thank you

can chained store define using ext.define statement?

definitely yes. source config of chained store says should either store instance or id of existing store.

so code this:

ext.define('myapp.store.mychainedstore', {     extend: 'ext.data.chainedstore',      storeid: 'mychainedstore',     //source using storeid     source: 'originalstore'  });  ext.define('myapp.store.originalstore', {     extend: 'ext.data.store',      requires: [         'ext.data.field.field'     ],      storeid: 'originalstore',     data: [{         id: 1,         name: 'commodi'     }],     fields: [{         name: 'id'     }, {         name: 'name'     }] });
