this was on the package upgrade?

Sorry for the answer time I was very busy, I don't know but it's here even after atom reloading.

Seems like in resizeNuclideTreeView you have a scope problem, I don't write coffeescript, but "->" is function() {} right ? The setTimeout callback is a new scope and "this" is not anymore your package scope. You have to use bind(this) to send the package scope to the setTimeout callback, this.getWidth will exist then :)
