Title: CoreData Versioning in XCode4
The docs and operation seem contradictory.  I already have a versioned database and am trying to create a third version.  According to the docs, adding a version creates a COPY of DataModel as “Datamodel 2”.  However, the “Add Model Version” has a “new version” field, by default named “DataModel 2” based on the selected data model.  It then creates “DataModel 2” below the “from” data model.

If that’s not bad enough, the ‘Add Model Version” dialog has different behaviors depending on whether you hit the return key or the “Finish” button.  In the former case, it uses the name you entered.  In the latter, it ignores it and names it “DateModel 2”.  After deleting the new model and trying to recreate it a time or two, it crashed XCode.

I finally found the selection for current data model in the inspector
.  But could someone please tell me for sure which version is which, so I can properly migrate the chain?
