Can't import settings from registry.xml in v0.7.2 onwards

[djowett]

Using this registry.xml

<registry>

  <record name="collective.cookiecuttr.interfaces.ICookieCuttrSettings.accept_button" interface="collective.cookiecuttr.interfaces.ICookieCuttrSettings" field="accept_button">
    <field type="plone.registry.field.List">
      <default>
        <element>{'text': u'Accept cookies', 'language': u'en'}</element>
      </default>
      <required>False</required>
      <title>Text to show in the Accept button</title>
    </field>
    <value>
      <element>{'text': u'Accept cookies', 'language': u'en'}</element>
    </value>
  </record>

</registry>

I get the following error

I believe this is the same issue mentioned in collective/collective.z3cform.datagridfield#22

[djowett]

Upgrading to latest plone.supermodel (1.2.6) doesn't fix it.

Removing the <default> tag gives this error instead:

Which looks like plone.supermodel has found the wrong converter....

[djowett]

Adding a value_type to the field in registry.xml seems to make the import work, but unfortunately the just ends up with a TypeError: ('Could not adapt', u"{'text': u'Accept cookies', 'language': u'en'}", <InterfaceClass collective.cookiecuttr.interfaces.ITextAcceptSchema>) error on the @@cookiecuttr-settings control panel.

This means that the exporthandler is also wrong somewhere as it should set a value_type

Setting value_type to collective.z3cform.datagridfield.registry.DictRow leads to a

  Module plone.app.registry.exportimport.handler, line 49, in importRegistry
  Module plone.app.registry.exportimport.handler, line 92, in importDocument
  Module plone.app.registry.exportimport.handler, line 190, in importRecord
  Module plone.supermodel.exportimport, line 113, in read
NotImplementedError: Type collective.z3cform.datagridfield.registry.DictRow used for value_type not supported

My registry.xml now looks like this:

<registry>

  <record name="collective.cookiecuttr.interfaces.ICookieCuttrSettings.accept_button" interface="collective.cookiecuttr.interfaces.ICookieCuttrSettings" field="accept_button">
    <field type="plone.registry.field.List">
      <required>False</required>
      <title>Text to show in the Accept button</title>
      <value_type type="collective.z3cform.datagridfield.registry.DictRow"/>
    </field>
    <value>
      <element>{'text': u'Accept cookies', 'language': u'en'}</element>
    </value>
  </record>

</registry>

I'm going to leave this here for now and just pin to 0.7.1 of collective.cookiecuttr. The issue is almost certainly within collective.z3cform.datagridfield, but perhaps we could use an alternative?

Does anyone have the GS import working since 0.7.2 ?

[djowett]

Still an issue don't know whether this is maybe to do with me using plone.app.contenttypes on Plone 4.3

[djowett]

@erral @kingel sorry to ping you directly on this, but can you just say if you've seen this problem? Should I be trying to save the settings to a GS profile or is that silly to attempt it?

[erral]

Sorry... No, I haven't seen this problem before, but we didn't try to save the information in the GS profile and then import back.

[djowett]

Thanks for the reply.

If this isn't working, would you agree that we may need to rework the
multilanguage solution so that it does?

[erral]

Yes, or at least the import/export steps.

[djowett]

Ok, yes - I figure the export is wrong somehow, so that's the first
thing I'll try,
but it might come to fixing the form.

[kingel]

No idea, but to be honest we havent used the package for years now :)
