Description

Steps to reproduce:
1. Create DateField component
2. Set "editable" property of DateField component to "true"
3. Add a DateValidator for the "text" property of the DateField component, triggering on the valueCommit of the DateField.

Actual Results:
The "invalid" event of the DateValidator is fired 3 times whenever the DateField loses focus when an invalid date has been entered.

Expected Results:
The "invalid" event only fires once when losing focus on the DateField.

Workaround (if any):
N/A

Research:
This seems to be caused by the fact that the DateField component is actually a descendant of ComboBase, and implements a TextInput. When focus is lost, the focusOut event occurs at each level (DateField, ComboBase, and TextInput), which in turn ends up firing a valueCommit event for each of those levels. Therefore a DateValidator is triggered 3 times for an invalid date.
