Summary: Need to pass more complex objects over the bridge
Key: CB-938
URL: https://issues.apache.org/jira/browse/CB-938
Project: Apache Cordova
Issue Type: Bug
Components: WP7
Affects Versions: 1.9.0
Reporter: Abu Obeida Bakhach

[WP7] Passing more complex objects over the bridge... Currently won't work.
Basically the DataContractJsonSerializer .NET object that we employ to parse
JSON on the native side can't parse nested objects in JSON. The DataContract
stuff is supposed to make it easy to cast the various JSON values to .NET
types. In the case of a nested object with dynamic keys, that you can't model
ahead of time, we tried using a Dictionary type on the native side. This won't
work [1].
This came up when deserializing FileTransfer upload options because they have a
nested "params" object that house dynamic &key=value URL parameters to send
with the HTTP request. Not sure if it happens in other spots.
Anywho, one potential solution is to explicitly convert nested objects such as
these to a dumber structure. In the SO thread [1] they suggest having an array
of {key:"known1",value:"foo"} pairs replace the objects.
The native side could parse that.
Another option is to use the JSON.net library [2]. MIT license. 300-ish kb .dll.
The stock System.Json namespace that is available in .NET and has better
capabilities is not available on Windows Phone.
Any other solutions/ideas/comments/thoughts?
