you still need to ask for complete objectList
then only show analogOutput

	private static void getObjectList(LocalDevice localDevice, String ip, int port, int deviceId) throws Exception 
	{  
		InetSocketAddress addr = new InetSocketAddress(InetAddress.getByName(ip), port);  
		ReadPropertyRequest read = new ReadPropertyRequest(new ObjectIdentifier(ObjectType.device, deviceId), PropertyIdentifier.objectList);  
		ReadPropertyAck ack = (ReadPropertyAck) localDevice.send(addr, null, 1476, Segmentation.segmentedBoth, read);  

		System.out.println("IP: " + ip);  
		SequenceOf<ObjectIdentifier> oids = (SequenceOf<ObjectIdentifier>) ack.getValue();  
		for (ObjectIdentifier oid : oids)  
		{
			if(oid.getObjectType().intValue() == ObjectType.analogOutput.intValue())
			{
				System.out.println("    " + oid);
			}
		}
	}  

i wonder if com.serotonin.bacnet4j.type.constructed.ObjectTypesSupported should be completed by

    public boolean isGlobalGroup() {
        return getValue()[26];
    }

    public void setGlobalGroup(boolean globalGroup) {
        getValue()[26] = globalGroup;
    }
