The glide_list field does not honor the dictionary max_length and there is no error when a user exceeds the limit of the dictionary entry (but the value is truncated when saving).

1. Create a glide_list field on the cmdb_ci table.
   • Ensure max_length is set to 1024
   • Set the Reference to sys_user table without any filter
2. Create a new record on the cmdb_ci table.
3. Expand the glide_list and add 35 users as value.
4. Save the record.

Create an onChange Client Script to validate the length of the newValue and warn the user. For example:

if (newValue > max_length_of_dictionary_entry) {
  alert("Max number of entires exceeded");
}
