Just for the record, (last week) I too got the same message after my first saveandcommit of a new vwxw file.
I cleared the metadata and created a new vwxw file and had not seen the error repeated since.
Can someone tell me if there's a shortcut to change the visibilities of objects I select? I.E. select several objects of which have different classes and change the class visibility of all of them at once.
Thanks and sorry if this has been covered already.
