Dexterity Content type with working copy (iterate) and workflow

Question

I'm trying to apply Formal workflow to our custom made dexterity object. Buildout has plone.app.versioningbehavior, collective.cmfeditionsdexteritycompat, collective.dexteritydiff plone.app.stagingbehavior, plone.app.referenceablebehavior.

What I'm finding is when I click checkout on it does create copy of object (copy_of_object) but ref to working copy(object) get corrupted?. At this moment if I get back to my working copy (object) its giving following error:

attributeError('getBRefs',) (Also, the following error occurred while attempting to render the standard error message, please see the event log for full details: getBRefs) 

Any help would be great. here is my full trackback
