Role Responsibilies with boolean

[Robert.vande.Berg@nuon.com]

All,
 
System: IS-U
Version: 4.6.4
AOSP 17
 
I have created a Standard Role type Responsibilities which looks at the
value of a boolean container element.
What I want:
If the boolean is FALSE (no X), then to users 1, 2, 3.
If the boolean is TRUE (X), then to users 4, 5, 6.
 
Problem:
Responsibility BOOLEAN FROM X TO X, (BOOLEAN = TRUE) SAP goes along.
Responsibility BOOLEAN FROM   TO X, (BOOLEAN = FALSE & BOOLEAN = TRUE, all
cases) SAP goes along.
Responsibility BOOLEAN FROM   TO  , (BOOLEAN = FALSE) SAP says 'No
Responsibilities defined'.
 
Does the responsibility has to have a value or is it possible to check on
the containerelement to be empty (in case of FALSE boolean)
 
Thanks!
