    <p>I am trying to get data from web services from my app to load a list and to load more on scroll using pull refresh &amp; ListPaging plugins. I tried this with flickr API and it works fine, but problem comes when I try to access our own services because they expect "Authorization" header with Base64 encoded data and "Accept" header to decide format of response. </p> <p>This is how I have defined my store:</p> <pre><code>Ext.define('myshop.store.CatalogListStore',{ extend:'Ext.data.Store', requires: [ 'myshop.model.CatalogListItem' ], config:{ model:'myshop.model.CatalogListItem', autoLoad :true, proxy: { type: 'jsonp', url: 'http://192.168.23.89:7003/xxx-service/test/catalog/list', useDefaultXhrHeader : false, withCredentials:true, method : 'GET', headers: { 'Accept': 'application/json', 'Authorization': 'Basic YX5iOmM=' }, extraParams: { format : 'json', pagesize : 10 }, reader: { type: 'json', rootProperty: 'categories.data' } } } } </code></pre> <p>This is what I see in Chrome's network console:</p> <pre><code>Request URL:http://192.168.23.89:7003/xxx-service/test/catalog/list?_dc=1354529083930&amp;format=json&amp;pagesize=10&amp;page=1&amp;start=0&amp;limit=25&amp;callback=Ext.data.JsonP.callback2 Request Method:GET Status Code:403 Forbidden **Request Headers** Accept:*/* Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3 Accept-Encoding:gzip,deflate,sdch Accept-Language:en-US,en;q=0.8 Connection:keep-alive Host:192.168.23.89:7003 Referer:http://localhost/myshop/ User-Agent:Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/536.11 (KHTML, like Gecko) Ubuntu/12.04 Chromium/20.0.1132.47 Chrome/20.0.1132.47 Safari/536.11 **Query String Parameters** _dc:1354529083930 format:json pagesize:10 page:1 start:0 limit:25 callback:Ext.data.JsonP.callback2 Response Headersview source Content-Length:0 Content-Type:text/xml Date:Mon, 03 Dec 2012 10:04:40 GMT Server:Apache-Coyote/1.1 </code></pre> <p>If I use Poster to access these services with Authorization header I am able to see response but since Headers are not passed in request I am getting "403 forbidden" status.</p> <p>If I use headers like this it works :</p> <pre><code>Ext.Ajax.request({ url: 'resources/data/templates.json', headers: { 'Accept': 'application/json', 'Authorization': 'Basic T3JkZXJSZWxlYXNlUmVmcmVzaGVyfk9yZGVyUmVsZWFzZVJlZnJlc2hlcjpPcmRlclJlbGVhc2VSZWZyZXNoZXI=' }, success: function(rsp){ } }); </code></pre> <p>but I cannot do this because I want to use listPaging plugin.</p>

    1. COheaders is apparently only available for Ajax requests and proxies but not JSONP.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
