I have a writable external data source with 2 external objects:
Car__x
- VIN__c - Unique External Id (maps to VIN column in Car table)
- Plant__c - Lookup to custom object Plant
Part__x
- Car__c - External Lookup to Car (maps to CarVIN column in Part table)
- Plant__c - Lookup to custom object Plant
When a Part is inserted it shows up as a child on the Plant layout. However the external lookup field Car__c shows as blank only on the related list. If I view or edit the record the external lookup is there.
This issue does not exist in Salesforce Classic.
Is this an undocumented bug or am I doing something wrong here?!
