SINCE VERSION 2.7.0
This condition was introduced in version 2.7.0 and replaced the A field is/isn't initialized (deprecated) condition which had a limited subset of features.
Purpose
Using this condition you can make sure that one or multiple fields either need to have a value or be empty in order to execute a transition. The following options are available:
- A field is required.
- A field must be empty.
For cascading select fields both levels are being considered and need to have / not have a value.
