Re: com.google.gwt.user.client.rpc.SerializationException

Hi All,

Thanks for your response. I changed the exception class as suggested.
It now implements Serializable interface and now that error has gone.
But still I get this error which is kind of vague.
com.google.gwt.user.server.rpc.UnexpectedException: Service method
'public abstract java.util.List
org.finra.aep.client.AdminService.getFirmNames() throws
org.finra.aep.shared.ServiceException' threw an unexpected exception:
java.lang.IllegalArgumentException: node to traverse cannot be null!
