Subject: Transactional behaviour with trigger

Hi,
I create two records in a transaction in two different tables: customer
and contactaddress. customer has a foreign key to contactaddress.
I also have third table, customeraddress, which is a materialized view
of the join of customer and contactaddress
For the table customer I have a trigger(function) that inserts a record
in this third table (which works OK as the record is added):
....
INSERT INTO customeraddress(customer, customernumber, lastname, zipcode, city,housenumber, address)
VALUES(NEW.objectid,NEW.customernumber,NEW.lastname,NULL,NULL,NULL,NULL);
For the contactaddress I also have a trigger(function) that should
update the record in the third table with the additional info of the
contactaddress:
....
SELECT INTO customer_record objectid FROM prototype.customers WHERE contactaddress = NEW.objectid;
IF customer_record.objectid IS NOT NULL THEN
UPDATE customeraddress set zipcode = NEW.zipcode, city = NEW.city, housenumber = NEW.housenumber , address = NEW.objectid
WHERE customer = customer_record.objectid;
This last trigger is executed but customer_record.objectid seems to be
always NULL as if the the customer record is not visible. Is that
correct or is there something wrong with the SQl above?
In other words:
1. start transaction
2. add customer record
3. fire customer insert trigger -> copy record to materialized view table
4. add contactaddress record
5. fire contactaddress insert trigger -> update record in materialized view table -> no customer record???
6. end transction
TIA
