This gets interesting now :)

Test #1:
Go ahead and load page and click the date TRIGGER icon and you get the calendar properly.
[test passes]

Test #2:
Go ahead and FIRST press the "test" button. We get a popup. This is "expected" due to change in ext 4.8.3 that fires select on setValue. click ok
Now go ahead and click the date TRIGGER icon
Expectation: Get the calendar widget
Actual: We get the 'oh crap' popup.

Well that is unexpected :)
We certainly should NOT see the select event firing when I trigger the calendar widget from the DateField.
