When saving a table to a file that is opened, no error is shown

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?

Slicer 4.11-2019-05-13
Windows 7

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