I have a view that launches a confirmation dialog but instead of waiting for the dialog to return with a result, the code jumps straight to the 'then' portion of the promise. See code below:

ConfirmDialog.ts

import { inject } from 'aurelia-framework';
import { DialogController } from 'aurelia-dialog';

@inject(DialogController)
export class ConfirmDialog {
  private message: string;
  private controller: DialogController;

  constructor(controller: DialogController) {
    this.controller = controller;
  }

  public activate(message: string) {
    this.message = message;
  }
}

ConfirmDialog.html

<template>
  <div tabindex="-1" role="dialog">
    <div class="modal-dialog">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" click.trigger="controller.cancel()" class="close" aria-label="Close"><span aria-hidden="true">&times;</span></button>
          <h4 class="modal-title">Confirmation</h4>
        </div>
        <div class="modal-body">
          ${message}?
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" click.trigger="controller.cancel()">No!</button>
          <button type="button" class="btn btn-danger" click.trigger="controller.ok()">Yes</button>
        </div>
      </div><!-- /.modal-content  -->
    </div><!-- /.modal-dialog -->
  </div><!-- /.modal -->
</template>

SomeView.ts

import * as moment from 'moment';
import { inject, singleton } from 'aurelia-framework';
import { DialogService } from 'aurelia-dialog';
import { ConfirmDialog } from '../components/modal/confirmDialog';
import { InfoDialog } from '../components/modal/infoDialog';
import { StateStore } from '../common/StateStore';
import { Routing } from '../common/routing';

@singleton()
@inject(Routing, StateStore, DialogService)
export class SomeView {
    private routing: Routing;
    private commonState: StateStore;
    private dialogService: DialogService;

    constructor(routing: Routing, stateStore: StateStore, dialogService: DialogService) {
        this.routing = routing;
        this.commonState = stateStore;
        this.dialogService = dialogService;
    }

    public someButtonClickHandler(someArg: SomeType) {
      if (!this.routing.auth.authenticated) {
        this.routing.router.navigate('#/login');
      }
      this.dialogService.open({
        viewModel: ConfirmDialog,
        model:
          'Do you wish to continue'
      }).then((response) => {
        if (response.wasCancelled) {
          return;
        }

        this.dialogService.open({
          viewModel: InfoDialog,
          model: 'Why is this happening..'
        });
      });
    }
}

I have omitted the html for the view since it works and all bindings are firing correctly. This used to work, I updated the aurelia-bundler which caused a runtime error so I reverted back to a previous version of the bundler. The runtime error stopped but now it seems that Promise is being short circuited. I even tried checking out the project from version control and this keeps happening. Tried clearing the browser cache in case something was wrong there but no matter what I do, the "why is this happening..." always shows before any interaction can happen with the confirmation dialog. When I click 'ok' on the InfoDialog, the confirmation dialog is there underneath and clicking cancel or OK subsequently does nothing.

Any help would be appreciated.

这很可能是因为 beta 和 RC 之间的 aurelia-dialog 发生了重大变化。

尝试更改this.dialogService.open({...}).then(...)为this.dialogService.open({...}).whenClosed().then(...).

请参阅 RC-1 的发行说明：https ://github.com/aurelia/dialog/releases/tag/1.0.0-rc.1 。
