I'm have some problems with IRF and both "static" and dynamic pulldowns (Select Form Element) in the same UIF/IRF.
To become familar with the dynamic pulldowns i took the "09 Populate Dropdown Array" from the PAM_PreDefindedContent - User Interactive Form" Library and made a copy to my test folder.
I modified the process to get LDAP users (instead of the sample operator), started the Process and - Perfect! - i had a dropdown list of all ActiveDirectory displayNames in the dropdown "Select" (first Image below).
So i did take this "knowledge" to my existing User Interaction Form "Kein-Notfall-Change-IRF-A-AD to add the possiblity to select the appropriate Employee (add the LDAP Operator to the process "Kein-Notfall-Change" and extended the UIF/IRF. But bad news, in the existing IRF the dynamic dropdown does not work (Second Image below). I'm confused.
I exported the "sample dropdown..." and my Process with the IRF's - see in the zip file.
The 3rd image shows the ldap-operator and the 4th image shows the related IRF Operator in the "Kein-Notfall-Change" Process.
