Alternative solution to the original problem:
replace url '/path/to/my-article/page-2' with '/path/to/my-article/page/2'.
'page' is view_name, 2 is subpath
Alternative solution to my problem:
Create own traverser inheriting from
pyramid.traversal.ResourceTreeTraverser, using
'traversing = super().__call__(request)' and manipulating
traversing['view_name'] if it isDigit()
Hope it's still relevant,
kind regards,
Dieter
