Problem with JSONP proxy

[LukeSkywalkman]

Hi,

Im having problem with load data from json file placed on other server.
Here's my code:

Ext.define('Tasty.store.Categories', 
{    extend: 'Ext.data.Store',    
requires:['Ext.data.proxy.JsonP'],    
config: {        
model:'Tasty.model.Categories',       
 autoLoad: true,       
 proxy:{           
 type:'scripttag',            
url:'http://www.upmenu.pl/api/v1/menu/productGroups/7/9/f42286f7-df2d-11e1-a35c-00163edcb8a0', 
          reader:{               
 type:'json',            
},            
callbackKey:'callback',        
}   
 }}); 

model:

Ext.define('Tasty.model.Categories', {    
extend: 'Ext.data.Model',        
config: {        
fields: [            
{name: 'name', type: 'auto'},            
{name: 'id', type: 'auto'},            
{name: 'desription', type: 'string'},            
{name: 'iconUrl', type: 'auto'},           
 {name: 'imageUrl', type:  'auto'},            
{name: 'types', type:  'auto'},            
{name: 'products', type:  'auto'}        ]    
}}); 

and response from server:

[{"id":"2d99a361-df39-11e1-a35c-00163edcb8a0","name":"Pizza","description":"do wszystkich pizzy na wynos dodajemy sosy: pomidorowy i czosnkowy","types":[],"iconUrl":null,"imageUrl":null,"products":[]},{"id":"dcb21ee4-df98-11e1-a35c-00163edcb8a0","name":"Dodatki do pizzy","description":"","types":[],"iconUrl":null,"imageUrl":null,"products":[]},{"id":"c410851d-df96-11e1-a35c-00163edcb8a0","name":"Dania obiadowe","description":"wszystkie zestawy serwowane z kompotem dnia","types":[],"iconUrl":null,"imageUrl":null,"products":[]},{"id":"6a32f65e-df99-11e1-a35c-00163edcb8a0","name":"Dodatki obiadowe","description":"","types":[],"iconUrl":null,"imageUrl":null,"products":[]},{"id":"6ee1bb73-df98-11e1-a35c-00163edcb8a0","name":"Napoje","description":"","types":[],"iconUrl":null,"imageUrl":null,"products":[]}] 

and when i changed proxy type to ajax and read json from local file it loaded it properly...

Anyone knows solution?

The server side needs to support your jsonp request. If you do not control the server side, you will need to reference the server-side API for jsonp requests or figure it out by trial and error. I believe the sencha touch 2 twitter example provides a good client-side reference implementation for jsonp. You may want to take a look at that example.
