    Default [4.1.1] Grid removeAt error

    [4.1.1] Grid removeAt error


    The test application:
    Code:
    Ext.onReady(function() {
      Ext.create('Ext.container.Viewport', {
        layout: 'border',
        items: [
          {
            region: 'center',
            xtype: 'grid',
            id: 'grid',
            store: Ext.create('Ext.data.Store', {
              fields: [
                {name: 'id', convert: null, defaultValue: undefined},
                {name: 'title', convert: null, defaultValue: undefined}
              ]
            }),
            columns: [
              {
                text: 'ID',
                dataIndex: 'id'
              },
              {
                text: 'Title',
                dataIndex: 'title'
              }
            ]
          },
          {
            region: 'north',
            xtype: 'buttongroup',
            items: [
              {
                text: 'fill grid',
                handler: function () {
                  var grid = Ext.getCmp('grid'), store = grid.getStore();
                  for (var i = 0; i <= 99; i++)
                    store.add({id: i, title: 'title' + i});
                }
              },
              {
                text: 'del rows',
                handler: function () {
                  var grid = Ext.getCmp('grid'), store = grid.getStore();
                  //store.suspendEvents(true);
                  for (var i = 99; i >= 25; i--)
                    store.removeAt(25);
                  //store.resumeEvents();
                }
              }
            ]
          }
        ]
      });
    });
    1) click "fill grid"
    2) click "del rows"
    3) no error

    Now, uncomment "store.suspendEvents(true);" and "store.resumeEvents();"

    1) reload page
    2) click "fill grid"
    3) click "del rows"
    4) error "TypeError: records[i] is undefined"

    This is resolved in 4.2.0.

    Also, it's fairly poor practice to do this. You would be better to just suspend the events without catching them and refresh the view.
