Problem with proto_tree_add_uint()

Hello everyone,

I'm currently developing a custom dissector for a custom made protocol in
my universtity, mean while i've had a problem with the displaying of some
information on the stats tree. I have 2 instructions inside a if sturucture
and one of them is always performed following is a potion of my code:


    if(Sindex){ /*verificar existencia da mensagem na TM*/

        proto_tree_add_item(sdm_tree, hf_testc, tvb, 0, 0, FALSE); /*Teste
de correspondencia*/
        proto_tree_add_uint(sdm_tree, hf_ftt_TMframe, tvb, 0, 0,
Tmsg[i].frame); /*mostra em que frame está a TM*/
        /*Processamento do tempo*/
        nstime_delta(stime, &pinfo->fd->abs_ts, &(Tmsg[i].tm_time));
        proto_tree_add_time(sdm_tree, hf_ftt_TMtime, tvb, 0,0, stime);




    }
    else{
        proto_tree_add_uint(sdm_tree, hf_ftt_error, tvb, 0, 0, 1);
        col_add_fstr(pinfo->cinfo, COL_INFO, "ERROR(1)
%s",val_to_str(1,ftt_error,"X")); /*Erro a mensagem nao está na TM*/
    }
    if(duplicate==1){
        col_add_fstr(pinfo->cinfo, COL_INFO, "ERROR(2)
%s",val_to_str(2,ftt_error,"X")); /*Erro a mensagem nao está na TM*/
        *proto_tree_add_uint(sdm_tree, hf_ftt_error, tvb, 0, 0, 2);*
        }

duplicate is a gint

the instruction *proto_tree_add_uint(sdm_tree, hf_ftt_error, tvb, 0,
0, 2);*is always performed even if the condition "duplicate==1" is
false, when the
condition is true the condition is true the two instructions are performed
as they're suposed to.

Is here something missing me?
I would apreciate your help.

Best regards,

César Gomes
