we are getting error “Cannot read property ‘isLevel’ of undefined” when removing items from “Drop & Arrange Values”. Doesn’t happen always. It is also reproducable on your demo version. Usually happens when removing last item in the list, when there are couple of items.
See attached screenshot.
We were using latest 2.3.
Thank you for reporting.
From the screenshot, we see that the exception exists.
But we haven’t managed to reproduce it on our site.
Could you please share a video how to reproduce it?
Also, what is the result of the exception?
Does dragging stop working as expected after it?
It can be reproduced like so:
Drag and drop appears to work after the error.
Thank you for the detailed explanation. We have reproduced the issue on our side. The fix will be ready in the version 2.309 ETA Feb13.
I noticed that of 2.309v issue still exists. I was able to recreate it on site and with downloaded version.
Was fix targeted for 2.309v or is it planned for some future release ?
