url rewrites, pagination and posts2posts

Hello

I have a problem using posts2posts:

I link related articles on a page, ordered by a custom date field, and I want them paged. Problem is that the pagination is always showing the same results (I’m using pagenavi and already tested the multiple solutions they give).

When I disable the url rewriting… it works.

Does anyone see a solution about this?

Thanks!
