> I have implemented support for a default command for the TargetableActionCommand-class. Sometimes it is appropriate to have a default behavior for an action and replace this behavior with a more specific one if in example some component is showing up on the screen. With my changes the component can register its specific action command executor when it shows up on the screen and deregister it when it hides. After deregistration the TargetableActionCommand will automatically register the default command again. My implementation changes the behavior of TargetableActionCommand NOT, if no default command is set.
