Error when focusing editor

[max-zinn]

When I click on my textarea for editing, I get the following error:

And here is my code:

<textarea name="tags" id="tags" data-placeholder="Enter tags..." data-available-tags="" class="tag-editor-hidden-src">
    tag1,tag2,tag3,tag4,tag5,tag6
</textarea>

$(function() {
	$('#li-page-tags textarea').tagEditor({
		delimiter: ',',
		sortable: false
	});
});

My usage so far seems to be really basic so I didn't expect any error. Am I missing something?

Found the solution by myself... "Read the docs, think about them, handle..."
I simply didn't import the jquery caret plugin.
