Error description

• The RESUMABLE_DASHBOARDS attribute of a Process Portal session
  is not serializable.  As a result, an error similar to the
  following is written to SystemOut.log on the server or cluster
  where the IBM_BPM_Portal application is deployed:
  
  WASSession    E SessionContextMBeanAdapter
  findAttCausingNotSerializableException
  Miscellaneous data: Attribute "RESUMABLE_DASHBOARDS" is
  declared to be serializable but is found to generate exception
  "java.io.NotSerializableException" with message
  "com.lombardisoftware.component.common.web.WebWorkflowManagerRes
  ult".  Fix the application so that the attribute
  "RESUMABLE_DASHBOARDS" is correctly serializable at runtime.
  
  This error has been observed in conjunction with the WebSphere
  Application Server session replication function (allowing a
  web session to  be persisted in a clustered network deployment
  environment, such that if the cluster member where the session
  is running fails, the session automatically resumes through
  another cluster member), but also in other scenarios where
  session replication is not being used. The attribute needs to
  be made serializable to eliminate this error.

  A session variable is not serializable, causing an exception
  to be thrown when the variable needs to be serialized, such as
  during memory to memory replication.
  

Problem conclusion

• The RESUMABLE_DASHBOARDS attribute was made serializable.
