Actually the relationship is to-many, here is the relationship in InventoryTransHeader
{
deleteRule = EODeleteRuleCascade;
destination = InventoryTransDetail;
isToMany = Y;
joinSemantic = EOInnerJoin;
joins = ({destinationAttribute = transid; sourceAttribute = transid; });
name = inventorytransdetails;
},
I also have the relationship in the other side, here it is:
{
destination = InventoryTransHeader;
isToMany = N;
joinSemantic = EOInnerJoin;
joins = ({destinationAttribute = transid; sourceAttribute = transid; });
name = inventorytransheader;
},
Here is the code that adds details to the header:
public void addItem() {
boolean addItemFailed = false;
if (productSelected == null) {
errors.takeValueForKey("Product is required", "product");
addItemFailed = true;
}
if (locationSelected == null) {
errors.takeValueForKey("Location is required", "location");
addItemFailed = true;
}
if (quantity == null) {
errors.takeValueForKey("Qty is required", "quantity");
addItemFailed = true;
} else if (quantity.doubleValue() <= 0) {
errors.takeValueForKey("Qty must be greater than 0", "quantity");
addItemFailed = true;
}
if (!addItemFailed) {
InventoryTransDetail transactionDetail = new InventoryTransDetail();
ec.insertObject(transactionDetail);
transaction.addObjectToBothSidesOfRelationshipWithKey(transactionDetail, "inventorytransdetails");
transactionDetail.setTranssign(Constant.ONE);
transactionDetail.setProduct(productSelected);
transactionDetail.setLocation(locationSelected);
transactionDetail.setSecondarylot(secondaryLot);
transactionDetail.setQty(quantity);
}
}
Here is the code that throws the validation exception, this validateXXX are in the class InventoryTransDetail:
public Product validateProduct(Product newValue) throws NSValidation.ValidationException {
if (newValue == null) {
throw new NSValidation.ValidationException("Product is required");
}
return newValue;
}
I hope you can help me, I'll really appreciate any help with this, I have been struggling with this error for 6 months more less.
Thank you

You probably have Propagate Primary Key set on this relationship. If the relationship is to-one and Propagate Primary Key is set, EOF will automatically create the object that is the destination of the relationship. You then create it again in your code, but the object that EOF created is still in the editing context, will all null values.

I'm using two tables(master-detail), the master is inserted in the EC when the component is loaded, then you can add details, the details are only created and inserted in the EC if the variables holding the values pass some validations(same validations are implemented in validateXXX methods in EO class), one of the validations is the one that is being thrown in saveChanges(). I've no idea of what I'm doing wrong. If you need a copy of the code and the component please let me now. I'll appreciate any help.
Thanks in advanced!
