Issue: a!isNullOrEmpty() not working with blank a!map()

Harshit Bumb (Appyzie)

While trying to check an empty map, a!isNullOrEmpty and a!isNotNullOrEmpty are not working, rather giving opposite result. 

The result of 

a!isNullOrEmpty(a!map())

should be true but the function is returning false. Not sure if this is a bug but something that might need the engineering team's attention.

    Hmm, it does seem odd - that being said, I'm pretty sure behind the scenes this function is just doing a length() check on the value. If I do length(a!map()) it returns 1, so that's probably why this is returning false.

    If you'd like, you could probably submit a support case and have the team investigate it. My hunch though is that it is behaving as expected given the result using the length function.
