For a custom node definition like this

```auto
<script type="text/javascript">
    RED.nodes.registerType('hello_world',{
        category: 'function',
        color: '#a6bbcf',
        defaults: {
            single: {value: "single"},
            multiple: {value: [1, 2, 3, 4]}
        },
        inputs: 2,
....

```

Will the default value for the argument _ **multiple** _ work?

If not, what's the standard way to supply vector data to nodes?

Have you tried it? Does it not work?
