Re: problem in protocol item tree header field display

Further investigation is showing me that the following are the values in
hfinfo:
1. hfinfo->flags = 1, indicating that it is HIDDEN.
I have no where in my declarations set hf_ns_nicno to be HIDDEN. Is that the
default setting or have I not set any flag elsewhere to make it visible?

2. hfinfo->ref_count = 0, making TRY_TO_FAKE_THIS_ITEM macro return without
setting value in proto_tree_add_uint(...)
When is the ref_count incremented?

thanks,
Ravi.
