In the first Activity of one of my Processes I have an Activity Dialog that includes CustomerID, Priority and a few other dynamic fields. I am trying to restrict the value of one of these dynamic dropdown fields as follows: --- - ChangeBy: *** ChangeTime: *** Comment: '' ConfigChange: Possible: Ticket: DynamicField_SubmittedBy: - Customer ConfigMatch: Properties: Frontend: Action: - CustomerTicketProcess CreateBy: *** CreateTime: *** Description: For CustomerTicketProcess Action, limit options for Submitted by dropdown. ID: *** Name: ALL-Processes-CustomerTicketProcess-Possible-SubmittedBy StopAfterMatch: 0 ValidID: '1' When I first open the Dialog in the Customer UI everything works as expected. "Customer" is the only possible value for the "Submitted by" dropdown. However, if I enter a value for CustomerID, or change the value of Priority, or another dynamic dropdown field, all values for "Submitted by" become available. I have other ACLs restricting dynamic dropdown field values that work fine, the issue seems to be with using the CustomerTicketProcess Action as a match property. I've also confirmed the same problem behavior with AgentTicketProcess.
