Feature Module it's not working about ngrx-wieder HOT 5 CLOSED

You need to put any actions that can be undone/redone into allowedActionTypes. You can then also put some of them into mergeActionTypes in order to undo/redo them in whole when actions of a single type occur directly after each other. A good example for this are sliders, have a look at the example in the readme.

Either way, all actions for undo/redo need to be in allowedActionTypes. Leaving it empty will make all actions undoable/redoable. Hope this is clear, otherwise don't hesitate to ask again.

I would be nice if you could give this library a star when it's working for you :)

EDIT: Ah, I see your error now. I'll look into it.

EDIT2: When I corrected your StackBlitz to use only allowedActionTypes the error was next is undefined & state is undefined. And that was exactly the case for your setup: you didn't provide an initial state. Here's a fixed StackBlitz: https://stackblitz.com/edit/angular-fitmtz

Can you provide more information or a reproduction on https://stackblitz.com/ or similar?

How are you integrating the library and what exactly is not working properly? Which versions of Angular, NgRx and ngrx-wieder are you using?

Here is the stackblitz example https://stackblitz.com/edit/angular-xqf5h9. Doing in the stackblitz worked, because i copied exactly like in your example. Maybe i was not seeing the error, but I noticed that you must use "mergeActionTypes" to work and not "allowedActionTypes", maybe i undestand wrong the documentation because english it's not my first language.

Ok, that was exactly the problem, i wasn't passing the initial state to the reducer. And passing the initial state i was able to use the allowedActionTypes. Thanks for this library, worked perfectly in my project that uses OpenLayers, i was able to undo and redo the zoom and the center of the map

Great to here that it worked out! I'll soon update the library to be in line with the new ngrx functions like createReducer. Some things changed with the new NgRx version and I'll have to see how to deal with that.

Sounds like a cool use-case, your welcome to share a link once it's public. This way people can see some examples of the library in action.
