[patch] getSelectedHTML returns 'undefined' if the selection is an image in IE.

[patrick@…]

Calling createRange with an image being active (ex: after a click on it) returns a controlRange in IE, not a textRange. Thus, in line 3156 of htmlarea.js :

existing = range.htmlText

existing becomes undefined.

I've made a dirty hack catching length of the range to detect the existence of a controlRange and return the outerHTML of it's first item :

existing = (range.length == 1) ? range(0).outerHTML : range.htmlText;

There should be a better way to do it :)
