Re: $paginator->link sorting – Is this a Bug?

As there was no reply I ended up posting a bug ticket for this. I'm
posting the result here for future searches on the subject.

Apparently this inheritance is the intended behavior of the Paginator
helper. Personally this makes no sense to me, but I guess there must
be good reason for it.

If you need a link that doesn't adapt to the current parameters (e.g.
having a permanent direction:desc) then it's recommended to use
HtmlHelper::link. The links generated with this do not change, thus
giving the desired results.

For example, in my index.ctp view I changed;

echo $paginator->link('Recent', array('sort'=>'released',>
'direction'=>'desc');

to

echo $html->link('Recent', array('sort' => 'released', 'direction' =>
'desc'));
