Question

我已经阅读了SO提出的所有先前问题，但是我无法使其正常工作。这就是问题所在：

减速器1：

export interface ApplicationState extends EntityState<Application> {
  draftApplication: Application;
}

export const adapter: EntityAdapter<Application> = createEntityAdapter<Application>(
);

export const initialState: ApplicationState = adapter.getInitialState({
  draftApplication: null
});
// createReducer...

减速器2：

export interface InvitationState extends EntityState<Invitation> {
  loading: boolean;
}

export const adapter: EntityAdapter<Invitation> = createEntityAdapter<Invitation>(
);

export interface State extends fromRoot.State {
  invitations: InvitationState;
}

const initialState = adapter.getInitialState(
  {loading: false}
);
// createReducer...

我想将它们组合在功能模块中，如下所示：

import {ActionReducerMap} from '@ngrx/store/src/models';

import * as fromInvitation from '../invitation/store/invitation.reducer';
import * as fromApplication from '../application/store/application.reducer';
import * as fromRoot from '../../reducers';

export interface AnnouncementState {
  applications: fromApplication.ApplicationState;
  invitations: fromInvitation.InvitationState;
}

export const reducers: ActionReducerMap<AnnouncementState> = {
  applications: fromApplication.reducer,
  invitations: fromInvitation.reducer
};

export interface State extends fromRoot.State {
  announcement: AnnouncementState;
}

但是，当我随后在其中一个化简器上触发某些动作时，实体函数却不会，例如添加一个实体。addOne()例如只是坐在那里，什么也不做。没有错误，没有商店更新。只是应用程序不更新商店。知道为什么吗？

编辑：

尝试了几件事之后，问题似乎出在我从Firebase Firestore分派。我的应用程序中的服务执行以下操作：

    .subscribe(
        changes => changes.forEach(change => {
          console.log('Found invs: ', change.payload.doc.data());
          this.store.dispatch({
            type: `[ Invitation ] ${change.type}`, <-- Action to trigger
            invitation: {
              ...change.payload.doc.data(),
              id: change.payload.doc.id,
            }
          });
        })
      );

当我从组分中派出时，效果很好。不是通过服务。

功能模块中的多个NGRX实体-Reducer不会addOne（）
