Data salad when editing taxonomy terms using data field

Can you take some screenshots of your config? I can't figure out your problem. I guess you didn't configure the bundle in the second save. In the widget, you didn't select the right widget. Try dev, it might fix it.

Thank you for your quick response. This is my field configuration, I did select the bundle on the second save.

    note:
      label: Note
      list: false
      allowed_values: ''
      required: false

I kept the default form configuration for the field, it is set to autocomplete.

  field_bibliography:
    type: data_field_table_widget
    weight: 3
    region: content
    settings:
      inline: false
      field_reference: ''
      widget_settings: {  }
    third_party_settings: {  }

Thank you for responding. The field configuration file (I did select the bundle on second save):

      allowed_values: ''
      required: false

I kept the default configuration of the form (autocomplete):

  field_bibliography:
    type: data_field_table_widget
    weight: 3
    region: content
    settings:
      inline: false
      field_reference: ''
      widget_settings: {  }
    third_party_settings: {  }

I did have the bundle selected and I have the default autocomplete widget selected.

The problem seems to be caused by getFormElement(). The value of $element["#default_value"] was a numeric string containing the entity id. Therefore the string condition was applied but the regex did not match anything because the entity id was not in brackets. The code then tried searching for any node matching the query and since my titles contain numbers, it often selected the wrong reference.

To fix the issue, it was enough to replace if for elseif on line 84 of https://git.drupalcode.org/project/datafield/-/blob/2.0.5/src/Plugin/DataField/FieldWidget/EntityReferenceAutocompleteWidget.php This way the is_numeric condition correctly identifies the entity id.

it means line 84

if (empty($entity_id) && is_string($element["#default_value"])) {
...

Could you check it?

The committed fix looks good, thank you.
