[BUG] ChartWrapper Adding Listener for getSelection() function freezing

[Ibrahim Pala]

There is a bug while adding listener on chartname.getSelection();

Example: This function is Show/Hide Columns. And it is working on 
google.visualization.ComboChart with decument.getElementbyId
but if bind smt with ChartWrapper it freezes


<script type="text/javascript" src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load('visualization', '1', {packages: ['controls', 'charteditor']});
google.setOnLoadCallback(drawChart);


function drawChart() {
    var data = new google.visualization.DataTable();
        data.addColumn('date', 'Date'); 
        data.addColumn('number', 'series1');
        data.addColumn('number', 'series2');
        data.addRows([
          [new Date(2015, 11, 15, 1, 30), 10, 100],
          [new Date(2015, 11, 16, 2, 30), 20, 90],
          [new Date(2015, 11, 17, 3, 30), 30, 80],
          [new Date(2015, 11, 18, 4, 50), 40, 70],
          [new Date(2015, 11, 19, 13, 11), 50, 60],
          [new Date(2015, 11, 20, 23, 59), 60, 50],
        ]);


    var dash = new google.visualization.Dashboard(document.getElementById(
'dashboard'));


    var myControl1 = new google.visualization.ControlWrapper({
        controlType: 'DateRangeFilter',
        containerId: 'control_div',
        options: {
            filterColumnIndex: 0,
            ui: {
                chartOptions: {
                    height: 50,
                    width: 1280,
                    chartArea: {
                        width: '80%'
                    }
                },              
            },          
        }
    }); 


    var myChart1 = new google.visualization.ChartWrapper({
        chartType: 'ComboChart',
        containerId: 'chart_div'
    });




    function showHideSeries () {
        var sel = myChart1.getSelection();


        if (sel.length > 0) {
            if (sel[0].row === null) {
                var col = sel[0].column;
                if (columns[col] == col) {
                    columns[col] = {
                        label: data.getColumnLabel(col),
                        type: data.getColumnType(col),
                        calc: function () {
                            return null;
                        }
                    };
                    series[col - 1].color = '#CCCCCC';
                }
                else {
                    columns[col] = col;
                    series[col - 1].color = null;
                }


                var view = new google.visualization.DataView(data);
                view.setColumns(columns);
                myChart1.draw(view);
            }
        }
    }


    dash.bind([myControl1], [myChart1]);
    dash.draw(data);


    google.visualization.events.addListener(myChart1 , 'ready', function(){
         google.visualization.events.addListener(myChart1 ,'select', 
showHideSeries);
