buffered store editor grid.

we have been using version 4.1.1 , migrating 4.2.0.663. have editor grids buffered stores contain large volume of data. editor grids similar row-editing example(except uses buffered store). add functionality grid has stopped after migration , raises error

ext.error: insert operation not supported buffered store.

var rowediting = ext.create('ext.grid.plugin.rowediting', {         clickstomoveeditor: 1,         autocancel: false     }); // create grid , specify field want // use editor @ each column. var grid = ext.create('ext.grid.panel', {     store: store,     columns: [{         header: 'name',         dataindex: 'name',         flex: 1,         editor: {             // defaults textfield if no xtype supplied             allowblank: false         }     }, {         header: 'email',         dataindex: 'email',         width: 160,         editor: {             allowblank: false,             vtype: 'email'         }     }, {         xtype: 'datecolumn',         header: 'start date',         dataindex: 'start',         width: 90,         editor: {             xtype: 'datefield',             allowblank: false,             format: 'm/d/y',             minvalue: '01/01/2006',             mintext: 'cannot have start date before company existed!',             maxvalue: ext.date.format(new date(), 'm/d/y')         }     }, {         xtype: 'numbercolumn',         header: 'salary',         dataindex: 'salary',         format: '$0,0',         width: 90,         editor: {             xtype: 'numberfield',             allowblank: false,             minvalue: 1,             maxvalue: 150000         }     }, {         xtype: 'checkcolumn',         header: 'active?',         dataindex: 'active',         width: 60,         editor: {             xtype: 'checkbox',             cls: 'x-grid-checkheader-editor'         }     }],     renderto: 'editor-grid',     width: 600,     height: 400,     title: 'employee salaries',     frame: true,     tbar: [{         text: 'add employee',         iconcls: 'employee-add',         handler : function() {             rowediting.canceledit();              // create model instance             var r = ext.create('employee', {                 name: 'new guy',                 email: 'new@sencha-test.com',                 start: ext.date.cleartime(new date()),                 salary: 50000,                 active: true             });              store.insert(0, r);             rowediting.startedit(0, 0);         }     }],     plugins: [rowediting], });

please advise on approach followed.

have similar problem row editing plugin. looks problem related buffered store internals changed. solve issue can:

  1. extend row editing plugin , change way insert data. after inserting reload current page of data or so...
  2. switch using buffered store using bufferedrenderer plugin grid. quick overview of plugin can find here: bufferedrenderer
  3. do deeper research, there solution without eliminating buffered stores.

i case i'm going choose second way unless clarify changes in buffered stores in extjs 4.2...

update: appears buffered stores have limited functionalty in 4.2. , still buggy. have problem now: commit bug
