                 throws java.lang.Exception

Create a widget from a widget descriptor. This default implementation uses reflection to find an appropriate constructor: if the widget descriptor has no properties it will look for a constructor for the descriptor's widget class that takes a UiObject. Otherwise it will look for one that takes UiObject, WidgetDescriptor, and WidgetFactory.
