TypeError: null is not an object (evaluating 'effect.body[key].constructor')

Been stumped on this one. We got the 'pageY undefined' bug fixed from #134 but now, in the same view that was giving the pageY undefined is now giving us this error. The Sortable Listview works great when it's one sortable listview, but when we allow people to move an item from one section to another, we get this crash.


Anyone else getting this?

Reproduce the crash in the React Native sortable ListView when moving an item between sections, then start from the reported expression effect.body[key].constructor and its surrounding stack trace. Done means cross-section moves no longer raise this TypeError while a single sortable list continues to work.
