Try FT_NONE
not BASE_NONE

Hey guys I got over the last hump. When I tried to add the payload item to
the tree as a size of 80 things blew up, but when I call a routine to
determine the number of bytes remaining (which is 80) things worked fine....
go figure. Anyway, here is what I used to get it working:
payload_size = tvb_reported_length_remaining(tvb, offset);
tvb_ensure_bytes_exist(tvb, offset, payload_size);
proto_tree_add_item(vppn_tree, hf_payload, tvb, offset, payload_size,
FALSE);
But now as you can see it tries to display all 80 bytes in the proto tree,
when I basically just wanted the payload highlighted in the packet info. Is
there an easy way to stop the display of the value? I thought just putting
BASE_NONE in the field would stop the display, but it didn't.

How about feeding the data to the data dissector?
Create a sub_tvb from the current offset to the end of the frame (assuming
the data is at the end) and hand that to the data dissector. Lots of
samples in other dissectors.
Thanx,
Jaap

everybody in the world it seems) insist that I add a final branch that
highlights the actual data packet (in this case - an 80 byte audio packet).
Everything I have tried throws a failed assertion.
