TinyMCE – r has no properties

Occurs in firefox when there’s a textarea in a hidden div.

Change in tiny_mce.js


IsCollapsed: function () (
This.getRng var r = ();
if(r.item)return false;
return r.boundingWidth==0||this.getSel().isCollapsed
)


to


IsCollapsed: function () (
This.getRng var r = ();
if(r==null||r.item)return false;
return r.boundingWidth==0||this.getSel().isCollapsed
)
