The Holy Grail of Plone workflow

We are in the process of implementing a Plone CMS as a repository for ISO9001-documents.

ISO demands a certain amount of logging, as anyone familiar with the standard probably knows :-)

For the sake of flexibility we would like to incorporate, in no specific order:

New contenttypes : necessary to incorporate the different documents that can arise in an enterprise
Versioning: to show that our documents are always up to date, and to show which changes were made vs a previous version of the same document
Working copy support: so that a "published" document stays online while it is being edited
More complex workflow: to account for the review processes which are obligated by ISO
Different workflow for different documents: as workflow are dependent on the type of the document.

Therefore, the holy grail of workflow optimisation should be (and please correct me if I'm wrong):

Dexterity for the content types
CMFEdition (embedded in Plone) for versioning
Iterate for working copy support
plone.app.workflowmanager for the new workflows
Products.CMFPlacefulWorkflow for the different workflows according to different documents

The problem is the integration of the different products:

How do you get versioning to work with Dexterity?
How do you add working copies on top of that (keeping the necessary versioning)?
And how do you get your shiny new workflow (great UI btw for workflowmanager) to play nice with both versioning AND working copies.

I scoured the google-realm and already found these links:

Working copies and workflows : http://plone.org/products/iterate/documentation/how-to/working-copy-workflow-customization
Dexterity and Versioning: http://plone.org/products/dexterity/documentation/how-to/adding-versioning-to-dexterity-content-types

We also checked out:

Archetypes contenttypes versioning: http://plone.org/documentation/manual/developer-manual/archetypes/appendix-practicals/enabling-versioning-on-your-custom-content-types

which are all installed and configured...

However, my new content type does not allow for checkout/checkin (Iterate product), and neither are versions/changes tracked in the history-view for this same contenttype.

Is their a magical sequence to follow or am I missing something (or alot -which is more likely)? Because if all these products were to work "out of the box" in my opinion this is a catchall solution to all things workflow...

addition 2012/04/17: As remarked by thet, the stack is completed with both

versioningbehavior for Dexterity: http://pypi.python.org/pypi/plone.app.versioningbehavior
stagingbehavior fro Dexterity: http://pypi.python.org/pypi/plone.app.stagingbehavior

Solution

You need to use plone.app.stagingbehavior (http://pypi.python.org/pypi/plone.app.stagingbehavior), which links Iterate/CMFEditions to Dexterity types. Not sure about your versioning issues.
