fix(Reorder): Fix EditableFormField to fallback to current page editing permissions when reordering with GridFieldOrderableRows component.
fix(Reorder): Check if record exists before calling 'hasExtension' check.
Fixes#350 and fixes#404
This change abandons validation via EditableFormField::validateField, as it bypassed too many core validation mechanisms (RequiredFields, etc).
In order to enforce consistency of editable field validation, display rules have been hard-disabled when a field is marked as required.
Since this removes functionality, I have incremented the major version number
- Page no longer reloads on new field
- Preview mode no longer errors on new field
- Sort order of field dropdown is ordered
- Default field type to Text field instead of abstract base class
- Ensure fields named 'Field' is invalidated.
