Symptoms

MetaSolv Solution version 6.3.0.b555 running with ASR 54.0.0.b24 and ASR 55.0.0.b84

When attempting to open an ASR order (ASOG version 53), the application displays a blank white screen in the area where the order is expected to open. A "Servlet failed with an Exception" for "java.lang.NullPointerException" is thrown in the mslv01.mss.log. Attempting to refresh the blank white page using CTRL+Right-click > Refresh, displays an "Error 500--Internal Server Error" message. No errors are logged in either of the appserverlog_ASR{VERSION}.xml log files (appserverlog_ASR54.xml and appserverlog_ASR55.xml). Also, the health state of both deployed ASR applications are reported as OK when viewed in the Oracle WebLogic Server Administration Console.
