How Do You Get The Selected Items From A Dragstart Event In Chrome? Is DataTransfer.getData Broken?

I am part of a team that works on a Java application that, among other things, helps people organize and annotate information from the web. We currently use a Firefox plug-in that

Solution 1:

WebKit, and hence Chrome, is quite restrictive on when you can call getData. You're not allowed to do it inside dragstart or dragover. I think this is the canonical bug.

Solution 2:

Paste this line before the error line:

event.dataTransfer = event.originalEvent.dataTransfer;

This worked for me.
