I need a contextual filter in a view to search for nodes in the proximity of a city given in the url. I used the openlayer locator feature (http://drupal.org/project/ol_locator) to get started and it works as promised with normal (non-contextual that is) filters.

However, according to the thread #1469956: [Meta] - Improve Views-powered Geofield proximity searches comment #59 there should be a contextual filter in version 7.x-2.x of the openlayer_proximity module which I have installed. However, there is none in my setup. Furthermore, there is this comment #1 to the thread with the promissing name of "Cant find Views contextual filter for proximity" that the filter was renamed, but I cannot find it nevertheless.

Was this feature removed again or am I missing something obvious?

Thanks a lot!
Christian
