We are writing an integration against SP2013 and trying to leverage the CMIS Producer. We are noticing that even if we supply Version Comments to a document we are versioning, they are stored and available through the traditional SP web interface (browsing through the Site/Library). However, they are never returned as part of the document's properties via CMIS (they should be available in checkinComment, I believe). We have tried retrieving them via dotCMIS and trying to view the documents via Apache Workbench. None of the documents ever show that property being set (despite being able to see the value via the traditional interface, as mentioned).
Has anyone else notice this? Is this a bug?
