Actually the relationship is to-many,
Well, I guess we can discard that theory. :-)
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);
}
}
That looks fine.
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;
}
Again, that looks fine.
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.
It still sounds to me like there is some other InventoryTransDetail
object in that editing context. Have you tried printing out
ec.insertedObjects() just before calling ec.saveChanges()? Is
productSelected.editingContext() == ec?

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!
