Description

Part 1

Visit https://www.mediawiki.org/wiki/Talk:Sandbox?workflow=abcd , the h1 and page title are

Internal error - {{SITENAME}}

Appending &uselang=qqx suggests the message is

(pagetitle: (internalerror))
(flow-error-invalid-action)

So the pagetitle message is looked up, but isn't getting parsed.

Part 2

Visit https://www.mediawiki.org/wiki/Talk:Sandbox?action=FOO , the h1 and page title are the same Internal error - {{SITENAME}}
Flow's InvalidActionException->getErrorPageTitle() is returning the better title 'nosuchaction' for this error, but it isn't appearing.

Version: master
Severity: normal

That is bug 58447.

Beyond that bug, Flow is creating its own OutputPage object that has no message handling hooked up at all.

Change 116631 abandoned by Spage:
Fix error page titles

Reason:
Yup, it's not this simple. I still think we can get ErrorPageError to do the work for us, just pass the full 'flow-error-CODE' at all times. It's crazy that ErrorPageError can't log the full $message text while displaying something friendlier to the user.
