Thank you for pointing us to this issue. I have tested it and found that it is related to dxToolbar directly. So, I have passed this problem to our developers for further research. Please bear with us.

My pleasure. : ) When there is a fix way, please tell me. Thx.

Hello Yang,
We've just published a hotfix. Please find it in the following ticket:
dxActionSheet renders duplicated items when initially displayed

Thx a lot~! I will try it now~!

It seems there is something error in this hotfix. There is an extra blank sheet in my app. Here is the shotcut. What can I do~?

And here is the code :
AppNamespace.view_home = function(){
            showActionSheet = function () {
                homeViewModel.actionSheetVisible(true);
            };
        var homeViewModel = {
            actionSheetVisible :ko.observable(false),
            actionSheetData : ko.observable([{text:"Logout", clickAction: function(){ logout();}}]),
            homeToolbarItems:[
                { location: 'right', widget: 'button', options: { icon: 'preferences', clickAction: showActionSheet }},
                { location: 'center', text: '人员列表' }
            ]
        };
        return homeViewModel;
};
