Action "formedit" is provided by the Semantic Forms extension. Thus changing component to "Semantic Forms". If the issue is indeed SWM related this may very well be changed back again.

This was a bug in Semantic Forms, that has since been fixed - if Wikimedia Labs upgrades to the latest version of SF, the problem should go away. Thus, I'm reassigning this to "Wikimedia Labs". :)

@scfc - I just looked at the form being used, here:

https://wikitech.wikimedia.org/w/index.php?title=Form:Shell_Access_Request/Edit&action=edit

The issue is that the form doesn't have a "Watch this page" checkbox. You don't automatically have a page added to your watchlist just by editing it with a form - you do need to click that checkbox, if it's there, which it isn't here. Someone just needs to add it to the form definition.

(By the way, it's strange that there are two different forms defined for shell access requests, one "regular" and one "edit" (?) - but that's another story.)

Anybody having an idea which codebase this task is actually about?
SemanticForms got removed and it's not wikitech.wikimedia.org either.
(Also wondering where the "Shell Access Request" process is actually documented.)

@Aklapper - Semantic Forms was not removed, you can see it here:

https://wikitech.wikimedia.org/wiki/Special:Version

I also don't think the name change for this bug is correct - SF is at its latest version, 3.4. Unless that was just done.

Yeah, SemanticForms is deployed from master like normal extensions...

Oh right, I made that change. Umm...
