	 * does nothing if the container resources already exist.
	 * <p>
	 * In normal usage, this method is invoked after the user has pressed Finish
	 * on the wizard; the enablement of the Finish button implies that all
	 * controls on this page currently contain valid values.
	 * </p>

	 * Note that this page caches the new folder once it has been successfully
	 * created; subsequent invocations of this method will answer the same
	 * folder resource without attempting to create it again.
