JSF E O PROBLEMA DE N CHAMADAS A UM MÉTODO GETTER

Imagine que o método abaixo possui um value-binding numa h:dataTable por exemplo.

public List<Cargo> getCargos() 
    return service.findAll(); // processo custoso
}

	-- obtem parametros da NLS (National Language Support) da sessão do usuário
	select * from NLS_SESSION_PARAMETERS

	-- altera NLS_LANGUAGE
	ALTER SESSION SET NLS_LANGUAGE='BRAZILIAN PORTUGUESE'

	# verifica encoding do arquivo
	$ file -I script_perebento.sql
	$ file -bI script_perebento.sql

	# converte arquivo de ISO-8859-1 para UTF-8
	$ iconv -f ISO-8859-1 -t UTF-8 script_perebento.sql > script_bonitao.sql

	-- run as a privileged user

	select dbms_xdb.gethttpport as port from dual;

	begin
	dbms_xdb.sethttpport('8081');
	end;

	-- Tendo problemas com "ORA-12519, TNS:no appropriate service handler found"?
	-- dica: http://en.newinstance.it/2007/06/01/ora-12519-tnsno-appropriate-service-handler-found/
	-- Basta rodar este comando e reiniciar o listener (OracleXETNSListener):

	ALTER SYSTEM SET PROCESSES=150 SCOPE=SPFILE;

	-- comando para listar usuarios conectados no oracle

	SELECT s.username, s.program, s.logon_time
	FROM v$session s, v$process p, sys.v_$sess_io si
	WHERE s.paddr = p.addr(+)
	AND si.sid(+) = s.sid
	AND s.username = 'MEU_USUARIO';
