Checking for empty multi-line container element?

[Sky Kimball]

Hi everyone,
 
A quick question about testing a multi-line workflow
container element: I've tried to use the expression
editor to check for whether there are any items in a
multi-line container element, but so far without
success.
 
I finally decided to go with a virtual attribute that
does the check programmatically. Does anyone know of a
way to do this in the expression editor?
 
Thanks in advance for your help.
