How to insert a new record to a store

[Speedy]

Hi there,

i defined a store

Ext.define( 'App.store.general.MyStore' , {
    extend: 'Ext.data.Store',

    autoLoad: true, fields: ['display', 'value'], name: 'myStore', storeId: 'myStore',
    proxy: {
        type: 'ajax', url:'myUrl',
        extraParams: { ... },
        reader: {
            type: 'json', root: 'data', idProperty: 'value'
        }
    }
});

in my Application I create this store via

var store = Ext.create( 'App.store.general.MyStore', {} );

so far everything works fine, the store is loaded and used within a combobox.
now I want to add a new record to the store and I tried

store.add({ display: 'abc', value: '0' });

and

store.insert( 0, { display: 'abc', value: '0' });

since the data of the loaded store start their values from 1-15 I thought 0 or 16 should work but there simple happens nothing. No error, no new entry.

What am I doing wrong?


Best
