Checking for nulls, empty strings, empty data types and active nulls makes for
a lot of code in message transforms.
The presence of .isEmpty() looks like a godsend, but how is it intended to work?
The following code produces the results shown below. Is this the way it's
supposed to work?
Thanks
Ian
