Following-up on my thread Wrong Widget/Field conversion in datagrid while simplifying my question to: what causes this traceback?
Traceback (innermost last):

AttributeError: 'datetime.date' object has no attribute 'split'
I am attempting to display a date in a collective.z3cform.datagridfield. My object contains a date, z3c.form.object then fails, using <DateWidget 'invoic_in_date'>
as the widget and <DateWidgetConverter converts from Date to DateWidget>
as the converter when using plone.app.z3cform.converters.
Here, toFieldValue()
expects a string and intends to return a date - which obviously fails...
I do not understand the innards of the DataGrid field well enough to find the cause of this issue. How to fix?
Also, the same type of error occurs with a schema.Choice field. Here plone.app.z3cform.converters expects the object converter to pass a list rather than a string. I have a <SelectWidget 'document_reference_type'>
and z3c.form.object is using <SequenceDataConverter converts from Choice to SelectWidget>
