Adapt CsvNameExport to rollback only and generally review where and how it should be used
To make the 2 CsvNameExport tests in TaxEditor test environment not fail, read only was set to false in CsvNameExport (line 207)
If readonly = true the rollback throws an exception in the service layer which is not correctly handled in the tests (and maybe also not real exports).
However, we need to discuss if we need these exports at all after CDM light is now available. They werde developed for print publication of Cuba checklist and Caryophyllales genera.
These can be done either by CDM light in future or in can run from commandline so it is not needed in TaxEditor anymore.
Should be discussed with Walter.
If we keep it we should handle it like other long running export tasks.
