Attribute type for foreign keys. Supports a 'collection' property for a source collection. The collection can be the collection itself or function that returns a collection. Though arrays and objects are supported, it is recommended you use an awa.mvc.Collection Certain inputs will NOT work unless you use awa.mvc.Collection

pat_phy_id: {
    name: "Rendering Provider",
    rules: {
        required: true
    },
    collection: function(){
        return awa.clientModel.get('cli_rendering_providers');
    }
},

listValue types provide a displayMethod and will attempt to use the linked model's displayName.
