RC6 Forms: when value is null, control is not disabled

Current behavior

form = new FormGroup({
   'first': new FormControl({value: null, disabled: true}, Validators.required),
   'last': new FormControl('Drew', Validators.required)
})

the control first will not be disabled

Expected/desired behavior first shall be disabled because disabled is true, even so the input is null. If the value is empty (‘’), it will not be disabled either. In other words, the input seems disabled only, and only if the input has a value defined

Reproduction of the problem

What is the expected behavior?

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 2.0.0-rc.6
• Browser: [ Chrome 52 ]
• Language: [ TypeScript ]

@Krisa We were running the disabled check too late. Should be fixed by #11257.

Oh hey. That’s pretty weird. So if you put value as null and the control is disabled and you have the required validator, something is going wrong. I’ll look into it!
