GenericTabularInline how to show info in both admins

Hi everyone, I hope I will explain it clear.

I created a generic relationship between 2 models, I created the 2 admins and like in lessons 15 and 16 in the admin section I added the GenericTabularInline to the “product admin” and it works fine.

What I would like to achieve now is to have the products connected to the Tag to show in the Tag editor same in the product editor with a GenericTabularInline, but once I recreate the same code for the Tag it allow me to select the Products but doesn’t show the connected ones nor in the tag or in the products.

Hope someone can help me figure how to make the Tag to show the products added in the admin area.
