If you edit an existing message in the Collaboration system, and then preview it, the preview correctly displays your changes, but your changes are lost in the Message body.

How to Reproduce:
1. Add a Collaboration Asset (keep all defaults)
2. Commit it
3. click add
4. enter subject and message text; click save
5. display message; click edit
6. change the text or add additional text;
7. click preview

The adds or changes appear in the preview section, but all the changes are lost in the message section.

Workaround:

Don't preview your changes.

thanks,

Ken
