Because you are asking in javascript the parent of a component what is null.
The reason for this is with this question very hard to see and you should check with developer tools where this error comes from.

Hi sebjose,

we can't help about SAP hybris in this forum (so please contact your support there). In case this problem also happens with pure ZK without SAP hybris, can you please post the details again (I increased your karma so you should be able to attach files or link details)

Thanks again for the screenshot and the stack trace. Now we are a step closer...

ckez.wpd

indicates a problem happening in the CkEditor widget

open / onVParent

indicate something happening in combination with a popup or tooltip.

Cannot read property 'parent' of null

Is the similar to a NullPointerException happening somewhere in the _isChildOf method

https://github.com/zkoss/zkckeditor/blob/master/ckez/src/archive/web/js/ckez/CKeditor.js#L225-L235

How it gets to this state I can't tell at the moment... can you please state your ckeditor version used in your case? You can check it using the following JS call at your Browser's developer console:

zk.getVersion('ckez')

e.g. "4.4.6.3" (printed in my case)

Based on that we can try to isolate the problem in zkfiddle without SAP Hybris around it.

unfortunately 4.0 doesn't mean a lot due to ZKCK-21, so it could mean anything between 4.0.1.0 and 4.4.6.1

I tried this simple example which goes through that code without causing that issue.

<zk>
  <button popup="pop" label="open popup with editor"/>
  <popup id="pop">
    <div>
        <ckeditor/>
    </div>
  </popup>
</zk>

Can you try this in your environment, maybe it already fails. Otherwise your '+' button is doing something different I am not aware of. In this case I'd need the details of what UI changes this button is causing. This information is found in the AJAX response body of the request containing the click event.
