I'll take this on - thanks Andrew.

> Key: CB-1385
> URL: https://issues.apache.org/jira/browse/CB-1385
> Project: Apache Cordova
> Issue Type: Bug
> Components: CordovaJS, iOS
> Affects Versions: 2.1.0
> Environment: iOS
> Reporter: Matthew Windwer
> Assignee: Andrew Grieve
> Fix For: 2.1.0

>
> This was brought to my attention when the InAppPurchaseManager plugin no
> longer worked for me on 2.1.0rc2, but was working in 2.0.
> The issue happens when calling cordova.exec using "FORMAT TWO", e.g:
> cordova.exec('InAppPurchaseManager.requestProductData', productId, callback +
> '.success', callback + '.fail');
> When the arguments get to the native side there is an extra null value
> preceding the rest of the arguments. This is only a problem when the plugin
> expects the arguments to be in a certain order, like for
> InAppPurchaseManager. A workaround for InAppPurchaseManager is to increase
> the index by one for each call in the .m file (e.g. [arguments
> objectAtIndex:0] becomes [arguments objectAtIndex:1]).
> The extra null value is the callbackId, which is always going to be null
> using "FORMAT 2". The code that handles this was refactored since 2.0, which
> may be the source of the problem, in particular around line 959 of the
> current cordova.js:
> var command = [callbackId, service, action, actionArgs];
