I ran into a ZPL issue today that caught me off guard,
-Looking to see if anyone can help me wrap my head around this one.
It seems that if a variable is populated with ‘Null’ the device function_Zebra Printer, Custom Template fails
This instance caught me off guard as we have used this button and device function for several months.
-In the past, if a variable = ‘Null’ the printed material would return a blank field.
One detail to note is that I was able to identify a difference in the Expression structure of my trigger function:
In the past, I structured the variables within the expression: [ AAAA|BBBB ]
-Whereas, when I was surprised to see the structure had been changed to: [ AAAA + ’ | ’ + BBBB ]
(I thought somebody rewrote expression at first )
I am not sure if this change is in consequence to a recent update?
-Any insight is helpful.
(I am weighing if I need to create a substantial long-term solution to mitigate this roadblock.)
