Good idea.

Below is what I did to solve the problem (a little bit different, but
based on your advice). All components created by the WOSwitchComponent
extend an AbstractComponent class. I added the following to this
class:
public void awake() {
ERXWOContext.contextDictionary().setObjectForKey(this, "KEY");
}
...
public void sleep() {
ERXWOContext.contextDictionary().removeObjectForKey("KEY");
}
In the parent project 'clearInnerComponentState' method I get the
child component (an AbstractComponent type) and call the clearState
method like this:
public void clearInnerComponentState() {
AbstractCreateComponent component =
(AbstractCreateComponent)
ERXWOContext.contextDictionary().objectForKey("KEY");
if (component != null) {
component.clearState();
}
}
Now, if I have to clear the state of a component, it is just a matter
of overriding the clearState method.
Cheers,
Henrique
