Hello Hussan,

Your problem probably caused by the cidade ID cannot be null on cliente table, but the load statement are not able to load the cidade to model. You can change the cidade ID to nullable in model and re-generate code & DB for solving this problem. If you have any further inquiries, please do not hesitate to contact me again.

Best regards,
