@miha-x64 how does your

RootPresenterTag.get()

look like?

It returns

Presenter<ARG, RET, HOST, PARENT, VIEW>

using its own type parameters. (generic class, non-generic function)

@miha-x64 does your

Presenter<...>

have the same generic contraints as the method?

Yes.

can you post some code of your

Presenter

? I've tired to implement it with a simple class and it works fine here

Sample code is here: https://github.com/Miha-x64/Flawless I'm using PresenterTag as a token, which is used by Fragment to get a Presenter.

Hm, seems fine to me. Maybe try to create a simple project reproducing this issue

The code is not fine. There's no way for compiler to know whether are type parameters really mapped to actual type arguments. 🙂
