I use many valuelists which are setup with: application.SetValueListItems.
In NG Client I have experienced that after some Idle time of the client (without logout) the valuelist is empty. In the field the real-value is shown and the valuelist in the combobox is empty. Hard-coded valuelist with custom values don't have any problems after Idle time of the client.
Has it anything to do with: sablo.window.timeout.secs ? I have the value on 1800 seconds.
