Unable to add content to new Plone site: ValueError: Unable to find update_version_before_edit exception

Question

Just finished a successful install of Plone 4.2.1 on CentOs using the unified installer. Once logged in I cannot add any content.

I get the following error:

Traceback (innermost last):

    Module ZPublisher.Publish, line 126, in publish
    Module ZPublisher.mapply, line 77, in mapply
    Module ZPublisher.Publish, line 46, in call_object

    Module Products.CMFFormController.Actions.TraverseTo, line 35, in __call__
ValueError: Unable to find update_version_before_edit 

I've already run bin/buildout -n to update components. Thanks in advance for any help.

Answer 1

I had the same issue today with a Plone 4.1.6. Here's a workaround:

Go to zmi -> portal_setup -> tab "import" -> select "CMFEditions" in the dropdown menu -> than hit the "import all steps" button.

The problem is that for some reason, that I couldn't find yet, the skin layer of Product.CMFEditions is not registered in the portal_skins and so when you try to create a content type that is under versioning it fails because of this. I'll investigate it more deeply but in the meanwhile this trick does its job.
