I've tried changing Invoice method from setInvoiceStatusRelationship(InvoiceStatus value) to setInvoiceStatus(InvoiceStatus value)
Now setInvoiceStatus in Invoice does get exceuted, however I am not able to call super.setInvoiceStatusRelationship(value) because they start calling each other!! That's because setInvoiceStatusRelationship(value) calls addObjectToBothSidesOfRelationship(...) which in turn calls setInvoiceStatus(value).
You need to get into how WO's key value coding works. Check out the documentation for EOCustomObject, specifically these methods:
addObjectToBothSidesOfRelationship takeValueForKey takeStoredValueForKey
As for your problem, from what I understand you are trying to achieve, you should override setInvoiceStatus(value) in your Invoice class to do the extra work. Your method should look like this:
public void setInvoiceStatus(InvoiceStatus value) { if(value != invoiceStatus()) { System.out.println("updating invoice status date"); this.setInvoiceStatusDate(new NSTimestamp()); takeStoredValueForKey(value, INVOICE_STATUS_KEY); } }
You calling code should however use setInvoiceStatusRelationship(...) to reap it's benefits, which will in turn call your setInvoiceStatus(...) method. Also note that the first line in that method only applies if the two InvoiceStatus EOs are in the same EC.
