Thank you for noticing this issue.

You’re correct; the post parameter should be `this.args.post` instead of `this.post`.

> There are getters in `PostSmallAction` for `code`, `createdAt` and `path`, but (again) `this.post` does not exist and `username()` seems to have a bug as well (there is no `action_code_who` in `this.args.post` ?) , so those attributes stay empty.

`username` is a bit misleading here. `action_code_who` is indeed correct but is used by some plugins like the `assign` plugin, so it’s not always present in the `post` object. To get the user who created the small action, you can use `@post.username`

I wasn’t sure if I could push changes to your PR, so I opened the one below to address these issues:

- fix the post argument passed both to the transformer and the custom component
- rename the `username` argument to `who` minimizing the confusion around this argument
- add tests to verify the arguments are passed correctly
