AjaxSelectWidget: Saved Value from SimpleVocabulary displayed wrong

[pbauer]

AjaxSelectWidget displays the value instead of the tile of a item from a SimpleVocabulary.

To reproduce create a dx-content type wit a field using the AjaxSelectFieldWidget and a SimpleVocabulary.

DummyVocabulary = SimpleVocabulary(
    [SimpleTerm(value=u'gold', title=_(u'Gold Sponsor')),
     SimpleTerm(value=u'silver', title=_(u'Silver Sponsor'))])

Use it in a schema:

dummyfield = schema.List(
    title=_(u'Dummy'),
    value_type=schema.Choice(
        title=_(u'Dummy'),
        vocabulary=DummyVocabulary),
    required=False,
)
form.widget(
    'dummyfield',
    AjaxSelectFieldWidget,
    vocabulary=DummyVocabulary,
)

When I edit the field I see the correct options (e.g. "Gold Sponsor"). That is also used when I select a value. But after saving a value and when re-editing the object the saved value displayed in the field will now be "gold" instead of "Gold Sponsor".

The problem does not appear when using a NamedVocabulary:

@implementer(IVocabularyFactory)
class DummyVocabulary(object):

    def __call__(self, context):
        return SimpleVocabulary([
            SimpleTerm(value=u'gold', title=_(u'Gold Sponsor')),
            SimpleTerm(value=u'silver', title=_(u'Silver Sponsor')),
        ])

DummyVocabularyFactory = DummyVocabulary()

registered like this:

  <utility
    component=".dummy.DummyVocabularyFactory"
    name="mypackage.DummyVocabulary"
    />

Used in the schema like this:

dummyfield = schema.List(
    title=_(u'Dummy'),
    value_type=schema.Choice(
        title=_(u'Dummy'),
        vocabulary='mypackage.DummyVocabulary'),
    required=False,
)
form.widget(
    'dummyfield',
    AjaxSelectFieldWidget,
    vocabulary='mypackage.DummyVocabulary',
)

I think you want to use SelectFieldWidget instead of the ajax widget. ajax widget is for dynamic vocabularies.

[pbauer]

@vangheem you are right. SelectFieldWidget works perfectly with a static vocabulary.

sounds a bit as if it would be related to plone/plone.app.content#34 " Fix encoding problems with Mockup Select2 widget" where I was probably doing a mistake. don't know yet, though.
