带ngrx的CombineLatest不更新更改

Question

I have following code:

this._loadingStateSubscription = combineLatest(
      select(fromTreeSelector.selectLoadingState),
      select(fromFinanceSelector.selectLoadingState),
      (isTreeLoading, isFinanceLoading) => {
        return isTreeLoading && isFinanceLoading;
      }
    )
      .subscribe(isLoading => this.isLoading = !isLoading);

the problem is, I the subscription is not updating on changes. But below I have this code

this.store.pipe(select(fromTreeSelector.selectLoadingState))
      .subscribe((isLoading) => {
        // this.isLoading = isLoading;
        console.log("isLoading", isLoading)
      });
    this._loadingStateSubscription = this.store.pipe(select(fromFinanceSelector.selectLoadingState))
      .subscribe((isLoading) => {
        // this.isLoading = isLoading;
        console.log("isLoading", isLoading)
      });

and I get a console log message each time it updates.

both selectors looks like this:

export const selectLoadingState = (state: AppState) => state.structures.isLoading;

any idea on this?

Ok I figured out:

this.store.select(fromTreeSelector.selectLoadingState),
this.store.select(fromFinanceSelector.selectLoadingState)

I have to add this.store now it is working.
