try installing cart v4.32 in a new dnn 5.62 sandbox and see if you still get the error with the category module.

I will try to get one setup.  Quick question, is the treeview supposed to maintain it's viewstate even after I've visited a different page?  If I go to a category, then go to a different page,  or even a different website all together,  it still remains in the category I selected when I return.  Should it not go back to the default category I selected in the settings?  If I disable viewstate on the treeview control,  I don't get the "Object Reference..." error but it doesn't work right either.

Hi Mark,

Yes, the treeview will maintain the last category selected when you navigate away from the page and then back.  Make sure that you have not turned off viewstate in your web.config or disabled it on the page where the you place the category module.  Also make sure that you have session set properly in your web config to a long enough time so its not timing out.

. <system.web>

    <sessionState timeout="60" />     
</system.web

Thanks, Kevin

Will the "Show catagory" feature be re-added as I am planning to use that. As I only want specific catagories added to a particular page.

Yes we can look at re adding it in the next version. Just curious why aren't you using the category module its more flexible and I think looks better.
