How to get current value of State object with @ngrx/store?

Question

My service class, before calling a web service, needs to get a property called dataForUpdate from my state. Currently, I\'m doing it like this:

Extra comment. When I use this._store.value.StateReducer.currentPeriod.id

Transpiler return "app/state/stateService.ts(133,35): error TS2339: Property 'StateReducer' does not exist on type 'AppState'."

constructor ( public _store: Store) {

    const store$ =  this._store.select ('StateReducer');

    .../...


    let saveTransaction = this.actions$
                  .filter (action => action.type==SAVE_TRANSACTION )
                  .map (action => { return { type:SAVING_TRANSACTION, payload : action.payload };  } )
                  .mergeMap ( action => this._transactionService.updateTransaction (
                                                            this._store.value.StateReducer.currentProfile.id, 
                                                            this._store.value.StateReducer.currentPeriod.id, 
                                                            action.payload),
                                (state, webServiceResponse) =>  { return { type:TRANSACTION_UPDATED, payload :null  }; }) ;





}

To fix issue, I have changed BehaviorSubject.d.ts in rxjs\subject folder :

import { Subject } from '../Subject';
import { Subscriber } from '../Subscriber';
import { Subscription } from '../Subscription';
export declare class BehaviorSubject extends Subject {
    private _value;
    private _hasError;
    private _err;
    constructor(_value: T);
    getValue(): T;        
    value: T;             <=== I have changed it to value: any;
    _subscribe(subscriber: Subscriber): Subscription;
    _next(value: T): void;
    _error(err: any): void;
}

Not sure if it's a legit modification ;)
