Using with jquery sortable

[andrei4002]

If I use jquery sortable to sort some lists (non related to file uploading, just simple lists), while there's a file upload widget enabled somewhere in the page, i get an error saying Cannot read property 'dataTransfer' of undefined from the _onDrop function on this plugin. This happens when I perform a drag and drop on my lists elements (just move elements between them, and only when I drop them)

Why could _onDrop be getting triggered when I use sortable (happens when I drop a dom item in another place) ?

Right now I monkey-patched the _onDrop function to skip if there is no e.originalEvent coming in. Any ideas?

The sortable plugin probably triggers a "drop" event that was lacking the originalEvent property.
I've added checks accordingly.
