@xanderblinov have you a guess what happened there? I didn't use kotlin 🙈

[senneco]

@valeragit could you attach archived project? I dont have time to make kotlin sample project, but your sample can help to fix this issue.

[xanderblinov]

Hi guys! @valeragit could you try to replace kotlin class with java to determine error in kotlin implementattion or not?

[andrikeev]

I created sample project https://github.com/valeragit/KotlinMoxySample

could you try to replace kotlin class with java
I'll try later

[andrikeev]

I tried switch MainPresenter and MainActivity to plain java, it didn't work. Still can't generate proper LceView$$State class

[senneco]

Could you get stacktrace/error message?

Generated LceView$$State is similar to one from start post

[andrikeev]

It seems that there is a problem of generating ViewState for parameterized View. And problem is not related to Kotlin.
Simple workaround is to add one more interface that implements parameterized View with necessary type.

[senneco]

Oh, yes. Currently Moxy doesn't generate code for typed View. It's old issue, but still is in short list. There several problems to determine View type in annotation processor. We working on it.

You can contribute these feature to Moxy – annotation processor is much fun 😄

[andrikeev]

I try to figure out how to do it =)
