Cannot use BinaryContainer field as header_filter in server_receives_message

[harshm]

I have a message that doesn't have message fields to it. The message is a type of (ACK)acknowledgement to another message and it contains only header part of the protocol. The protocol is our company's custom protocol and contains binary fields in the header and the Binary Containers name is 'Flags'

How can I verify that the received message is my ACK message?

While doing the

'''
${msg} =     Server Receives Message      header_filter = Flags  
'''

I get the following error

File "C:\Python27\lib\contextlib.py", line 17, in __enter__
    return self.gen.next()
  File "C:\Python27\lib\site-packages\Rammbock\core.py", line 503, in _receive
    msg = node.get_message(self._get_message_template(), **configs)
  File "C:\Python27\lib\site-packages\Rammbock\networking.py", line 73, in     get_message
    return self._get_from_stream(message_template, self._message_stream,     timeout=timeout, header_filter=header_filter)
  File "C:\Python27\lib\site-packages\Rammbock\networking.py", line 76, in     _get_from_stream
    return stream.get(message_template, timeout=timeout, header_filter=header_filter)
  File "C:\Python27\lib\site-packages\Rammbock\templates\message_stream.py", line     35, in get
    if self._matches(header, header_fields, header_filter):
  File "C:\Python27\lib\site-packages\Rammbock\templates\message_stream.py", line 60, in _matches
    if header[header_filter].bytes != to_bin(fields[header_filter]):
  File "C:\Python27\lib\site-packages\Rammbock\message.py", line 38, in __getattr__
    return self[name]
  File "C:\Python27\lib\site-packages\Rammbock\message.py", line 35, in __getitem__
return self._fields[str(name)]
KeyError: 'bytes'

Can the Individual fields of the Binary container be used as header filters?

Hi, could you provide a simple example in robot syntax, that shows the problem? That would simplify testing this a lot.
