JSONP Proxy generates wrong URL and ignores JSON Writer

[bytekast]

I have the proxy defined in the model instead of the store...

Ext.define('Contact', {
    extend: 'Ext.data.Model',
    fields: ['id', 'name', 'email', 'message'],
    proxy: {
        type: 'jsonp',
        url : 'contact/jsonp',
    callbackKey: 'callback',
    reader: {
            type: 'json',
        root: 'contact'
        },
    writer: {
            type: 'json'
        }
    }
});

When I am executing a model.save(), the http request received by the server is not a JSON format and the first request parameter is ignored because of the "records=" in the URL. Is this a bug or am I missing something?

http://localhost:8080/myapp/contact/...1320958562852&records=id=34&name=Test Name&email=test%40email.com&message=test&callback=Ext.data.JsonP.callback2

Thanks.

Are you aware of the difference between an Ajax Proxy and JsonP?

Take a look at the example on top of the page:
http://docs.sencha.com/touch/2-0/#!/...ta.proxy.JsonP

Yes i am aware of the difference. But this still does not explain the fact that the request parameters are not encoded in the JSON format when a JSON writer is specified.

Also, the server code loses access to one of the request parameters because of this fragment in the url: "records=id=34". This means a records parameter with a value of id is stored in the request instead of the parameter id having a value of 34....

Thanks

The problem is is that the method is going to be GET so the params will be appended onto the URL. Working with the POST method, you can transfer a JSON string in the POST body but JSONP will always be GET.
