Odd behavior with kendo multiselect

[Sean]

http://jsfiddle.net/ruchan/AgV52/1/

Problem replication:
-click "Init List" and then add new tag to the box by keyboard.
-now click fill List button [it fills "1,2,3" as selected values].
- All the values are not being selected. or sometimes only last value is selected

var list=[{label:'tag1', value:'1'},
         {label:'tag9', value:'9'},
         {label:'tag8', value:'8'},
         {label:'tag7', value:'7'},
         {label:'tag6', value:'6'},
         {label:'tag5', value:'5'},
         {label:'tag4', value:'4'},
         {label:'tag3', value:'3'},
         {label:'tag2', value:'2'}];

function fillData(tagIds){

    var tagObj = $("#addTags").data("kendoMultiSelect");
    if (tagObj == undefined) { // if not loaded
        $("#addTags").kendoMultiSelect({
            dataTextField: "label",
            dataValueField: "value",
            dataSource: list,
            value: tagIds, placeholder: "Select from list",
            change: function() {
                // change
            }
        });
    } else { // if already loaded only change the values.
        tagObj.value(tagIds);
        console.log(tagIds);
        console.log(tagObj.value());
    }
}
function fillaList(){
    var tagIds=[1,2,3];
    fillData(tagIds);
}
function clearList(){
    fillData([]);
}

note: The problem in only when you do the tag selections from keyboard. Doing it by mouse clicks shows no problem

Is this a bug or i am doing something wrong?

the problem got solved when setting value.

tagObj.dataSource.filter({});

Still it looks like a bug on part of kendo.

Hello Sean,

The described behavior is expected. Please check the value method documentation for more information.

ok. but it still it isn't clear...
doing the same thing by mouse has no problems. It only happens on keyboard.

Hello Sean,

When the end users selects items using a mouse input device, the widget's data source is not filtered. If you select items using keyboard without typing - using only UP/DOWN arrow, the widget behaves the same way as the items are selected with a mouse. Once the end user decides to filter the data source, then you will need to clear the applied filter before set value through widget's API. We do not remove data source filters in the widget value method, because it causes unexpected behavior when a remote binding is used. I hope this clarifies the case.
