Hi everyone.I am trying unsuccessfully to modify the version number of a node. Here is my code :newVersion = DAPI.GetVersion(myDapiNode, 0)newVersion.pNumber = newVersion.pNumber - 1result = DAPI.UpdateVersion(newVersion)The returned value is 0 (so no error), but the version number doesn't change in the LL interface.What am I doing wrong???
