Tenho um select list que eu preencho ele com um mapa, mas estou recebendo nullpointer e não sei onde.

Utilizo MyFaces 1.1, JSF 1.1

Alguém já teve esse problema?

[thiago.correa]

minha sugestão?!

br.com.x.teste.web.SecurityFilter.doFilter(SecurityFilter.java:72)

Veja se:
1- o teu Map está vazio
2- se você está executando alguma operação sobre um objeto vazio ou se o atributo está vazio

[thiago.correa]

Agora que eu percebi, ou você utiliza o MyFaces ou utiliza a implementalção da Sun
