We're currently setting up and testing Service Desk and have noticed some unexpected behaviour with regards to file attachments.
If an issue is created using the customer portal, and a file is attached, this file is visible on both the portal as well as within Jira.
However, if a file is attached to the issue in Jira, this file is not available on the issue in the portal.
Are there any permissions that control how attachments are viewed for the portal? I had assumed that, as the portal user could add attachments, they would also be able to view them if added in Jira.
