Missing listbox selectedItems MVVM 'set' method not detected

By chance I've noticed that if you create a MVVM ZUL file that includes a listbox with a 'selectedItems' attribute defined like:

selectedItems="@bind(vm.selectedGizmos)"

... then if the related MVVM class is missing an expected 'setSelectedGizmos' method then nothing happens.

I would have expected some validation by ZUL to report the missing 'setXXXX' method
