  Just noticed this error in console from the Angular bundle of the most recent release Wijmo 5.20192.624. I have verified this problem did not exist in the previous release 550.

  

  Steps to Repeat:

  1. Find the calendar reference
  2. Set its value to null
  3. call dispose() method

  Note: This only seems to be an issue of Angular2. I tried AngularJS which is good.

  Code Sample:

  
  
  import { Component, ViewChild, AfterViewInit } from '@angular/core';
  import { WjCalendar } from 'wijmo/wijmo.angular2.input';
  
  @Component({
      selector: 'prototype-calendar',
      template: `
      <div class="ui container">
  
          <wj-calendar #calendar>
          </wj-calendar>
  
      </div>
      `
  })
  export class PrototypeCalendar implements AfterViewInit {
  
      @ViewChild('calendar') calendar: WjCalendar;
  
      ngAfterViewInit() {
          console.log(this.calendar);
          this.calendar.value = null;
  
          setTimeout(() => {
              this.calendar.dispose();
          }, 5000);
      }
  }

  Thanks a lot. Please test whether other input control elements have this issue as well. From stack trace, it looks like this error is generic, not particularly related to Calendar.

  Hi James,

  I have checked the other Input controls, but this issue seems to arise only in the Calendar control. But, thank you for your suggestion.
