Render not called when dispatch

Hello

I am trying to port my project to Redux. My components are react already. And I added everything needed (or at least I think so) to obey the redux framework.

But my React Component wont re-render even if I use export default connect(state => state)(WorkspaceView)

The reducer gets called, the state is altred, but nothing happens. When I force a render manually it works.

I uploaded my project here https://dl.dropboxusercontent.com/u/11300320/PTG.zip , and the component I am writing about is called Workspace view. Just dload it, run npm install gulp and ./run. It uses electron.io therefore the run command Please help me !

Regards Carsten

Hi @K4stor I have looked into your code, it seems you are mutating your state in your reducer, you are pushing a new entry into operations array instead of creating a new array. See http://rackt.github.io/redux/docs/basics/Reducers.html or http://rackt.github.io/redux/docs/Troubleshooting.html in the first section. Your state needs to be immutable so that re-render is triggered. Hope it helps !

Yeah, mutating state is the reason for components not updating like 98% of the time. I’ve written up an answer on this in my FAQ. It’s not merged in yet, so I’ll link to the WIP branch: https://github.com/markerikson/redux/blob/merge-faq-page/docs/FAQ.md#why-isnt-my-component-re-rendering-or-my-mapstatetoprops-running
