While working on a vanilla implementation from the CDN on localhost, I encountered an issue I can't seem to replicate consistently. It mainly happens when dragging items near the bottom of the list. The dragging tool-tip isn't locking to the mouse as expected; instead, it keeps getting appended to the bottom of the document and won't disappear.
This persistent tool-tip causes problems when trying to use the drag-and-drop functionality repeatedly.
Upon checking the console errors in Chrome and Firebug, I always get the same message:
Chrome:
Uncaught TypeError: Cannot read property 'type' of undefined Source.xd.js:8
Firebug:
_a.getItem(_b[i].id) is undefined
window[(typeof (djConfig)!="undefined"..._4.dnd.AutoSource(_3d,_3c);}});}}};}); Source.xd.js (line 8)
Unfortunately, Internet Explorer's error message wasn't very helpful in resolving this issue.
I would greatly appreciate any assistance! I have created a simplified version of my page on jsfiddle, which you can access here: http://jsfiddle.net/ykNJ8/
Upon testing it, I can confirm that the error occurs within the fiddle environment as well.
