Adding a CheckBoxList crashes back office

[craigs100 (Craig)]

V13.7.2

Adding a checkbox list to an otherwise working docType causes an exception. thus:-

The console shows the following:-

The checkbox list isn’t anything fancy:-

I’ve deleted the umbraco/temp folder, re-built models, deleted cookies and restarted the site. Error persists. If I change it to a Toggle instead, it’s fine, so it’s definitely something wrt the checkboxlist, but I’m out of options.

I’ve had a look in the Umbraco CMS Issues tracker and I don’t see anything relevant. Does anyone have a clue as to how to fix it or is it a bug?

Thanks.

This bug/issue is still there. Desperate to use checkbox list but can’t because of this. Has anyone any clues as to what might be going on?

Can anyone confirm they have one working ok?

Thanks

Hi Craig

I’ve just tried installing a new v13.7.2 solution and built a Doctype with a working CheckboxList; works fine.

Are you replacing an existing Property with a CheckboxList? (I could see that maybe being a problem if it tries to convert existing property data).

Have you tried adding the CheckboxList to a new Doctype to test if the same error occurs?

Hey Chriztian,

Thanks for that. I took your hint about it possibly being screwed up with a previous editor. First I checked it worked ok on a test page, then put it back in to where I wanted it, after saving the docType, rebuilding models and restarting with the old editor removed. Then added in the checkbox list and so far, it seems to work.

Thanks again.
