 * TGlobalClassAware class.
 *
 * This behavior registers the handlers `fxAttachClassBehavior` and `fxDetachClassBehavior`
 * of the owner to listen for dynamic changes to its class behaviors (after it is
 * instanced).
 *
 * This should only be used when the TComponent is not {@see \Prado\TComponent::listen()}ing
 * or the handlers will be double added.  Listening is turned on automatically with
 * {@see \Prado\TComponent::getAutoGlobalListen()} (returning true) for select classes.
 *
 * Without this behavior (or listen), an instanced TComponent will not update its
 * class behaviors when there is a change in the global class behaviors.

It seems like $this->getPriority() can also be of type double; however, parameter $priority of Prado\TComponent::attachEventHandler() does only seem to accept Prado\numeric|null, maybe add an additional type check?
