  • Hello.

    I think there is a bug in SequenceOf constructor.

    
        public SequenceOf(ByteQueue queue, Class<E> clazz) throws BACnetException {
            values = new ArrayList<E>();
            while (peekTagNumber(queue) != -1)
                values.add(read(queue, clazz));
        }
    
    

    I used ObjectProperties to add property reference for my own bacnet object.

     		add(new ObjectType(146), new PropertyIdentifier(552), GSMPersons.class, false, false, null);
    

    GSMPersons is a property, that contains SequenceOf<CharacterString> without any context id.

    When I'm trying to read this property:

    0000   00 23 54 ed 8d 5d 08 60 6e 79 44 75 08 00 45 00  .#T..].`nyDu..E.

    it reads one element of sequence ("+79261314103") and then I get an exception, because ByteQueue contains only "3F", that is closing context tag of property value in read property request. And peekTagNumber(queue) is not -1.


  • I changed constructor, now it works.

    	public SequenceOf(ByteQueue queue, Class<E> clazz) throws BACnetException {
    		values = new ArrayList<E>();
    
    		int tagNumber = -1;
    		while ((tagNumber = peekTagNumber(queue)) != -1
    				&& matchNonEndTag(queue, tagNumber))
    			values.add(read(queue, clazz));
    	}
    
    

  • Maybe the SequenceOf<CharacterString> should just have a context id?
