Disable state for ReactiveForms not working correctly

[kevinclerc]

Mini app sample which shows the problem:
https://stackblitz.com/edit/angular-mbvopj

Expected Behavior

When I toggle the disable state, I expect, that all fields are disabled

Actual Behavior

Only the text field gets disabled but the mat-select stays enabled.
Ps: The same happens with mat-slide-toggle as well.

Environment

• Angular: 8.0.0
• CDK/Material: 8.2.3
• Browser(s): Chrome
• Operating System (e.g. Windows, macOS, Ubuntu): MacOS / Windows

The problem is that you're swapping out the entire form group, rather than just disabling the existing one which our components aren't set up to handle. There's a fix for mat-select at #17872, but we probably need to make a pass over the other components.

Thx @crisbeto for your reply
The use case requires that I swap out the whole form. (It's some kind of generic form component). So I need to change the whole form.

Do you know, when this fix will be merged? Or can I add a workaround in my code to fix this?

I have the same problem and occurs with the mat-radio-group too 😢
