Thank you. So if I understand it correctly I could use:
defer : function() {
qx.ui.form.DateField.getDefaultDateFormatter = function() {// ...}
},
in my subclass to overwrite static methods of the superclass. Is this a
valid approach for overwriting static members? Could we add it to the
documentation under polymorphism? If so I rather overwrite the
defaultDateFormatter than removing the listener. From my POV it doesn't
not make sense to add the listener in the superclass constructor and
remove it again in the subclass constructor, it seems to create
unnecessary overhead.
Regards,
Martijn
