Description

EventAdmin not injected in constructor
The creation of a DummyMetaData component is not possible, it throws a NPE , as the firing of an Event in setInitialized needs an injected instance of the EventAdmin (using @reference)
But The injection does not occur in the constructor

	protected void setInitialized() {
		this.isInitialized.set(true);
	        EventBuilder.post(getEventAdmin(), Events.AFTER_IS_INITIALIZED);
	}

getEventAdmin() returns null

Desired functionality.

So we need a better place to fire the Event Events.AFTER_IS_INITIALIZED
May be in activate() ?
