Custom item not related to the packet

[Antonello Tartamo <antonellotartamo () gmail com>]

Hello everyone,
I'm trying to add a custom item which is not strictly related to the packet
but it is coming from a processing of a part of the packet.
I've used the following instructions:

                new_tvb = tvb_new_child_real_data(tvb, pt, (guint)16, 16);
                add_new_data_source(pinfo, new_tvb, "processed");

                ti = proto_tree_add_item(data_tree,
hf_mp_control_processed, new_tvb, 0, 16, ENC_NA);
                PROTO_ITEM_SET_GENERATED(ti);

hf_mp_control_processed is a set of bytes:
        { & hf_mp_control_processed ,
          { "mp control processed", "mp.control.processed",
            FT_BYTES, BASE_NONE, 0x0, 0x0,
            NULL, HFILL }
        }

The problem is that when I click on this new item into the Packet Details I
see the correct byte values, while in the Packet Bytes view these ones are
totally wrong.

For example the first byte is 0x48 but 0x68 is shown in the Packet Bytes
view.

Is there a different way to perform this operation ?

Thanks in advance
