View with LONGs give blank columns

I want to join two tables into a view.  Each table has a LONG column. 
When I SELECT from the view, the first LONG is blank.  If I change one of
the LONGs to a VARCHAR, it works fine.  How can I get around this problem?

 CREATE TABLE prima (
   oid INTEGER,
   CONSTRAINT prima_pk PRIMARY KEY(oid),
   val long DEFAULT '')
//
 CREATE TABLE sec1 (
   oid INTEGER DEFAULT SERIAL,
   CONSTRAINT sec1_pk PRIMARY KEY(oid),
   CONSTRAINT sec1_fk FOREIGN KEY(oid) REFERENCES prima(oid) ON DELETE
CASCADE,
   val long DEFAULT '')
//
 CREATE VIEW V2 (OID, val, VAL1) AS
   SELECT P.OID, p.val, S1.VAL
   FROM PRIMA P, SEC1 S1
   WHERE P.OID = S1.OID
   WITH CHECK OPTION
//
 INSERT INTO v2 (oid, val, val1) VALUES (1, 'prima a', 'sec1 a')
 //
 INSERT INTO v2 (oid, val, val1) VALUES (2, 'prima b', 'sec1 b')
 //
 INSERT INTO v2 (oid, val, val1) VALUES (3, 'prima c', 'sec1 c')
 //
 select * from v2
