addfirstcategorydate and ordermethod do not work on namespaces
Fragment of a discussion from Extension talk:DynamicPageList (Wikimedia)
I assume you mean if the query had a namespace clause but no category clauses? addfirstcategorydate needs a category to work with since it adds the date the page was added to the category. Ordermethod should work without a category clause, but some ordermethods (such as ordering by categoryadd) won't for obvious reasons. Which ordermethod isn't working for you?
