Allow for non-observable data source from MVVM dropdown
Often I have a MVVM model with an enumerable field which is used to populate dropdowns.

I know this data won't change, so I'd like to avoid wrapping into ObservableArray to increase performance, and I name this field, e.g., "_data" (starting with "_" to prevent wrapping).

But kendo throws an error in this case when dropdown's value is changed, 'cause it calls internally "get" method on change, which belongs to Observable.

Can you provide some more details, example code or dojo example to showcase the setup so that we can properly evaluate the case? 

With a recent version of Kendo, there should be no errors using a "_data" field in an Observable object. Plus, if you are using Kendo DropDownList you can use the setDataSource method to bind it to any data outside of an Observable object so that it is not wrapper with observable properties.
