Global temp table trigger error on Oracle AS

Question

we have a set of triggers that load a temp table in the before delete,update and process the table in an after statement trigger. the data that's loaded is a complaintid and when the complaintid is selected into a variable in the after statement, a No data found error is fired. This only happens on Oracle AS both 9i and 10g, it does not happen on jboss. All the app servers use connection pooling and they are 9i Enterprise Edition Dedicated database servers.
Is it possible that there is a bug in Oracle AS that allows multiple sessions to affect the same global variables ?
Sorry it's a long one, but I wanted to include everything I could
table creation script.
CREATE GLOBAL TEMPORARY TABLE TEMPEVENTS
(     COMPLAINTID VARCHAR2(20) NOT NULL ENABLE,
     COMPLAINTEVENTID NUMBER NOT NULL ENABLE,
     STARTDATE DATE,
     EVENTTYPE NUMBER,
     EVENTSUBTYPE NUMBER,
     DELETED NUMBER
) ON COMMIT DELETE ROWS
Before update trigger-- as a test I saved the data in a permanent table and all columns have usable values.
create or replace trigger BeforeUpdateReportDataROW
BEFORE Delete or Update of deleted, startdate on complaintevents
FOR EACH ROW
BEGIN
IF (DELETING AND :old.deleted = 0) OR (UPDATING AND :new.deleted=1 AND :old.startDate = :new.startDate) THEN
     TEMPDATA.v_triggerType := 'D';
ELSIF UPDATING AND :old.deleted=1 AND :old.startDate = :new.startDate THEN /*undeleting*/
     TEMPDATA.v_triggerType := 'U';
ELSIF UPDATING AND :old.startDate != :new.startDate THEN /*new date*/

Answer 1

CREATE GLOBAL TEMPORARY TABLE test_glb ON COMMIT DELETE ROWS
AS SELECT * FROM test1;btw I'm assuming you are just using the SELECT statement to copy the definition of test1. Since DDL statements commit, there will be no rows in test_glb after creating it.
