AutocompleteFieldWidget installation issue - Uncaught ReferenceError: formwidget_autocomplete_parser

Hi,

I wish to use AutocompleteFieldWidget for a single selection from the vocabulary but encountered js-error. Here is my path:

  1. add widget dependency to buildout.cfg:
eggs =
    Plone
    Pillow
    Products.PloneHotfix20200121
    collective.taxonomy
    plone.formwidget.autocomplete
  1. declare widget usage in the schema:
directives.widget('species', AutocompleteFieldWidget, vocabulary=SPECIES_TAXONOMY_NAME_DEFAULT)
species = schema.Choice(
    title=_(u"label_animal_species", default=u"Species"),
    description=_(u"Animal species and breed"),
    vocabulary=SPECIES_TAXONOMY_NAME_DEFAULT,
    required=True,
)

  1. buildout runs fine

  2. but looks like AutocompleteFieldWidget js methods unaccessible or undefined while registering inputs in a browser:

Uncaught ReferenceError: formwidget_autocomplete_parser is not defined

It is unclear what's going wrong with the installation process

I've just stumbled upon this problem myself. The solution is to install the "plone.formwidget.autocomplete" add-on in Site Setup / Add-Ons. Or create a dependency in your Generic Setup profile, in metadata.xml.
