This Knowledgebase article describes a known issue that occurs when entering text into a Java driven Graphical User Interface.
When entering text into a Neverfail Heartbeat Configuration screen, the text may be not entered correctly.
This behavior can happen with any Neverfail Heartbeat GUI and in fact any Java driven GUI. For example, within the Server Configuration wizard, when entering a valid IP address for the Secondary server, simply clicking the Finish button after entering the IP information is not sufficient. Once the IP address has been entered you must also press the Enter key for the IP address to be stored in the configuration.
Similar behavior can occur throughout Neverfail Heartbeat GUIs. Care should be taken at all times when entering important configuration information.
