What is the expected behavior?

When a FormControl call setValue method, the show the value.

What is the current behavior?

When a FormControl call setValue method, the don't show the selected value, only put the value into FormControl (I see in console.log(formcontrol.value)).

What are the steps to reproduce?

In component.html:
<md-select class="col-md-3" placeholder="Tipo*" formControlName="clientType"> <md-option *ngFor="let type of clientTypes" [value]="type"> {{ type.description }} </md-option> </md-select>

In component.ts:

this.clientForm.controls.clientType.setValue({id: '1', description: 'Test'})

The field stay with the same value of placeholder, "Tipo*".

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

Angular: 4.3
Material: 2.0.0-beta.8
OS: Windows 10
Browser: Chrome 60

Is there anything else we should know?

My english is very bad, sorry.

If you have objects as options' value, you must use the compareWith. Otherwise, the by-ref default comparison will never let it work right. Take a look at @rafaelss95's comment here: #6970 (comment).
