I want add subtree , a HEX value with 16bytes, but buf max is 8 bytes

Question

I asked this question on the wireshark-dev mailing list and @cmaynard solved it. YOU HAVE HERE:

I want add subtree , a HEX value with 16bytes, but buf max is 8 bytes, when I tried more not works. I tried defining Protofield like a string and it works but I want to show in HEX . Why can do it?
local f_marker = ProtoField.string("myproto.marker", "MARKER", base.HEX)
subtree = root:add(p_myproto, buf(0)) subtree:add(f_marker, buf(0,16))

Accepted Answer

The intent of sending javiguembe to this site was not to ask and answer this question but to make javiguembe aware of the site so that it might be utilized to search for answers to future questions or to ask new questions. But since the question has been asked here, I'll post the relevant part of the answer I gave on the mailing list, which apparently solved the problem:

Try declaring f_marker like so:

local f_marker = ProtoField.bytes("myproto.marker", "MARKER")
