bb-date-range-picker bb-date-range-picker-valid directive not picking up validation change from a watch

[Blackbaud-KevinHutson]

Expected behavior

for bb-date-range-picker, with a from and to date,
I expect when I go from an invalid state to a valid state, that this value will be reflected in my controller.

Actual behavior

bb-date-range-picker's bb-date-range-picker-valid directive does not fire when going from invalid to valid.

Steps to reproduce

• Enter a valid from date
• Enter some junk for the to date (like "whatever")
• Notice isValid is false.
• Change the to date to a valid date and tab out of the field.
• The controller recognizing the change (invoked from an angular watch) does not include the new value. It's still false.

Plunker

Here is a Plunker that demonstrates the issue. We have 2 different components in Luminate NextGen that demonstrates this issue. Notice the watch and the console statement. It will not reflect the correct state of isValid, presumably because the watch fires before that change happens.

Some additional clarification since it may not be obvious from the description.

Load the page.
IMPORTANT: open the developer console.
There’s a log statement from index.js that fires when the watch happens.
Put in a valid from date.
Put in a bogus to date (say ‘foo’)
Notice isValid = false from the console.log.
Now fix the toDate to a valid date. The second you fix it, isValid will be true in UI but FALSE in the watch scope.

I don't know if there's any change we could implement to not make this happen. We might be able to to set isValid in our other watchers, but I'm not sure the vm.dateRangeForm.$valid has been updated yet.

Alternatively, depending on what you're trying to do, I can think of a couple workarounds. 1) . Use a $timeout which will let that next digest cycle pass. 2) . Watch the isValid property instead of watching myDate. Here's a plunkr using both of those techniques. http://plnkr.co/edit/UM4Dwpo5gr37vumPqM9V?p=preview
