I've ran into a couple of times where users were not able to delete their versions. Once was because they were still connected to their version, or at least ArcMap thought they were. The other time, they received some message along the lines of "unable to delete, invalid State ID". I haven't been able to find any information on this message or why they were getting it. They were able to simply try again another day and successfully delete the version. Can anybody tell me about this?
We're new to versioned editing, basically at this point people were just experimenting with creating versions, changing versions, starting edit sessions, and deleting versions. So there wasn't much going on beyond that.
