Attachments in Workflow

Hi

I need to have an attachment in the workflow mailer, i am following the below approach

Create an attribute
Type : Document
Source : Send
Frame Target : New Window
Attach Contenxt (check box) : yes (Checked)

and attached the attribute to one of the exisiting message...

using
wf_engine.setitemattrdocument
(to refer the attributes and using PLSQLBLOB to call the attachment)
in the package.


Using the temp table for testing purpose... before wf_engine.setitemattrdocument and after

wf_engine.setitemattrdocument

the temp table is updated with the data during the before and after of wf_engine.setitemattrdocument... where as the mailer

attachment is not working..
