Array: reordering is buggy about jsonform HOT 4 CLOSED

@tidoust Thanks a lot!

Any time estimate on fixing "values in nested array
are still lost during reordering for the time being"?
It's a showstopper for me right now.

Thanks!

@huyl, hopefully I'll be able to find some time this week to fix the remaining issue.

The main bug to fix lies in the getPreviousNumberOfItems function. It should also receive the current property that the code is interesting in on top of the path that leads to that property. Without that parameter, the function simply returns 0, causing all nested values to disappear.

I've been looking at AngularJS and I think it could be a great framework for implementing jsonform in such a way that the generated values JSON will always be kept in sync.

Check out this demo with sortable drag-n-drop elements in an arbitrarily deep tree:

Note that the underlying JSON will be kept in sync at all times, which is something that I need for my application (because the generated JSON is actually a form specification which I need to preview in real-time to implement a sort of wysiwig UI)

@huyl, closing the issue as I fixed the buggy getPreviousNumberOfItems function in last commit. Nested arrays now seem to work well in the playground. I may have missed some corner case though, let me know if something's still not working as expected.
