Workflow definition GridField has import/export CSV actions (that don't work)

[robbieaverill]

In SS4 the default GridField on the "Workflows" CMS area has an import and export CSV action:

The export action works, but the import action doesn't.

When compared with a SS3 version these actions are not available, so I suspect they shouldn't be there in SS4 either:

The GridField items should have their own export action, rather than the CSV for the whole GridField:

Ok, I've got the inline export buttons working. The import functionality has two problems:

• We can't change "import CSV" at the moment, because it's not adjustable in core. We could extend the class instead.
• The bulk loader for importing workflow definitions isn't actually being called after your submit the form
• Re-open the import dialog to see MIME validation failed: Could not find a MIME type for extension yml - could be from the mimevalidator module

Note that the above three points are not regressions when testing between CWP 1.x and 2.x, whereas the broken export functionality is.

I'll submit a pull request to fix the first few issues which at least re-enables export functionality, and we can address import separately.

Worth mentioning - I think that this is probably caused by a compatibility issue with the mimevalidator module in CWP
