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
executeSELECT tests.func1() in psql I can see both notices.
 

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