获取选定行的 ExtJS4 可编辑网格返回空

Question

Trying to get the selected row index (and set another field value of the record afterwards) on a grid with CellEditing plugin, but method returns an empty array. I have a listener for select event on the combobox, when that is changed I need to get the index of the edited row.

...
lazyRender: true,
listClass: 'x-combo-list-small',
listeners: {
    scope: this,
    select: function(field, value, options) {
        var selection = Ext.getCmp('lineItemsGrid').getSelectionModel().getSelection();                                            
        console.log(selection);
    }
}
...

I'm using ExtJS 4.0.2a release. I'm a newbie when it comes to ExtJS, so I might be missing something.

Here is JSFiddle file in cas you want to have a look.

Any help is greatly appreciated.

Thanks

You don't need to use the getSelection() method, you can update the record directly from the edit event.

I've updated the fiddle, and also here is the code to update the record after edit:

edit: function(editor, e, options) {
     e.record.set('light', 'Shade');
     //var selections = Ext.getCmp('lineItemsGrid').getSelectionModel().getSelection();
     //console.log(selections);
}
