Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
When attempting to rebuild a tablefield I get the following error in the DB log:
Notice: Undefined index: #ajax in ajax_form_callback() (line 395 of drupal/includes/ajax.inc).
My tablefield is currently 240 rows and 3 columns. I get this error when I change the # of columns to 4, as well as with an attempt to copy/paste in a complete 4-column data set. (running Drupal version 7.56)
