If you want to be notified of any changes in the state of an attribute, you need to call enableAttributeNotification.

the attribute.

in the constructor of the control is also called for all changes in the attribute state.

If you previously already enabled the notification for this attribute, and specified a different listener,

then the previous listener will be replaced with the new listener, provided the latter is not <NULL/>.
