PHP Fatal error: method_exists(): / errors revealed by views with editable fields

Also noting here: in this case, the Current Path field itself was not a part of the editable fields, it was being used in a rewrite of a "static" text displayed elsewhere in the row of data. It appears that just the presence of the field in the row of data was enough to trigger this.

Thanks for reaching out! I created a test view that recreates the issue, will follow with other notes:

^^^ In this case, I created a test view of a single node type, adding the title and another sample field (phone number, in this case), making that Phone Number field editable using the Editable Fields module version: 7.x-1.0-alpha4. This view returns multiple rows of data, in this case, hundreds of records, paged 10 at a time.

At this point, the view works as expected. A user on the site can visit that view page and edit the text in a phone number field, with the ajax form submission working properly and updating the node accordingly.

I then add a Views Current Path field to the view and exclude it from display (though it doesn't seem to matter if it is displayed or not). Now, when a user visits the page and edits an editable field, the same error occurs as posted above. The error occurs during ajax submission of the editable field from the view page. The ajax error is shown to the user, and the corresponding PHP error is recorded to the logs.

Based on a cursory search, I was wondering whether this might be related to the PHP version?? (7.2.24-0ubuntu0.18.04.1)

Happy to help, thanks for the fix and feedback. Appreciated.
