"Re: java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper" To view the discussion, visit: https://community.jboss.org/message/744805#744805 -------------------------------------------------------------- Hello, I have experienced the same problem "java.lang.String cannot be cast to org.jbpm.task.utils.MarshalledContentWrapper" in jBPM version 5.3.0-SNAPSHOT. That happened in my application which uses jBPM, so it was on client side. I have switched to 5.4.0-SNAPSHOT, but now I experience a different exception. I use HornetQHTWorkItemHandler in my application. My business process contains just a simple human task in which I want to receive just one String value. In jbpm-console I can see my task waiting to be finished. I view it, fill my String value and after I confirm it, my application hangs (no exceptions) and I see the exception below in server.log: 16:10:28,984 WARNING [org.hornetq.core.protocol.core.impl.RemotingConnectionImpl] (hornetq-failure-check-thread) Connection failure has been detected: Did not receive data from /127.0.0.1:44514. It is likely the client has exited or crashed without closing its connection, or the network between the server and client has failed.
