So, we've upgraded our (not yet ready for prime time) store to v2.0.
I've added the loader.js just above the closing body tag, removed the old js call in the head section. (We are loading jQuery - v1.10.1.min & jquery-migrate-1.2.1.min in the head section ... so I assume the loader "sees" this).
We have a previous mini-cart & (multiple) products fields set on the sample page.
The mini-cart seems to be functioning correctly (and reports correct # of cart contents), but the side-cart, after loading, is persistently "empty". (DIV is created, but there's nothing in it).
Just for grins, I tossed in the "sample code" verbatim, but it yields the same results.
You can see the behaviour on the page here: http://goo.gl/bMDgJQ
FWIW ... Firebug shows that everything (js, css, etc) is loading fine.
Please advise and TIA.
OH ... by right-clicking the mini-cart & opening in a new tab or window, a correct cart shows. (Got to be something with the JS not working?)
