3587565 - SAC : Error after converting application to “Optimized View mode” option

• When enabling “Optimized View mode” option in Analytic Application and running the application, it raises errors :
• Script execution failed for event "currency_chart.onResultChanged"
  or Script execution failed for event "Page_1.onInitialization"
• In Console :  Cannot read properties of undefined (reading 'id') TypeError: Cannot read properties of undefined (reading 'id')

The rootcause of the issue is from the following scripting in Initialization.fcn_initialize_dropdown_div1:

var divMembers = gl_dataSource_sourceChart.getMembers("ZMFWLVL1");
for (var i = 0; i < divMembers.length; i++) {
  Drop_Area_Main_Settings_Division_Level1.addItem(divMembers[i].id, divMembers[i].description);
}
if (gl_string_toInitialise === "TRUE" || gl_string_division_1_selectedKey === "") {
  Drop_Area_Main_Settings_Division_Level1.setSelectedKey(divMembers[0].id);
  gl_dataSource_sourceChart.setDimensionFilter("ZMFWLVL1", divMembers[0].id);
}

DataSource.getMembers cannot make sure the order of members. Members order of classic mode and optimized design mode is different. 
The first member id of divMembers is "10" in the classic mode and it's "" in the optimized design experience mode.

Dropdown addItem API cannot accept an empty string as key. It means that "" is not added to Drop_Area_Main_Settings_Division_Level1 and setSelectedKey for "" cannot be selected. The script of currency_chart.onResultChanged reply on the selected key of Drop_Area_Main_Settings_Division_Level1.

The solution is to filter out the empty id of divMembers or choose predefined member for Drop_Area_Main_Settings_Division_Level1 :

Filter code:

var tempDivMembers = gl_dataSource_sourceChart.getMembers("ZMFWLVL1");
var dimMembers = ArrayUtils.create(Type.MemberInfo);
for (var j = 0; j<tempDivMembers.length; j++) {
    if (tempDivMembers[j].id) {
        dimMembers.push(tempDivMembers[j]);
    }
}
