Wrong name in named utility?

Shouldn't be collective.z3cform.datagridfield.row.DictRow? The IFieldExportImportHandler expects the classpath, it is used when adding a new field TTW to reprocess the DGF entry in the modeleditor: https://github.com/plone/plone.supermodel/blob/bd94c73a2d4fa3690be5eb91063509b48d681425/plone/supermodel/exportimport.py#L227

When using the model editor to add a List field with a DGF widget (value_type and schema tags), the value_type and schema tags disappear because supermodel query with collective.z3cform.datagridfield.row.DictRow.

Absolutely right. Fixed that here: https://github.com/collective/collective.z3cform.datagridfield/pull/187/commits/5fe99f84f399bcf2643fc9a2f77dbdfa7ff0d2b2 and added a working example here https://github.com/collective/collective.z3cform.datagridfield/blob/834a14b27444ae1c38cff2ba221c7e602ad24acc/src/collective/z3cform/datagridfield/demo/dgftest.xml

fixed in https://github.com/collective/collective.z3cform.datagridfield/pull/187

@petschki @yurj The fix appears to break existing TTW content types. Even accessing the model editor directly or attempting to export the schema is now broken.

Sorry for the noise, the existing schema can be fixed using portal_types in the ZMI.

but maybe an upgrade step could help? Or at least a release note that helps in fixing it?
