How can I make the TracRevisionLog display the same information as the version control system after an edit to a repository revision property?
The solution is the same as discussed here. The TracRevisionLog must be resynced with the repository after an edit to a revision property in the version control back-end. The trac-admin resync command can be used to resync the entire repository or a single revision. See trac-admin help or TracAdmin#FullCommandReference for more details. One can even create a hook to automatically resync the revision history in Trac with that in the repository following a property edit.
