onNext() get called during RxLoader creation

[huahou]

I have a fragment hosted by an activity. Within the fragment, I create an RxLoader by:

RxLoader1<DealSavable, MyData> myLoader;

myLoader = RxLoaderManager.get(getActivity()).create(..., new RxLoaderObserver() {
@OverRide
public void onNext(MyData value) {
}
...
});

myLoader.restart();

The problem is: If the loader retrieved some data, and after that, if the activity is re-created, during the above "create()" method call, the onNext() is called immediately with previously loaded stale data.

Is this a bug? How can I make sure that onNext() is called only when "restart()" is called?

This is by design. Normally you'd want to use the previous result to recreate your ui state after an orientation change.

Thanks for the feedback. Is there a way to override this default behavior?

[evant]

Not really, if you have some transient state, you could store a flag that determines if you've handled it I guess. I haven't really thought about a good api for that.

I've actually run into this issue myself, (I was showing an error toast and I didn't want it to show again after you rotated), maybe a loader.clear() method would be good solution.

[huahou]

Neither RxLoader nor RxLoaderManager have "clear()" method. Which "clear()" method are you referring to?

[evant]

Sorry, maybe I wasn't clear enough. I'm thinking out-loud about a future api to solve this issue. I thought maybe there could be a clear() method on RxLoader that would clear the cached value if you no longer want to get it on configuration changes.

[huahou]

that will definitely help.

Thank you for the quick fix! really appreciate!

I want to keep this open until I actually release a new version to maven central.
