I have an instance of a Gizmo contract created by a Factory but I can't hook into it from JS.
> gizmoInst = web3.eth.contract(gizmoABI).at(gizmoAddr)
Error: INVALID_PARAMS: Invalid method parameters (invalid name and/or type) recognised
Any clues?

I can't connect to any contracts using the web3.eth.contract methods.– o0ragman0oCommented May 18, 2016 at 4:57

did you deploy it on test or private network and try to access it on main, sorry to ask this dumb question but it happened to me once ;)– euri10Commented May 18, 2016 at 6:37

I'm trying this in Mix console so it's just Mix's sealed blocks. I haven't deployed anything to the chains yet because I can't get past this issue.– o0ragman0oCommented May 18, 2016 at 7:06

The error was that I was passing a stringified ABI to web3.eth.contract(ABI) and not an array object.
if you're using Mix the access to the contract is just done using contracts["contractName"] . if you follow the tutorial here, they write a contract called Rating. the way to access it in the javascript code is the following :
var res = contracts["Rating"].contract.ratings(param);
Si I'd try to access it through contracts["Gizmo"] or whatever name you called it.

The problem is that Gizmo is dynamically created by a Factory contract and so doesn't exist in the contracts[] object. Commented May 18, 2016 at 7:37
