so I've got the following attach code

Nrecord.attach({
    "record":{
        "type":"contact",
        "id":32602
    },
    "to":{
        "type":"customer",
        "id":32603
    },
    "attributes":{
        "role":-10
    }
});

it is attaching the contact to the customer, but the role is blank on the customer record. No errors are being reported. I've double checked that

-10

is the IID for

Primary Contact

, but can't figure out why it's not attaching with the correct role

you can only have 1 primary contact

I understand that. The customer record in question does not have a primary contact. I tried setting the CONTACT.company field, to the CUSTOMER, and while that attaches it automatically, it still does not set the role to

Primary Contact

thats pretty much it, you have the contact customer and the correct attribute

I thought it was right, but for some reason role isn't being set. Was making sure I wasn't missing something stupid.
