Email This Issue offers custom field types to use screens (e.g. in workflow transition views) to specify parts of the emails being sent.
Issue Attachment Selector Field
SINCE VERSION 6.3.0.3
This custom field type allows you to select existing attachments in an issue. The field can specify attachments to be attached to emails sent via event notifications, the transitions or when sending bulk emails.
Selected attachments are rendered as links with inline editing supported.
Use Case - Specify Attachments During Workflow Transition
Add the attachment selector to the screen displayed by the transition you want to use for sending emails.
Users will be able to select the attachments to attach to the outgoing emails using this field. To do this, configure the post function to refer to the attachment selector field.
Use Case - Attach Selected Attachments in Event Notification
Configure Email This Issue Event Notifications to add attachments to the email from the selector field.
Use Case - Anything
You can freely use this custom field type for your own purposes when you need to select attachments. The use of the field type does not require you to send emails at all.
