Translate an IDML file. In BWB, delete a placeholder or change its order. Save the target file and you will see the following error:

"System.NotImplementedException: The method or operation is not implemented."

The previous error message did not indicate exactly which segment has problems. It has been replaced with a more specific message which points to the exact segment that causes the error.


You can fix this issue by deploying the update to WorldServer 10.4.5, available on FTP.

If you cannot deploy it, contact the SDL Support Team:

  • All systems running WorldServer 10.4.5 should have this hotfix applied.
