How to instantiate DynamicForm(JsonObject)

There is a typo in the title of this question. It should be
How to instantiate DynamicForm(JavascriptObject).

I would like to know how to instantiate DynamicForm(JavascriptObject).

I have a static file address.json:

var addressjson = {
	dataPath : "address",
	items : [ {
		"type" : "text",
		"name" : "street"
	}, {
		"type" : "text",
		"name" : "unit"
	}, {
		"type" : "text",
		"name" : "city"
	}, {
		"type" : "text",
		"name" : "province"
	}, {
		"type" : "text",
		"name" : "country"
	}, {
		"type" : "text",
		"name" : "zip"
	} ]
}
eatJson(addressjson);

My code ate that and produced a JavascriptObject jso. To verify that the json was eaten correctly, I did

JSONObject json = new JSONObject(jso);

which verified it to be

{
  "dataPath":"address",
  "items":[
   {"type":"text", "name":"street"},
   {"type":"text", "name":"unit"},
   {"type":"text", "name":"city"},
   {"type":"text", "name":"province"},
   {"type":"text", "name":"country"},
   {"type":"text", "name":"zip"}
 ]
}

Which means jso is indeed a proper JavascriptObject.
Then jso was fed as an argument

form = new DynamicForm(jso);

and on attachment to a Canvas, an exception was thrown, which says something similar to
"the object returned from JSNI is not a valid js object".

My questions are
1. Is this the right json structure as an argument for the constructor

DynamicForm(JavascriptObject)

?
If not, what is the right structure of the json, which when produced as a JavascriptObject, could be used as the constructor's argument.

2. Is this constructor even meant to be used for constructing the fields of a DynamicForm? If not what is it used for and what should the structure of the JavascriptObject be?

What it is expecting is the actual javascript instantiated object, just like you would declare in SmartClient. Easiest way is look at the SmartClient examples, add a DynamicForm directly into your 'script' in your host file, then load that object i.e. isc.DynamicForm.create(...). In fact all SmartGWT widgets have a protected create() method which does this in JSNI really.
