Getting Current Version in NewVers.nrs

System

We have customized our FileSave.nrs to set the document description based on various metadata fields. The code is below:

Sub IManFileSaveCmd_PostOnOK(obj)
set oImportedDoc = Context("ImportedDocument")
strDocDesc=oImportedDoc.GetAttributeByID(imProfileCustom2Description) & "_" & oImportedDoc.GetAttributeByID(imProfileCustom3) & "-" & oImportedDoc.GetAttributeByID(imProfileClass) & "-" & oImportedDoc.GetAttributeByID(imProfileSubClass) & "-" & oImportedDoc.GetAttributeByID(imProfileComment) & "_" & oImportedDoc.Number & "_v" & oImportedDoc.Version
oImportedDoc.SetAttributeByID imProfileDescription, strDocDesc
oImportedDoc.Update()
End Sub

We are trying to achieve the same result when creating a new version. However, NewVersionCmd_PostOnOK does not seem to allow the same designation of Context to "ImportedDocument". The best I can do is get the version of the current document but this doesn't do me any good as users can open an earlier version than the most recent.

Any guidance is much appreciated.
Thanks,
Ron
