I have a Drupal 7 application with custom content types that had some select lists using Entity References. Our editors created new content with the custom type and selected multiple entries from the select list (ctrl+click).
Well, I decided to instead use the Auto-complete, because it was faster for the editors to use. Now when the editors visit previously developed content, the selections they used before the widget change are no longer linked to the content.
I did not remove/delete the select list widget, I just merely changed it to Auto-complete.
Any ideas on what happened and if I'll be able to get those other linked items back?
