Basically I understand how the new yaml routes should be working. But the current issue baffles me. What I'm trying to do is use a different controller instead of the current ModelAsController. So someting like
this works very well, placing the fragment After: framework#coreroutes, just like the docs suggest. But now other urls like admin and dev are unaccessible. Of course 'After' may be anywhere after, so there should probably be a 'Before' as well. I'm thinking before framework#coreroutes.
But whatever I try, it always results in an error saying that two fragments want to be after each other. There's hardly any combination I didn't try, including renaming my module from aaa to zzz. I did trace the order in which the rules are parsed based on the output from ConfigManifest, but I just don't seem to be able to exactly position the fragment.
What am I missing?
