Hi Guys. I started a new project, and I think I start it with the new 3.0.0-rc4. I want to use https://github.com/area17/twill-capsule-homepages package too. But after I fixed the capsule route ('admin.homepages.landing', to 'twill.homepages.landing',) I have an other error: "Undefined variable $formBuilder" I tried to find some idea in upgrade guide but nothing found. Do you have any suggestion, how can I fix this, and how can I use this capsule with 3.0? Thank you!
