Hello. I’m experiencing the same issue. Because it was happening on a site with quite a few Plugins, I installed a fresh copy of WordPress with only Advanced Custom Fields and the Repeater Field Add-on. With only those two plugins, and the base 2014 theme, I’m unable to get the image nested inside of the Repeater to work. If I use only the image field, the single image works fine by popping-up the Media Library. The “Add Row” button does work, but then the “Add Image” button doesn’t trigger.
I attempted to use the JS noted above inside appended to the input.js file, but that doesn’t seem to help either.
