Even if the widget is set i.e. in autoFilter=false OR selectionMode=multiple, at the creation time the widget's inputNode does not have the readonly attribute set. If the user gets the focus on the widget via tabbing over the page and then he starts typing, the input is "no-readonly" mode, allowing so the actual typing.
