Create Trigger (PK from Sequence) in SQL Developer 1.5.1

Question

Hi all
I'm new to Oracle and am trying to create the equivalent of an autonumber field on a table using the Create Trigger (PK from Sequence) option (by right clicking on a table in SQL Developer).
I've set up a sequence called REQUESTID and when using the above option it generates the following SQL:
begin
execute immediate 'create or replace trigger AutoNumber '||
     ' before insert on "REQUEST" '||
     ' for each row '||
     'begin '||
     ' if inserting then '||
     ' if :NEW."REQUESTID" is null then '||
     ' select REQUESTID.nextval into :NEW."REQUESTID" from dual; '||
     ' end if; '||
     ' end if; '||
     'end;';
     end;
When I click Apply I get an ORA-00942 (table or view does not exist). Am I doing something daft here?

Never mind - sorted it - I created the table under a different Schema to the System login being used in SQL Developer and so didn't have the permissions to create the trigger on the table.
