H:SelectOneMenu não retorna valor do selectItem

Boa Tarde De novo

Estou com outro problema, tenho um h:SelectOneMenu, com 3 opções, a opção 1 ele retornar o codigo 1, a opçao 2 o codigo 2 e a opçao 3 o codigo 3, quando ele vai pro MB ele está passando o valor para varável, mas se eu escolho a opção 2 ou 3, ele da um nullpointer.

parte do selectOneMenu e parte do MB

ManagedBean


public void carregarListas() {
		
		if(codTipoTermo==1 || (termo.getTipoTermo() != null && termo.getTipoTermo().getTipoTermoCodigo()==1)){
			arrayListBemApreendidos = (ArrayList<TipoBemApreendido>) new TipoBemApreendidoDao().listaTudo();
		}else{
			if(codTipoTermo==2 || (termo.getTipoTermo() != null && termo.getTipoTermo().getTipoTermoCodigo()==2)) {
				arrayListTipoNatureza = (ArrayList<TipoNatureza>) new TipoNaturezaDao().listaTudo();
			}
		}

				
	}

Eu entro no modo DEBUG, ele mostra q a variavel ta com o CODTIPOTERMO==2 ele nao entra no primeiro IF, ou seja, ele faz a comparaçao, mas logo depois da comparacao ele da um NULLPOINTER.

o erro é o seguinte:

Acho que o problema é dentro do método carregarListas. Provavelmente termo é nulo.
