Adding the "products in this category" again

[vladyn]

Hello everybody,
I;ve somehow removed the list of related products in "this" category, when you are on a single product view.

Does anybody have idea how this can be added again?

I have the modules in themes/themename folder - modules/productscatedory but how this can be linked / included in the products.tpl?


EDIT:
ahh I've remembered how this was removed - it was not from the code in templates, but it was in modules - position and was written as exception "product.php". So how this can be undone.

Every time when I opening the edit position from back-end I'm getting empty field for exceptions. I've tried with blank - but no success. Where the exception variables can be found ?
