Using Archetype in Custom Section on Umbraco 7

Questions
1

I have created a Custom Section that allows for creation of new nodes of a specific doctype using an Angular view and controller.
I am rendering all of the properties for that doctype that I want to be able to update in this section using this:

<ng-form>
    <umb-property property="property" ng-repeat="property in tab.properties">
        <umb-editor model="property"></umb-editor>
    </umb-property>
    <pre></pre>
</ng-form>

All of the properties I’m using display correctly, except one which is using an Archetype datatype.
I am getting the error:

Cannot read property ‘contentTypeAlias’ of null

This is occurring on line 727 on the archetype.js file.

Is there anyway to get an Archetype property to work in a Custom Section like this?
