$controller_name in Page.php makes blog category etc. fail

[lerni]

Adding private static $controller_name = PageController::class; to Page.php causes Blog Categories etc. to fail. One way to work around this would be, to add static $controller_name = BlogController::class; to Blog.php, but may there is a smarter way fixing this for other instances that extend Page.php?

Should this be "fixed" in Blog (👍) or not (👎) ?

If not in Blog.php, can you pleas outline where and how or why not.

Hmm, I wonder if the code that fetches this (SiteTree::getControllerName()) should look for an “uninherited” config value instead of any value that’ll inherit from parent classes? I’m not sure if that would be a BC-break though.
