Hi Jonas, When you use the ident="def"/"ref" technique in JiBX it expects you to have the definition for each reference present in your document. In your case, you're just defining the account id values (not referencing them) and just referencing the customer id values (not defining them). There's really no reason to use ident in this case, and if you instead just remove the ident attributes and treat the id values as simple strings you should get what you want.
