create trigger fails with null pointer exception
------------------------------------------------

         Key: DERBY-630
         URL: http://issues.apache.org/jira/browse/DERBY-630
     Project: Derby
        Type: Bug
  Components: SQL  
    Versions: 10.1.1.0    
 Environment: windows 2000, sun jdk 1.5.0
    Reporter: mardacay


When i create a brand new database, and execute the following statements all in one transaction
or each of them in their own transaction, then it fails at trigger creation with null pointer
exception. if i exclude the schema names from statement, then it runs fine. (If S1 is ommited
from every statement then it runs fine). Once the version without the schema names run fine,
i can run the version that has schema names, fine also. 

create schema S1;

create table
  S1.PRODUCT(
    PRODUCT_ID VARCHAR(255) unique not null,
    VERSION BIGINT
  );
  
create table
  S1.CATEGORY(
    CAT_ID VARCHAR(255),
    NAME varchar(255) not null,
    VERSION BIGINT
  );

create table
  S1.PROD_IN_CAT(
    CAT_ID VARCHAR(255) not null,
    PRODUCT_ID VARCHAR(255) not null,
    VERSION BIGINT
  );
  
create trigger S1.product_v 
after update of version on S1.product
referencing new as n
for each row
mode db2sql
	update S1.prod_in_cat set version = n.version where S1.prod_in_cat.product_id=n.product_id;
