I was writing the same issue exactly in the same time! I provided a patch in a pull request for it... ;)
Here's the content of my issue report:
In the example, the drill-down works correctly but in my case, I use a datasource which consists in an array of objects and the drill-down grid is always empty.
I have noticed that this line is the source of the problem because it iterates on data[i].length while data[i] is an object.
If I replace it by:
for(var j in data[i]) {
it works for array of arrays and array of objects.
