Pass one parameter to lov

Question

Hi,
I need to pass a parameter for one lov and am trying to pass with the code:
In the page that calls the Lov step (vinculo = 1)
<bc4j:messageLovField
name="CodPessoaAluno"
attrName="CodPessoaAluno"
columns="10"
required="yes"
message="Informe o Nome do Aluno"
prompt="Codigo"
shortDesc="Clique no botao para escolher o Nome do Aluno"
onClick="openWindow(window,
'../../sigep/lov/LovPessoas.uix?vinculo=1',
'lovWindow',
{width:700, height:525},
true,
'dialog',
FunLovRetorno);
return false;">
</bc4j:messageLovField>
In the event of the Lov page I try to catch vinculo.
public static EventResult SgCreate( BajaContext bc, Page page, PageEvent event)
int vinculo = Integer.parseInt(event.getParameter("vinculo").toString());
String quantTrains =
"select max(nvl(rownum,0)) quant "+
"from           pe_vinculos                         a " +     
"                    ,pe_vinculo_grp_inf          b " +
"where          a.vinc_cod_vinculo          = b.vinc_cod_vinculo " +
"and               b.vigi_sta_ativo      = 'S' " +
"and           a.vinc_cod_vinculo           = " + vinculo + " " +
"order by b.vigi_num_ordem " ;
However, null arrives in vinculo. How I can catch this value?
Fernando. parameter to lov and I try pass

Hard to say; does the URL in the browser still contain "vinculo"? If you call PageEvent.getParameterNames(), do you see all (or any) of the parameters you expect?
