image disables entity reference field

I have the same issue, but it occurs when I use a file field or an image field. I suspect this is somehow related to ajax events. If I select a file but don't press the "Upload button" it works fine. However if I do press "Upload" (Which fires and ajax event) I get the same error you see:

An illegal choice has been detected. Please contact the site administrator.

I've also noticed that removing a file or image (via the remove button, which also cause an ajax event) will throw this error.

Once the error has been thrown my drop down of entities is blank. If I cancel and go back to edit the content type my entities come back.

Any fix or workaround for this?

Having the same issue - any ideas? I found this: https://www.drupal.org/node/1045208 but still no solution

I am using the patch (#5) I wrote on this post: https://www.drupal.org/node/2358049
to fix the issue. The problem is related to Views and ajax. If it works for you please leave feed back on that page.

FYI, anyone looking for more information on this issue may want to check out these posts as well. I found them while researching the issue:

Applied the patch and it didn't work, but that is probably because I'm having the issue on an Entityform. Should have read it first before excitedly applying.

Hi infinet

No fix yet. I put this on the back burner for a couple of weeks and am just coming back to it today.

I think my issue to do with Views.
