setState can only update a mounted or mounting component warning
See original GitHub issueHi,
I’m trying to use this boilerplate with react (react branch) but when I try to set a state (this.setState) I keep getting this warning in the console:
warning.js?8a56:33 Warning: setState(...): Can only update a mounted or mounting component. This usually means you called setState() on an unmounted component. This is a no-op. Please check the code for the ReactComponent component.
The component isn’t unmounted, even with the easiest state change I get the same warning. Maybe this has something to do with the fact that it’s a chrome extension?
I hope someone can help me out here. Thanks in advance,
Giel.

I was investigating this and I found something curious. The problem that you related in fact exists and it is related to the React Hot Reload, I don’t know exactly what is happening, but if you include the es2015 babel preset, everything works fine. Later on, I’ll update the React Hot Reload to see if it’s fixed.
I also ran into this problem. If you need a quick fix, remove the binding in the constructor and bind it when you call it in the JSX part.
Do this:
<form className='uk-grid-small' data-uk-grid onSubmit={this.updateResults.bind(this)}>Don’t do this:
this.updateResults = this.updateResults.bind(this)
