Custom UI control not working because property names get changed by minification.

[shvelo]

I'm trying to make a custom UI controller, but because minification changes all the object property names in Shaka libraries, I cannot access any of them. The example in https://shaka-player-demo.appspot.com/docs/api/tutorial-ui-customization.html does not work at all because this.parent is undefined, having changed to this.l, I can't even find what this.eventManager is changed to.

Is there anything I can do besides using the uncompiled player?

Hi @shvelo
Thanks for bringing this up, I will update the tutorial!

Try adding your custom button to build/types/ui and then running build/all.py.

You can also forgo extending shaka.UI.Element if you don't need it's members and just implement shaka.extern.IUIElement like the close button does on our demo page.

You should be able to extend shaka.UI.Element and take advantage of things like this.eventManager without adding your custom button to the library. We'll take this as a bug and try to fix it in the next release. In the mean time, adding it to the library as @ismena described should be a usable workaround.
Thanks for reporting!

Ok, this should be working in the latest master now even without the above workaround. Please, let us know how it goes!
