formio.ts

import { Component, AfterViewInit, ViewChild } from '@angular/core';
import { FormioComponent, Formio } from '@formio/angular';

@Component({
  template: `
    <formio src="https://examples.form.io/example"></formio>
    <button (click)="submitFormio()" class="btn btn-primary">Submit</button>
  `
})
export class FormRenderComponent implements AfterViewInit {
  public formio: Formio;
  @ViewChild(FormioComponent) formioComponent: FormioComponent;
  ngAfterViewInit() {
    this.formioComponent.formioReady.then((formio) => {
      this.formio = formio;
    });
  }
  submitFormio() {
    this.formio.submit().then(() => {
      this.route.navigate(['...']);
    }):
  }
}

it works now, maybe you know how to catch submersion of internal form via this construction?

@travist do we have formio.on(...) function here?
