Extension - Unable to get values in initialProperties

[jdmarlin]

            initialProperties: {

                edit: [],

                qHyperCubeDef: {

                    qInitialDataFetch: [{

                        qWidth: 5,

                        qHeight: 10

                    }],

                }

            },

            definition: {

                type: 'items',

                component: 'accordion',

                items: {

                    ref: 'edit',

                    dimensions: {

                        uses: 'dimensions',

                        min: 1,

                        max: 15,

                        items: {

                            editable: {

                                type: 'boolean',

                                label: 'Editable',

                                ref: 'edit',

                                defaultValue: false

                            }

                        }

                    },

I've got a checkbox for dimensions that I'd like to output as true/false but the `edit` key is not appearing anywhere in the extension.
