    Exception in developerConsoleOperations.jsp after SmartGWT upgrade

    Isomorphic,

    I upgraded to SmartClient Version: v12.0p_2019-10-09/Pro Deployment (built 2019-10-09) and noticed that the following exception is now logged when opening the SmartClient Developer Console.

    The exception is only logged when running in Super Dev Mode.

    The exception is not logged with SmartClient Version: v12.0p_2019-09-14/Pro Deployment (built 2019-09-14)

    Thanks

    Code:
