Problems connecting dynamically created contract

o0ragman0o

I have a Factory that creates Gizmo contracts...

contract Gizmo
{
	int public val;
	function Gizmo(int v) {
		val = v;
	}
}

contract Factory
{
	Gizmo public gizmoAddr;
	function Create(int _value) returns (Gizmo) {
		gizmoAddr = new Gizmo(_value);
		return gizmoAddr;
	}
	function getGizmoVal() constant returns (int) {
		return gizmoAddr.val();
	}
}

The gizmo creates fine and I can get a Gizmo.val returned through Factory.getGizmoVal().
However I can't hook into the Gizmo Instance itself in JS:

var gizmoABI = [{"constant":true, "inputs":[], "name":"val", "outputs":[{"name":"", "type":"int256"}], "type":"function"},
				{"constant":true, "inputs":[], "name":"Val", "outputs":[{"name":"",	"type":"int256"}], "type":"function"},
				{"inputs":[{"name":"v",	"type":"int256"}], "type":"constructor"}],
	gizmoAddr,
	gizmoInst,
	gizmo = web3.eth.contract(gizmoABI);

function create() {
	var val = document.getElementById('key').value;
	gizmoAddr = contracts['Factory'].contract.Create(val,{from: web3.eth.accounts[0],gas:200000});
	gizmoInst = gizmo.at(gizmoAddr);
}

The gizmoAddr that is returned to JS is different from Factory.gizmoAddr which appears to be the correct one. However, trying gizmoInst = gizmo.at(gizmoAddr); in the console fails with

> gizmoInst = gizmo.at(gizmoAddr);	
Error: INVALID_PARAMS: Invalid method parameters (invalid name and/or type) recognised

Scratch that.....I can't connect to any contracts in Mix using:

instance = web3.eth.contract(abi).at(address)
Error: INVALID_PARAMS: Invalid method parameters (invalid name and/or type) recognised

as described in the web.js docs
