Ext JS component cannot display json data read from proxy

Not entirely sure why, but when using ajax proxies, specifying the URL is not enough, the data won’t be displayed on lists/panels.

A reader must also be defined in the proxy, otherwise the data will not be read correctly

proxy: {
type: ‘ajax’,
url: ‘data.json’,
reader:{
type:’json’,
rootProperty: ‘DATA’
}

}

Make sure that

• the source data is working, test using Fiddler/POSTMan/etc
• The model’s fields match the fields in json data, case-sensitive.
• A reader is configured in the proxy
• rootProperty is set correctly and match the json data, case-sensitive.
