I'm working on a solution using FME Server's datadownload service on which I'm trying to write out to a DWG with an uploaded template file (via the datadownload web gui).
Currently it fails with the log error:
Failed to copy template file '\\prototyp.dwg' as the destination file 'C:\\Windows\\TEMP\\FME_1360689826165_4428.dwg'. Error is 'The operation completed successfully.
A fatal error has occurred. Check the logfile above for details
which is funny because it says it completed successfully but obviously it didn't.
The test case I'm running is just a DWG reader connected to a DWG writer with the writer's template parameter published. If I remove the published parameter and provide the template as a resource the workspace translates successfully.
I've checked the permission on C:/Windows/Temp and even tried with permission to Everyone on full. The FME Server is running on Windows Server 2008 R2.
