Facebox seems to be sending HTML instead of JS with IE7

I'm using Facebox to edit a record with my Ruby on Rails App. The Facebox pops up with edit form that I then submit to update the record with AJAX.

It works fine with Chrome, FireFox, Safari and IE8

with IE7 the link actually renders new page so it doesn't actually call AJA开发者_运维问答X and looking at server logs I see:

Processing by Admin::Products::LicenseAssignmentsController#edit as HTML (IE 7)

instead of

Processing by Admin::Products::LicenseAssignmentsController#edit as JS (other browsers)

Do you know how to resolve this?

One of the reasons that AJAX is called the order of components is required. Check the order of the javascript libraries, and look at the log (console) browser.

P. S. This error only occurs in IE7?
