Problems with "NOTICE"-messages

I have two functions:

CREATE OR REPLACE FUNCTION tests.func1()
RETURNS integer AS
$BODY$
DECLARE
BEGIN
RAISE NOTICE 'notice';
PERFORM tests.func2();
RETURN 1;
END;$BODY$
LANGUAGE 'plpgsql' VOLATILE;

CREATE OR REPLACE FUNCTION tests.func2()
RETURNS integer AS
$BODY$
DECLARE
BEGIN
RAISE NOTICE 'SUBnotice';
RETURN 1;
END;$BODY$
LANGUAGE 'plpgsql' VOLATILE;

If I call SELECT tests.func1(), then in messages-dialog I can see a notice from tests.func1() only, but not from tests.func2() (as I know, PgAdmin has to show this notice with "CONTEXT....."). What's the problem? By the way, if I execute SELECT tests.func1() in psql I can see both notices.

I have this problem both in 1.6.3 and 1.8 versions of PgAdmin
