ok. I've had some time to look into this now and have figured out a few
things.
1. This is not due to calling the DGrid constructor from clojurescript. It
occurs even when I call the DGrid constructor from straight javascript
code. So it doesn't have to do with the clojurescript code calling the
constructor.
2. The error goes away if I don't require cljs.core. If cljs.core is
required then the grid constructor ends up calling back into some code in
cljs.core, which is where the error occurs.
So I'm a little further down the road but still don't know exactly why
doing a goog.require("cljs.core") causes cljs.core to receive events from
the DGrid constructor. Digging in with my javascript debugger and will
update this as I find out more information.
