Hi Mario,

Thank you for reporting the problem.

The latest build failed to compile one of the JavaScript files correctly, hence the exception. There are no changes to the source code itself, but we will need to run another build to fix the issue. This will likely be resolved in the next release once we run the build again.


As a workaround, we found that you can add the following script to the page, right after the ScriptManager declaration and it will make it work again:

    kendo.observable = function (object) {
        var observableObject = kendo.data.ObservableObject;

        if (!(object instanceof observableObject)) {
            object = new observableObject(object);
        return object;
Please excuse us of any inconvenience this may have caused.
