[CDBI] Committing on delete

Hi,  I'm sorry about having to ask such a basic question.

I'm trying to add transactions to my database.  I have been able to 
commit insertions and edit records but I really can't work out how to 
commit deletions.

Trying update or dbi_commit  on the object I have just deleted gives me 
the error "Can't locate object method "x" via package 
"Class::DBI::Object::Has::Been::Deleted" which I can understand as I'm 
trying to call it on an object I have just deleted but I can't work out 
how I am meant to commit the change.

I've been looking in the docs but can't seem to see an example of 
transactions that involves a deletion.  I apologise if this has already 
been covered somewhere.

Thanks in advance for any help you can give me.

Nick
