I'm using Panels to override the taxonomy display at taxonomy/term. I just enabled the term_view page that comes with Panels and it works great.
So going to mysite/colours/blue shows the Panels page no problem.
Now I want to add a View to the panel that lists the returned nodes. I create the view, and add a relationship 'Content: taxonomy terms on node' (selecting the required vocabulary 'colours').
The I add an argument (contextual filter) on 'Taxonomy term: name'. This works great in the view preview if I enter the value 'blue' but not if I enter 'colours/blue' (no results). And it doesn't work in the panel because 'colours/blue' are the arguments being passed to it.
How do I get the view argument to work with this URL?
