Hello Chuck,

I was finally able to print the contents of ec.insertedObjects(), and here is what I've found:

Complete Transaction
Item: {values = {poreceptiondetail = "null"; lot = 421; prefix = 6; supplierlot = <com.webobjects.foundation.NSKeyValueCoding$Null>; transsign = 1; lineitem = 1; inventorytransheader = "<InventoryTransHeader 14b1008 <EOTemporaryGlobalID: 0 0 -64 -88 10 3 0 0 7 -26 -51 0 0 0 1 12 -39 19 64 63 103 116 -44 -5>>"; qty = 10000; secondarylot = "1691"; location = "<Location 1852c7f _EOIntegralKeyGlobalID[Location (java.lang.Integer)4]>"; product = "<Product aff1e8 _EOIntegralKeyGlobalID[Product (java.lang.Integer)212]>"; }; this = "<InventoryTransDetail ce3b01 <EOTemporaryGlobalID: 0 0 -64 -88 10 3 0 0 7 -26 -50 0 0 0 1 12 -39 19 64 63 103 116 -44 -5>>"; }

Registered objects where product is null
Item: {values = {poreceptiondetail = "null"; lot = 0; prefix = 0; supplierlot = <com.webobjects.foundation.NSKeyValueCoding$Null>; transsign = 1; lineitem = 6; inventorytransheader = "null"; qty = 7000; secondarylot = "528"; location = "null"; product = "null"; }; this = "<InventoryTransDetail 447a24 <EOTemporaryGlobalID: 0 0 -64 -88 10 3 0 0 7 -26 -45 0 0 0 1 12 -39 19 64 63 103 116 -44 -5>>"; }


The first part(Complete Transaction) is the contents of transaction.inventorytransdetails(), and the second one is the contents of ec.registeredObjects() where product is null. As you can see the object where product is null is not part of transaction.inventorytransdetails(). Another interesting thing is that all to-one relationships are set to null, I don't have any idea of how this could have happened. In theory all objects in transaction. inventorytransdetails() should be in ec.registeredObjects().

I'll appreciate any help. Please, HELP ME!

Thanks in advanced.

Cheers.

Thank you Chuck,

I'll check what I have in the editing context before saving changes, I'm 100% sure that productSelected.editingContext() == ec.
I just have to wait until the error appears again, because actually the error only appears in deployment and not all the time, annoying right? :-)

OK, that is a different problem. That sounds like a concurrency issue. Are you creating your own editing contexts? Are you locking them properly? Are you creating additional threads in your code?

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(transactionDet ail, "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!
