Thanks Stewart!!

Again, I wont be able to differentiate the scenarios

1. When the date field is empty

2. When the date field is having an Appian default validation

as in both the cases, the local value remains false.

The requirement for the link is that it should be disabled only when any validation error occur.(user defined or Appian default)

The link should remain enabled when the field is empty.

I created a very basic test interface where you can set a local!variable as a Boolean, initialised to false, which controls whether the link is disabled or not; and in the Date field an a!save() that saves true to this variable if the value of the variable for the date field a value, and saves false if the value of the date variable is null. The effect is that the link is disabled and remains disabled until you enter a valid date.

Here's the test:

a!localVariables(
  local!isDateValid: false,
  {
    a!dateField(
      label: "My Date",
      value: ri!myDate,
      saveInto: {
        ri!myDate,
        a!save(
          local!isDateValid,
          fn!not(fn!isnull(ri!myDate))
      )
    }
  ),
    a!checkboxField(
      disabled: true,    
      label: "Is Date Valid?",
      choiceLabels: {"Yes","No"},
      choiceValues: {true, false},
      value: local!isDateValid
  )
  }
)

Thanks Mike !!

Yes, no data is passed into the rule input.

According to the requirement, the link should be disabled only when there is any validation error and not when the field is empty.

Since a flag cannot be given for this scenario, I am back to square one. Anyway i will try again .

If you'll look at the actual saved value coming from the date field, I believe you'll find in your screenshot example that when the user types text into the date field, for example - no actual data is passed into your local / rule input variable. So in general we have no way of telling whether invalid data has been entered into a date field, however you should be able to design around the fact that the value will still be null in such a case.
