In the PopUp of the CPM Portal, we added a custom button on which we perform actions: "Open Assignment" and "Run Script". As parameters, we give InteractionCall.TransferedInteractionKey, but we encounter a problem "empty assignment key" (and empty parameter for the script too). But when we verify the page InteractionCall in the clipboard, the property "TransferedInteractionKey" does have a value. Also we display that property in a field in the PopUp and it is filled.
Is there a condition on the properties we can use in the button actions?
For test purposes, we tried using as input parameter the standard Operator properties: OperatorId.pyUserIdentifier and OperatorId.pyUserName. They are both filled. But when executing the actions listed above, the OperatorId.pyUserIdentifier is recognized ==> the script is run with a filled parameter. But the OperatorId.pyUserName is not, and so the script has an empty parameter and the open assignment encouters the "empty assignment key" message.
