Dexterity Schema unaccessible after update to 5.1b4

[tomgross]

BUG/PROBLEM REPORT (OR OTHER COMMON ISSUE)

What I did:

I updated a Plone site from 5.1b3 to 5.1b4 pending.
The site has PAM installed with three languages de (default), en, fr.
The site did NOT use combinded languages.

What I expect to happen:

Schema editing in control panel works.
http://localhost:8080/Plone/dexterity-types/Document/@@fields

What actually happened:

An error was raised:

Traceback (innermost last):

Also the combined language flag changed with the update. I reset it manually but the error persists.

What version of Plone/ Addons I am using:

Plone 5.1b4 with PAM

[hvelarde]

this is happening also in Plone 4.3.11 with latest plone.app.contenttypes 1.1.1 installed:

That might be related to: plone/plone.app.dexterity#251

@hvelarde are you using plone.app.dexterity 2.4.4 instead 2.0.18?

The easiest fix would be to revert that change. I'm wondering where the language en-us comes from, in case of @tomgross problem.

/cc @jensens @mauritsvanrees opinions on how to fix this?

[tomgross]

I downgraded to plone.app.dextertiy 2.4.3 but the error still persists.

[hvelarde]

this is what I have:

$ grep dexterity bin/instance 
    '/home/hvelarde/.buildout/eggs/plone.dexterity-2.2.7-py2.7.egg',
    '/home/hvelarde/.buildout/eggs/plone.app.dexterity-2.0.18-py2.7.egg',

[thet]

@hvelarde @tomgross to be able to reproduce your problems, can you please provide me with the following info:

• what are the values for these plone.registry settings: plone.default_language and plone.available_languages (both from the Products.CMFPlone.interfaces.controlpanel.ILanguageSchema controlpanel)
• @hvelarde what's your version of plone.app.vocabularies
• @hvelarde what's your version of plone.app.dexterity

[thet]

@tomgross @hvelarde - just saw your comments regarding versions - looks like the errors are not related to my PRs:

• The ICategorization behavior should only expose those content lan… plone.app.dexterity#251
• Let plone.app.vocabularies.SupportedContentLanguages return the l… plone.app.vocabularies#50
• @@fc-properties: Apply recursively + set language plone.app.content#133

Also, it's unlikely anyways, as they should not affect the schemaeditor...

Updated a 5.1b2 multilingual (de, fr, it, en) site to 5.1b4

http://localhost:8080/Plone/dexterity-types/Document/@@fields works for me

plone.dexterity-2.5.2-py2.7.egg
plone.app.dexterity-2.4.4-py2.7.egg

[tomgross]

I have a suspect. We set the language programmatically. This was a string until Plone 5.1b3. With Plone 5.1b4 the script complained about an unicode issue for new sites. I'll try to change the language settings to unicode on our existing site and report.

[tomgross]

Yeah, this did the trick for me:

    language_tool = api.portal.get_tool(name='portal_languages')
    for lang in [u'de', u'en', u'fr']:
        language_tool.addSupportedLanguage(lang)

    portal = api.portal.get()
    ml_setup_tool = SetupMultilingualSite()
    ml_setup_tool.setupSite(portal)

[tomgross]

I'm unsure wheter this issue should be closed. Ideally an upgrade step takes care for the transition but setting the language programmatically is probably not a common use case.

[thet]

Sounds like an upgrade step among a note/warning in the incompatibilities section of the CMFPlone changelog is needed.

I'm curious what caused the problem. Must be some common package which Plone 4.3.x ( @hvelarde problem) and 5.1.x uses.

[pbauer]

I just has a related problem with 5.1b4. For me the issue was that the value for plone.available_languages was empty since since I was setting it wrong in my registry.xml. That was no issue before but now the value for 'language' in schemas gets validated against the vocabulary.

api.portal.get_registry_record('plone.available_languages') returned [] instead of ['de'] which it does in a newly created site.

My error was to set it using::

<record name="plone.available_languages" interface="Products.CMFPlone.interfaces.controlpanel.ILanguageSchema" field="available_languages">
  <value>['de']</value>
</record>

instead of

<record name="plone.available_languages" interface="Products.CMFPlone.interfaces.controlpanel.ILanguageSchema" field="available_languages">
  <value>
    <element>de</element>
  </value>
</record>

[tomgross]

I'm closing this now. The special cases for programmatically setting of languages and profile requirements are documented here for further reference.
