We would like to create a process that auto-starts every time an instance is created or updated and a string attribute is NULL. Is it possible?
Release : 16.0.0
Component : CLARITY BUSINESS PROCESS MANAGEMENT
It is not possible adding NULL from the helper UI in the Start Condition Builder. The UI will take the value of "NULL" as if the string had a value of, literally, NULL (as text).
However, it can be done entering the condition as text. In order to compare with the NULL value, it can be done with a condition like this:
task.prexternalid == null
(without quotes)
