TypeError: tagCache[tag_id] is undefined

Hi,
this error stops ckeditor and throw error in firebug console after clicking any CKeditor button

TypeError: tagCache[tag_id] is undefined
var tag = tagCache[tag_id].tag;

on line 1030 col 23

I have installed latest CKEditor 7.x-1.17 and Asset 7.x-1.0-beta4+52-dev

I think its related to Assets in wysiwyg isn't added to js cache on page load

I needed really fast solution then i used this patch #8 (thanks eugene.ilyin ) and override (like "be silent please..") at last condition (row 1037) in file asset/ckeditor/plugin.js, from:

if (element.attributes && element.attributes['data-asset-cid']) {
                  var tag_id = element.attributes['data-asset-cid'];

                  var tag = tagCache[tag_id].tag;
                  tag = tag.replace(/</g, '&lt;');
                  tag = tag.replace(/>/g, '&gt;');

                  var tagEl = new CKEDITOR.htmlParser.fragment.fromHtml(tag);
                  return tagEl.children[0];
                }

                return element;

to

if (element.attributes && element.attributes['data-asset-cid']) {
                var tag_id = element.attributes['data-asset-cid'];
			  if (typeof(tagCache[tag_id]) == 'undefined') {
					// nothing to do
				  } else {
					  var tag = tagCache[tag_id].tag;
					  tag = tag.replace(/</g, '&lt;');
                  tag = tag.replace(/>/g, '&gt;');

                  var tagEl = new CKEDITOR.htmlParser.fragment.fromHtml(tag);
                  return tagEl.children[0];
				  }
                  
                }

                return element;

Thanks for advice
