Hi, I have a document library on which versioning is enables (major & minor versions, users must checkout before editing and approval is requires). I was building some custom approval workflow and eventHandlers, when I notices there was something wrong with the version numbering. So removed the workflow from the list and deleted all eventHandlers. The problem however was not resolved. So now I have quite a basic document library with unreliable versions. Here'se an example flow document has version 0.1 (is checked in) checkout document (still 0.1) checkin again: the UI lets me choose what I want - minor: 0.2 - major: 2.0 I have chosen the major version document gets approved the version displayed in the library still is 0.1 when looking to the real data I see _Version = 0.1 and _UIVersionString = 2.0 Repeating these steps gives me the same result: _UIVersionString is updated correctly, _Version stays at 0.1. In the document library 0.1 is always shown. Does anyone know how this is possible? Thank you Regards, Hans
