BUG: md-input does not lift when setting form value

[chriseenberg]

Bug

What is the expected behavior?

I expect the placeholder to lift above the text when there is an input, even when done programmatically.

What is the current behavior?

The placeholder stays down when setting value of an input field programmatically through from.controls.

What are the steps to reproduce?

Create a form with the form builder, then set a value like this:
Code to reproduce:
this.form = this.fb.group({ 'email': [null] })

<md-input-container class="form-full-width"> <input md-input placeholder="Email address" [formControl]="form.controls['email']"> </md-input-container>

this.form.controls['email'].setValue("testingapp@testingapp.com");

What is the use-case or motivation for changing an existing behavior?

I want to be able to set a value of an input field and have it displayed right when i load some data.

Which versions of Angular, Material, OS, browsers are affected?

Angular cli 1.0.0-beta.25.5, material: ^2.0.0-beta.1, Angular version: ^2.3.1

Is there anything else we should know?

I may be doing stuff wrong, as i would expect this bug to be caught sooner? please excuse me if this bug has already been reported.

Kind regards Chris

If you're using 2.0.0-beta.1, you are probably seeing the setValue issue that has since been fixed in master. Testing in plunker with the master build, it seems to be working now: http://plnkr.co/edit/Z3AR9NqqD5cq8ymUF2ye?p=preview. As soon as we release, you should be able to upgrade to get the fix.

The exception is using setValue with an onPush change detection strategy, for which there is already an issue.
