Strange Url in JSONP Proxy

[wiggerl3000]

Hey Guys,

in my App i want to Retriever Data via json an my code looks like this

xtype: 'list',                    
              title: 'Tabelle',
              iconCls: 'star',
               itemTpl: '{Platz} {Team_Kurzname} {PlusTore}:{MinusTore} {PlusPunkte}:{MinusPunkte}',
                    store: {
                        fields: ['Platz', 'Team_Kurzname', 'PlusTore', 'MinusTore', 'PlusPunkte', 'MinusPunkte'],
                        proxy: {
                            type: 'jsonp',
                            limitParam: null,
                            url : 'myurl.com',
                            extraParams: {
                                liganummer: '20011800',
                                jn: '1',
                            },
                            reader: {
                                type: 'json',
                                root: 'Tabelle'
                            },
                        },
                        autoLoad: true
                    }

this is an Item in my TabBar.

now if i look into the URL, that is fired out by Sencha it looks like this:

http://myURL.com/tabellen/xyz.php?_dc=1318623514175&liganummer=20011800&jn=1&page=1&start=0&callback=Ext.data.JsonP.callback2

So it fires me out an error!!!

Is that a Bug that the callback variable is like that????

What is the error it is giving you? When I first wrote it we would just put a temporary function in the global scope but it looks like someone has changed it...

[wiggerl3000]

Hi,

this is the error thrown out:

ReferenceError: Can't find variable: ExtdataJsonPcallback2

but this error is referred to my PHP document.

What i want to know is why is the Callback variable set to:

callback=Ext.data.JsonP.callback2

I think this is the Problem

Edit:

I`ve looked into the JSON, that is thrown back from my Server an put the result in an JSON-Validater, and also here is the ExtdataJsonPcallback2variable in front of the JSON an so this is invalid.

Thanks

Right - this looks like your bug instead of ours (unless I'm misunderstanding something)

[wiggerl3000]

So made a review of my Code but didn`t find the reason.

In ST1 I do exactly the same call and it works fine ??? Strange

Also I don`t know why all errors are thrown out twice???

I do only this one JsonP call but there are two errors

ReferenceError: Can't find variable: ExtdataJsonPcallback1

ReferenceError: Can't find variable: ExtdataJsonPcallback2

Is that a bug or did I make a coding error??

I did not change the code above

[edspencer]

I see - I thought you were saying it causes a php error... we'll investigate

Please post what data the server is returning as well.

[wiggerl3000]

Which data do you want to have the JSON returned from the server??

Edit:

I found another problem with Google Chrome Inspector.

Uncaught ReferenceError: ExtdataJsonPcallback2 is not defined(anonymous function)

If you're making a request to the server, the server will be returning something in the HTTP response, what is it?

[wiggerl3000]

So this is the complete Response Header

HTTP/1.1 200 OK
Date: Wed, 19 Oct 2011 12:54:09 GMT
Server: Apache/2.2.20
X-Powered-By: PHP/5.2.13
Connection: close
Transfer-Encoding: chunked
Content-Type: json

I think I found the problem the sencha-touch-all-debug.js sets a Breakpoint at Line 1952
and that crashes the Loading (in my opinion!!)

return function() {
            var callArgs = args || arguments;


            if (appendArgs === true) {
                callArgs = slice.call(arguments, 0);
                callArgs = callArgs.concat(args);
            }
            else if (typeof appendArgs == 'number') {
                callArgs = slice.call(arguments, 0); 
                Ext.Array.insert(callArgs, appendArgs, args);
            }


            return method.apply(scope || window, callArgs);
        };
