Bug ID: 59197
Summary: Flow: page fails to load "InvalidDataException(
'Missing Posts:...)"
Product: MediaWiki extensions
Version: master
Hardware: All
URL: http://ee-flow.wmflabs.org/wiki/Talk:Sandbox
OS: All
Status: NEW
Severity: major
Priority: Unprioritized
Component: Flow
Assignee: wikibugs-l@lists.wikimedia.org
Reporter: sp...@wikimedia.org

Classification: Unclassified
Mobile Platform: ---
On ee-flow, Talk:Sandbox shows just
Error
Failed to load the requested data.
The exception (below) is
Missing Posts: {"2":"050d40cb239ff00fc8b1fa163e68c4ac"}
I had earlier failures trying to add reply posts to this page, possibly because
ee-flow didn't have the workflow_user_ip SQL patch. Maybe those failures left
ee-flow in an inconsistent state.
I am able to view an individual topic from Talk:Sandbox that I had permalinked
http://ee-flow.wmflabs.org/w/index.php?title=Talk:Sandbox&workflow=050b9f659413f00fc8b1fa163e68c4ac
(though there's some kind of username display glitch there).
This suggests that Flow code needs to be more robust when loading a board. A
missing post should appear as, e.g. a pink errorbox
[Missing post 050d40cb239ff00fc8b1fa163e68c4ac]
FWIW the code has a comment
// TODO: fake up a pseudo-post to hold the children? At this point in
// dev its probably a bug we want to see.
debug.log contains
