eload-select's Issues

Breaks with geokit

Geokit allows you to make a model mappable through an associated model. So if user is mappable and has lat, lng columns then another model Post can be mappable through user without having lat, lng columns.

So a typical search like User.find(:all, :origin => 'new york, ca', :within => 10) works just fine. but
Post.find(:all, :origin => 'new york, ca', :within => 10) breaks with a long trace.
