When trying to save a tablenode to a file that is open (using `slicer.util.saveNode`), the debug log shows:

`[ERROR][VTK] 19.08.2019 12:16:13 [vtkDelimitedTextWriter (000000001D364F00)] (D:\D\P\Slicer-0-build\VTK\IO\Core\vtkDelimitedTextWriter.cxx:91) - Unable to open file`

However, `slicer.util.saveNode` still returns `True`. How can I detect if Slicer stored the table successfully from my script?

Thanks for reporting this. I’ve fixed this now (in r28455).
