HTML5 Drag drop in Rangy

[ramthenmala]

Hi, first of all thanks for the great plugin.

i have created drag drop template builder with jquery and javascript. For text selection i m using rangy.js and have some modal fields that user may able to drag and drop in between text. But when i try to drag and drop text in rangy section console returning an error

The given range isn't in document Uncaught TypeError: Cannot read property 'end' of null(…)

do have any idea why it is happening.
