[wp-hackers] meta_key and meta_value query variables don't work in the backend?

[Matthew Gerring]

What I mean is, I'm writing a plugin to allow a client to sort pages on the edit pages screen. I have it set up to sort by author, title, and date, and filter by a custom taxonomy. I want to be able to sort by custom field as well- all of the pages in this site have a custom field called "Country" with a set drop-down list of countries.

To do all the sorting and filtering so far, I used the manage_pages_query hook to add query variables to the request, and it has worked perfectly. All it does is put all the query variables in an array and pass it to the wp() function. But if I try to use the meta_key and meta_value variables, which are available if I use them in a theme (i.e. in the front end), nothing happens. So it appears that while you can pull out posts according to custom fields in a theme, you can't do the same thing on the manage pages/posts screens in the back end, and I'm wondering why.

I hope that clears it up.

They do absolutely nothing, together or separately. I dug through the source to see what was going on, but I didn't see any giveaways as to why the front end would accept that as a query variable and not the back end. Can anyone shed some light on this?
