NEW ISSUE: Getting or deleting individual attachments

["Michael Rowley" <michael.rowley@activevos.com>]

 

TARGET: WS-HT

 

DESCRIPTION:

 

Currently there are operations for getAttachments(name) and deleteAttachment(name).  These get or delete _all_ of the attachments of the given name (names are not unique, so there may be several).  It should be possible to look at single attachment and possibly delete it, without having to always look at and delete all the attachments that share a name.

 

This is especially important when you have a UI that presents a list of attachments to the user.  The user should be able to click on one and see just that attachment, or delete one, and know that only that attachment will be deleted, even if others share the same name.

 

PROPOSED RESOLUTION:

 

Introduce the concept of attachment IDs.  Each attachment would have a unique ID within the process.  The attachment IDs would be returned as part of the getAttachmentInfo structure.

 

Introduce two new operations:

getAttachmentByID(attachmentID)

deleteAttachmentByID(attachmentID)

 

The addAttachment() function also needs to be changed to return an attachment ID.
