Issue description

Current behavior: When i load the data via an http service, the messages don't show until i hover the input box.

Expected behavior: Messages are always shown.

Steps to reproduce: Create a service with a remote call, assign the results to the variable that contains the messages. Messages are not seen until I hover over the input box.

messages: IMessage[] = [];
...

ngOnInit() {
    this.route.paramMap.subscribe((params: ParamMap) => {
      this.selectedId = +params.get('id');

      this.apiService
        .execute('GET', '/message/' + this.selectedId)
        .then((messages: IMessage[]) => {
          this.messages = messages;
        });
    });
  }

<nb-chat title="Thread" size="giant">
   <nb-chat-message *ngFor="let msg of messages" [type]="text" [message]="msg.text"
                        [sender]="msg.sender" [reply]="msg.sender!='brixiamoto'">
   </nb-chat-message>

   <nb-chat-form (send)="sendMessage($event)" #chatInput>
   </nb-chat-form>
</nb-chat>

Hi! Can I ask how did you fix this?

[lyradgnuhz]

If anyone is still looking for answers. Just add the detectChanges().

import { ChangeDetectorRef } from '@angular/core';
this.changeDetectorRef.detectChanges();
