Unable to switch to Source if the edited content has a macro call that doesn't produce visible output

Update: It seems like the velocity content in the page is causing this issue. If I remove the below mentioned velocity tag from the page, then the issue goes away. But as soon as I place it back, the Source mode goes back into spinning mode.

{{velocity}}
$xwiki.ssfx.use("js/xwiki/table/table.css")
$xwiki.jsfx.use("js/xwiki/table/tablefilterNsort.js", true)
{{/velocity}}

Is there something wrong with this velocity snippet, or does the CKEditor not work well with velocity code?

Thanks.

The CKEditor is AWESOME. I love the image upload, and drag and drop functionality. Overall, the WYSIWYG part of the editor is really slick and easy to use. Thank you for all your hardwork.

I ran into this error when trying to switch between source and wysiwyg mode for certain pages. I have some pages and when I click on 'Source' button, all I see is the spinner on the source button but the source-content in the text-area never gets displayed and shows a blank text-area. Then I checked my browser to see if there's a JS error, and indeed there was one error which probably is the reason why the source doesn't display. I've attached the screenshot of the error, and screenshot of the editor.

Now, I don't see this happening on all pages. Most pages actually work fine. It is only one some pages that I run into this error. I picked 'Critical' as the priority because even though the issue is not happening for all pages, but still given how important source-mode is to some users, it can be a blocking issue for them.

The page that it failed on had following types of content:

• Table of contents macro
• Velocity macro to sort and filter a table. The code used here is:

  {{velocity}}
  $xwiki.ssfx.use("js/xwiki/table/table.css")
  $xwiki.jsfx.use("js/xwiki/table/tablefilterNsort.js", true)
  {{/velocity}}
  

• two tables

Once again, I want to thank you for this awesome editor, it really raises the bar on UX. Hopefully this is a quick fix.
