Adding a default value to selects

[stramel]

I am creating a month select and need a default value of 'MONTH' which should be invalid. I have tried setting the model to a value that is declared in the titleMap but not the enum. Validation works as expected but I can't get a default value to show in the select. Is there something I am missing?

// Schema
scope.schema = {
  type: 'object',
  title: 'Payment Information',
  required: [
    'expirationDate'
  ],
  properties: {
    expirationDate: {
      title: 'Expiration Date',
      type: 'object',
      properties: {
        month: {
          title: 'Month',
          type: 'string',
          enum: monthsOfYear // Array of valid Months
        },
        year: {
          title: 'Year',
          type: 'string',
          enum: getValidCcYears() // Array of valid Years
        }
      }
    }

// Form
scope.form = [
  {
    key: 'expirationDate',
    notitle: true,
    items: [
      {
        key: 'expirationDate.month',
        type: 'select',
        titleMap: createTitleMap('MONTH', monthsOfYear), // Prepends 'MONTH'
        validationMessage: expirationMonthValidationMessages
      }, {
        key: 'expirationDate.year',
        type: 'select',
        titleMap: createTitleMap('YEAR', getValidCcYears()), // Prepends 'YEAR'
        validationMessage: expirationYearValidaitonMessages
      }
    ]
  }

// Model
scope.model = {
  expirationDate: {
    month: '?', // '?' is the key associated to the defaults
    year: '?' // '?' is the key associated to the defaults
  }
};

I have tried your code, I had to make some adjustments to get the test running but it seems to work. Maybe you createTitleMap function works differently?
Here is the code that works for me:

var monthsOfYear = ["Jan", "Feb"];
var years = ['2003', '2004'];
$scope.schema = {
    type: 'object',
    title: 'Payment Information',
    required: [
      'expirationDate'
    ],
    properties: {
      expirationDate: {
        title: 'Expiration Date',
        type: 'object',
        properties: {
          month: {
            title: 'Month',
            type: 'string',
            enum: monthsOfYear // Array of valid Months
          },
          year: {
            title: 'Year',
            type: 'string',
            enum: years // Array of valid Years
          }
        }
      }
    }
};
var createTitleMap = function(x, arr)
{
    var result = [];
    result.push({name: x, value:"?"});
    for(var i = 0; i < arr.length; i++)
        result.push({name: arr[i], value:arr[i]});
    return result;
};
$scope.form = [
{
  key: 'expirationDate',
  notitle: true,
  items: [
    {
      key: 'expirationDate.month',
      type: 'select',
      titleMap: createTitleMap('MONTH', monthsOfYear), // Prepends 'MONTH'
    }, {
      key: 'expirationDate.year',
      type: 'select',
      titleMap: createTitleMap('YEAR', years), // Prepends 'YEAR'
    }
  ]
}
];
$scope.model = {
    expirationDate: {
        month: '?', // '?' is the key associated to the defaults
        year: '?' // '?' is the key associated to the defaults
    }
};

I'm going to close this issue. I feel like it is probably user error lol
