patchvalue or setvalue of formbuilder does not mark field as dirty or touched : <p>I have a multi step form where user traverses back and forth to the form. I save the form data in service and when he comes back i use patchvalue to patch all the data to form. I tried setvalue also, but the form fields are not marked as either dirty or touched. How to i mark fields updated as dirty and touched? </p>

<pre><code>this.formBuilder.pathValue(formData);
</code></pre>
