ScriptTagProxy and JSONP wrapped XML response

[r4nd7263]

Is it possible to use ScriptTagProxy to handle XML data wrapped in JSONP?


Something like:

var store = new Ext.data.Store({
            model : 'MyModel',
            proxy : {
                type : 'scripttag',
                url : 'http://domain2/rest/jsonp/myModel/10000',
                reader : {
                    type : 'xml',
                    record : 'MyModel'
                }
            }
        })

The server returns (with text/javascript):

stcCallback1001('<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<MyModel><id>10231<\/id><\/MyModel>')

I tried and got this error: 'Uncaught TypeError: Cannot call method 'querySelectorAll' of null'

Not sure if I didn't return the correct data format, or ScriptTagProxy simply can't handle XML data wrapped in JSONP response. Or something else went wrong.

Why not use JSON then?

That's fine. I was wondering if ScriptTagProxy supported wrapped XML, just not yet documented.

Our web service for native Android apps are serving XML in production, so I thought to reuse it that's all. If not, we will update it to support JSON as well

If developing for iOS, and wrapping with Phonegap, you could just use Ext.Ajax and you don't have to worry about cross-domain policies.

I do the testing with Safari on a mac (only browser and only platform to be able to test in my experience). But users won't have a problem accessing the info through your app in their devices, neither you while testing on the simulator with Xcode.
