These variables works only, if the namespace supports subpages (according to $wgNamespacesWithSubpages)

As default $wgNamespacesWithSubpages contains the template namespace as subpage namespace, but frwikiversity overrides it with

'+frwikiversity' => array( 0 => 1, 6 => 0, 8 => 0, 10 => 0, 112 => 1, 113 => 1 ),

which removed that flag for templates (the 10 => 0 is the problem).

I suppose subpages were disabled in template space for things like [[v:fr:Modèle:0/4]]. I can't find any relevant bugs.

As you can see by browsing through [[v:fr:Spécial:Index/Modèle:]], it's clear that subpages are actually being used for documentation etc, so all the more reason to re-enable subpages in template space.

If you would like this to happen, could you please start a community discussion and see if there are any disagreements?

I can't seem to find this discussion: que s'est-il passé?

I had moved it on he concerned site: https://fr.wikiversity.org/wiki/Wikiversit%C3%A9:La_salle_caf%C3%A9/47_2013#Bug_57487_-_.7B.7BBASEPAGENAME.7D.7D_.26_.7B.7BSUBPAGENAME.7D.7D_ne_fonctionnent_pas_normalement

Nobody has answered on fr.v, so let's uniform this behavior with the other wikis.

Change 142980 had a related patch set uploaded by TTO:
Allow subpages in template namespace of frwikiversity

It seems that I forgot about this bug. Sorry!

Change 142980 merged by jenkins-bot:
Allow subpages in template namespace of frwikiversity

Again, sorry it took so long. Hopefully your template programming is now a little easier!

Thank you, I confirm that it's much better now.
