Paramtric Search Authors – Revisited 1 year later

Hi,

I'm trying to create a select dropdown of authors – parametric search. Am I correct that this still doesn't work? I had this conversation nearly a year ago:

http://wp-types.com/forums/topic/parametric-search-by-author/

So I got it working with the added function, but wondering if there's a Types/Views method by now, as the documentation says there is:

http://wp-types.com/documentation/user-guides/filtering-views-query-by-author/?utm_source=viewsplugin&utm_campaign=views&utm_medium=edit-view-author-filter&utm_term=Learn%20about%20filtering%20by%20Post%20Author

ANYWAY:

Furthering this question with a particular need:

In a simple Parametric search of 1 Post-Type, I want to return a select/dropdown list of all users/authors who created a post. The above code gives me ALL users. I only want the ones that made a post in this post-type.

A Types/Views solution would be best. If we need to delve back into that function code; I'm guessing we'd need to add in an IF and test against the posts – not sure where I'd start running such a test though.

THANKS!
