Configure exclude for tablespace does not work.

Question

I have to exclude a tablespace from my full database backups. I have Level-1 and Level-0 backup script.
run the following command as per documentation.
CONFIGURE EXCLUDE FOR TABLESPACE DATA_TEMP;
To reconfirm, if exclude is set.
run SHOW ALL;
it shows that exclude is set properly.
Now i have to restore on another machine and before running the restore i run
RESTORE DATABASE PREVIEW, just to confirm if backup health is ok.
it gives me error
RMAN-00571: =========================================================
RMAN-00569: === ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ================================================
RMAN-03002: failure of restore command at 09/28/2007 05:57:32
RMAN-06026: some targets not found - aborting restore
RMAN-06023: no backup or copy of datafile 10 found to restore
The datafile 10 mentioned in the above error is the 'DATA_TEMP' tablespace which was excluded before taking the backup.
Restoring the database with RESTORE DATABASE command goes fine and restores the tablespace "DATA_TEMP".
My question is why RMAN have backuped up a tablespace which is in the exclusion list. i think rman reads its environment settings before starting a backup.
Have any one have experienced this before. the documentation says nothing about this.
Thanks.
