Bug report

When the Chinese IME typing is used and the minLength is set in the ComboBox the items can not be properly selected using the keyboard.

Reproduction of the problem

1. Open the Dojo example - https://dojo.telerik.com/@NeliKondova/EZILudiz
2. Add and use the Chinese language
   
3. Type 'bao' and press space to convert to Chinese
4. Press Tab or Enter to select.

Current behavior

When minLength is defined the item in the ComboBox is not selected, the dataitem is not accessible in the change event handler (screencast). The item is selected as expected if the value is copy pasted (包).

Expected/desired behavior

The items should be selected when using the Chinese IME typing after filtering the data and selecting an item through the keyboard.

If you bind a ComboBox widget to a datasource containing arbitrary objects that contain a "data" field, the dropdown items will be "undefined" instead of the value of the dataTextField. I'm guessing the data field is messing up the template variable.

var formData = [
   {
      key: '1',
      description: 'CT Safety',
      formTypeCd: 'S',
      data: {foo: '', bar: ''}
   },
   {
      key: '2',
      description: 'MR Safety',
      formTypeCd: 'S',
      data: {foo: '', bar: ''}
   },
   {
      key: '3',
      description: 'Medicare > 60 Billing',
      formTypeCd: 'I',
      data: {}
   }
];

$("#forms-combobox").kendoComboBox({
   dataTextField: "description",
   dataValueField: "key",
   dataSource: formData
});

Hi,

we found a hard to reproduce bug in the combobox control. It appears infrequently while typing in the combobox input, if the combobox has grouping and the fixed header enabled. It does not seem to have functional implications to the control but it produces a javascript error.

Stacktrace:

_firstVisibleItem: function () {
    for (var t = this.element[0], n = this.content[0], i = n.scrollTop, r = e(t.children[0]).height(), o = Math.floor(i / r) || 0, a = t.children[o] || t.lastChild, s = a.offsetTop < i; a; ) if (s) {
      if (a.offsetTop + r > i || !a.nextSibling) break;
      a = a.nextSibling
    } else {
      if (a.offsetTop <= i || !a.previousSibling) break;
      a = a.previousSibling
    }
    return this._view[e(a).data('offset-index')]
  }

It seems to be a timing problem where the list is already loading again while the scroll from the item selection is not finished.

Hi,

You prob. already know this, but in Chrome attribute autocomplete should be "disabled" instead of "off" for e.g. combobox - then we don't get the auto fill.

Even thought it has no id nor name - I think it looks at the lavbel - in my case its "Name" and the combobox get a big Chrome auto fill from the address book. Setting it from "off" to "disabled" will disable both auto complete AND auto fill.

The same goes for the AJAX Combobox - will you notify that team too? Current hotfix for that is `$(".rcbInput").attr("autocomplete", "disabled");`

Thanks
