Multiple POST-MAPPING Processes Code Generation BUG

Question

We are testing OWB 10gR2, and we were very happy to see that there is option to include more than one postmapping operator.
The idea is to create mapping with two post-mapping operators and that:
- one procedure is executed in case of 'Post-Mapping Process Run Condition' = ON ERROR
- and other procedure in case of 'Post-Mapping Process Run Condition' = ON SUCCESS.
But, after implementation of this case, we were dissapointed. We discover that neither procedure is executed.. ?!?!
After analyzing generated code in 'finalize' method there is code like this:
IF NOT get_abort THEN
IF get_abort THEN
     BEGIN
As you can see this condition will never bee true ?!?
Doe's anyone have same problem?

Answer 1

1) If you have somehow got multiple post-mappings working, I would consider that to be buggy behaviour that you cannot depend on for future releases or upgrades. As such, building a solution that depends on this has risk.
2) You could always build a user-defined custom transformation that takes a list of tables to truncate and does so. Something like (untested, uncompiled, seat-of-the-pants written right here example to get you started):
create or replace procedure trunc_tables(tablist varchar2)
is
local_tablist varchar2(2000) := tablist;
this_Table varchar2(30);
nextindex number := 1;
begin
nextindex := instr(local_tablist,',');
while nextindex != 0 loop
this_table := substr(local_tablist,1,nextindex-1);
execute immediate 'truncate table '||this_Table;
local_tablist := substr(local_tablist,nextindex+1);
nextindex := instr(local_tablist,',');
end loop;
-- if no trailing semicolon there is still one table left
if length(local_tablist) > 0 then
execute immediate 'truncate table '||local_tablist;
end if;
end;
You could then reference this in your post-mapping procedure with a call to trunc_Tables('table1,table2,table3'), and could re-use this code across all mapping that need it.
Of course, if you have a lot of mapping-specific stuff to do then you might need to build custom transformations for each mapping that need to do different things as part of their post-process.
