Constant values for enumSource broken

The following schema is supposed to produce an select field with two constant values to chose from:

{
  "type": "string",
  "enumSource": [
    ["foo"],
    ["bar"]
  ]
}

However, the following error is thrown instead:

Uncaught TypeError: a.match is not a function

The error is apparently thrown in the compile method of the template engine.

We’ve managed to work around the bug by defining the constant as an enumsource as well, with just one static value as source:

"object": {
    "watch": {
        "ids": "somename.someIds"
    },
    "enumSource": [
        {
            "source": [
                {
                    "value": "None"
                }
            ],
            "title": "{{item.value}}",
            "value": "{{item.value}}"
        },
        {
            "source": "ids",
            "title": "{{item.id}}",
            "value": "{{item.id}}"
        }
    ]
}

+1 We are getting this error too, which is particularly an issue since support for the constant syntax is still in the documentation while it’s broken.
