IError and data

[bo55vxr]

I have two query services, one is a Customer and the other is a Notes, both can be called independently, and each are underpinned with a respective REST service. However, if you execute a Customer query, you can additionally request their notes too, and this is accomplished with a Field Resolver.

Now, lets say the Customer service is working fine and dandy, but the Notes service is currently off-line....

Scenario 1
If I make a direct query to Notes, then an IError response is sent with the appropriate information and no data is available, even that the data property is returned to the consumer.

Scenario 2
I request a Customer which I also want Notes too ... but as Notes service is down, it wont be able to provide it... In this case, I want to respond with the Customer details, provide an empty Notes list, but need to inform the consumer that Notes is not available.

Can I do this with an IError response ... I can send back an error, but I don't seem to be able to populate the data property with the data I have.

Thanks in advance.
