md-select not working properly with Angular 1.7.7

Current behavior:

Angular 1.7.7 results in a problem for the Angular Material md-select directive when the directive has the required attribute, has a parent with an ng-if, and the md-select's ng-model is given an initial value. The directive incorrectly flags a required error and the displayed select option shows a trailing asterisk.

Expected / new behavior:

The md-select should not flag a required error and the displayed selected option should not show an asterisk.

Minimal reproduction of the problem with instructions:

In Controller:

$scope.selectModel = 'option1';
$scope.showSelect = true;

In View:

<md-input-container ng-if='showSelect'>
  <label> Select </label>
  <md-select ng-model='selectModel' required>
    <md-option value='option1'> Option 1 </md-option>
    <md-option value='option2'> Option 2 </md-option>
  </md-select>
</md-input-container>

AngularJS version: 1.7.7

AngularJS Material version: 1.1.12

Browser: Chrome 71.0.3578.98 | Firefox 64.0.2 | Edge 42.17134.1.0

It works for me:

Please provide a runnable demo, code and screenshots alone are not enough.
The example code is also incorrect: the label element is not closed.

The issue appears when you add an ng-if to the md-input-container.

[Mike-Bauer]

Correct, the issue does appear when you add an ng-if to the md-input-container or to a parent div as shown in this example.

Just in case it wasn't clear, this works fine with AngularJS 1.7.6 (demo).

This appears to have been caused by 005dd97.

works in older version 1.7.6 causing problem in version 1.7.7

I'm working on a fix but in the mean time using NG-required=“true“ instead of plain required should work.

[jmkrimm]

Oddly enough using required="true" also works.

[Narretz]

Yes, that is because we considered the value of the required attribute for the requirement status. However the presence of required already means that the control is required.
