Matthew Windwer created CB-1385:
-----------------------------------
Summary: 2.1.0rc2 breaks certain plugins on iOS due to added
"null" argument using FORMAT TWO in iOSExec
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: Filip Maj
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];
