Extending Kendo Window Breaks Kendowindow

I believe this is a bug / design problem in Kendo UI. The only solution for now is to replace the kendoWindow widget and update the "windowObject" function so it also returns your window subclasses:

function windowObject(element, name) {
    var contentElement = element.children(KWINDOWCONTENT);

    return contentElement.data("kendoWindow") || contentElement.data("kendoMyWindow") || contentElement.data("kendo" + name);
}

Update: As of Q2 2013 SP1 (version 2013.2.918), the code in the private function windowObject has been moved to the method _object.

This means that you can subclass kendoWindow like any other widget, however you'll still need to update kendoWindow's _object method:

/**
* update kendoWindow's _object method to return our new widget as well
*/
ui.Window.fn._object = function (element) {
    var content = element.children(KWINDOWCONTENT);

    return content.data("kendoWindow") || content.data("kendoMyWindow") || content.data("kendo" + this.options.name);
};
