oneOf enum objects, type string. Help!

[JBSopra]

I'm trying to use a select with the config below but when validating the type is requesting it is a string, is there another way to do this type of enum? we need both the name and code value on the formdata but only want the name shown in the select.

Any help would be appreciated as going in a bit of a loop with ideas!

if you want any additional information I will be happy supply it.

example:

 "supplierCode": {
      "title": "Select the name of the Utility Supplier",
      "type": "string",
      "ui:options": {
        "size": 8
      },
      "oneOf": [
        {
          "title": "Supplier 1",
          "enum": [{"name": "Supplier ", "code": "11111111111"}]
        },
        {
          "title": "Supplier 2",
          "enum": [{"name": "Supplier 2", "code": "911931111198"}]
        }]
}
