this.args is undefined inside component after enabling proxy

[gokatz]

In glimmer components, the named arguments are supposed to be accessible via this.args property. But after enabling proxy access, I can't access the arguments and it is coming something like Symbol(magic-prop). With the previous SHA, I can able to get the args without any issue.

Reproduction: https://codesandbox.io/s/my-app-tdwwx
In this sandbox, name argument has been accessed inside formattedName getter.

Is there any other way I can access the arguments? Thanks for any help.

yes facing the same issue in glimmer components when using commit b6a3ecd in ember-source
this.args.prop-name gives undefined in its component.js

Looks like something went wrong in #17835. @pzuraq

It’s more likely that the way that GlimmerComponent assigns args to the instance of the class is not compatible with the new autotracking strategy, since we test args out with a “Glimmerish” component that implements the same API. I’m currently working on fixing the transpilation bugs that keep popping up, but then this will be my next priority.

This should be fixed by glimmerjs/glimmer.js#201

We're facing this as well. Thank you for your swift work, @pzuraq
