Ok, esses são os métodos “preencherTabela” e “jTableListarUsuariosCadastradosMouseClicked”
public void preencherTabela(String sql){
ArrayList dados = new ArrayList();
String[] colunas = new String[] {"Id","Usuario","Tipo","Senha"};
conex.conectarPostgre();
conex.executarSql(sql);
try {
conex.rs.first();
do{
dados.add(new Object[]{conex.rs.getInt("codigo_usuario"),conex.rs.getString("nome_usuario"), conex.rs.getString("tipo_usuario"), conex.rs.getString("senha_usuario")});
}while(conex.rs.next());
} catch (SQLException ex) {
JOptionPane.showMessageDialog(rootPane, "Busco por outro Usuário para preencher Tabela! " + ex);
}
ModeloTabela modelousuario = new ModeloTabela(dados, colunas);
jTableListarUsuariosCadastrados.setModel(modelousuario);

conex.desconectar();
}

Essa é minha tela do usuário.
O MEU PROBLEMA é que quando eu tento clicar em algum nome nessa tabela, ela me retorna esse erro. Já tentei de várias maneiras resolver, mas nada…
Alguém pra me ajudar?
