If you check out the JsonStore docs: http://ift.tt/1k2M84l

There is this example below which suggests a json reader can use an 'idProperty' config option. I know Model's use that, but I can't find anything about a reader using it. Does anything other than a Model use the idProperty?

Also I noticed the 'root' config option for the reader is used but the docs for the reader say to use 'rootProperty', which I assume is the recommended config property to use?



Code:



var store = new Ext.data.JsonStore({
    // store configs
    storeId: 'myStore',


    proxy: {
        type: 'ajax',
        url: 'get-images.php',
        reader: {
            type: 'json',
            root: 'images',
            idProperty: 'name'       <--------- 
        }
    },


    //alternatively, a Ext.data.Model name can be given (see Ext.data.Store for an example)
    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
});

Thanks!
