Input form

[signal hazel]

I didn't understand what you're trying to do, but this.form.value will be a boolean value, then you cannot use it as argument of clickTwo(form: AllotmentTaskDTO)

Try this

return 
  !this.form.controls['title'].value && 
  !this.form.controls['partialAgreement'].value

And obviously, you want the button to be disabled when the function return true so

[disabled]="draftButtonDisabled()"

But I suggest to you to choose a reactive approach, leveraging status and value changes observables.

Nothing to do with my suggestions.
Now I have to go, but FYI, the right solution is to add a required validator to those two controls, and bind the disabled property of the button to the combination of their valid property.

If they are the only controls of their parent form

you can directly bind button's property to single valid property of the form.

If that works your setup has to be really weird.
I'd suggest you to look at my last message for the canonical solution to your needs.
