I tried to delete the implementation of Serializable in my BaseModel,
but still there is an error in my log file. The log error
ERROR [main] ManagerBase.start(638) | Exception loading
sessions from persistent storage
java.lang.NullPointerException
only occurs when I turn off tomcat then restart it again and refresh my
page. the variable Study.name became null but before I restarted it has
a value? How does this error occurs?
Thanks,
Adriel
