Hi! Long time since I looked over our plugins. After upgrading to 2.4.0 beta I encounter errors with uploading. The composer-editor.js class fails with “this.afterRefresh() is not a function”. To me it looks like this might be an old action in the ember Component class but I might be wrong. Finding nothing about it. Could this be some legacy or am I using deprecated code? Thanx ---

Do you have this issue in safe-mode ? ---

It’s with my own plugins installed so running in [safe mode](https://meta.discourse.org/t/53504?silent=true) doesn’t help me find the issue. This particular plugin uses the composer-editor component in a template file. I checked out v2.3.6 and searched for afterRefresh. It seems the composer-editor.js is using it differently. this.afterRefresh($preview); instead of this.sendAction(‘afterRefresh’, $preview); This at least seems to be the problem. ---

It was unclear from your post if you were thinking it was coming from plugins or core. Can’t help much without having access to code. But what you said is right `sendAction` is deprecated and shouldn’t be used anymore, actions are now simple closures. ---

Allright, so just calling the action as a function is the correct way now? Then I guess I’ll have to look over my code. I thought maybe it was a bug. ---

Yes calling it as a function should be the expected usage. ---

I hadn’t defined afterRefresh in the composer-editor tag parameters in the template file. I guess that is required.
