I'm currently working with the RallyJiraWIC and am running into some problems syncing the comments from Jira to discussions in Rally.
I am using YAML for my config file, and added the following:
RelatedObjectLinkers:
RallyAttachmentLinker:
RallyJiraCommentLinker:
The attachments are syncing as expected, but the comments are not.
I have tried adding comments to the FieldMapping section of the config file, but this led to a list object containing the comment being mapped to the value in the connector, ultimately leading to the value being skipped over when pushing to Rally.
