Ok thank you, I think I get what your saying but I was thinking of a more specific exampel for my case. Still not sure how to preregister the vbcms_toolbar template in the vbcms_content_section_page template. I'm not even sure how vbcms_page preregister the vbcms_toolbar template in the default vb4 template. Can't find any preregistration of the vbcms_toolbar template anywhere.
I would really love if you could give me a hand in this specific case, maybe all the pieces fall into place after that.
Again, thank you for your effort.
I have exactly the same problem. I hope someone can help us.
