  • Webflow 2.3.1 with Hibernate 4 - webflow.conversation.impl.LockTimeoutException

    Hi.

    I was using spring webflow 2.3.1 with hibernate 3.6.9.FINAL and JPA 2.0.

    Everything worked well until yesterday, when i updated hibernate to version 4. Suddenly i started to get:

    Code:
    DEBUG: org.springframework.web.servlet.handler.SimpleMappingExceptionResolver - Resolving exception from handler [[FlowHandlerMapping.DefaultFlowHandler@6bea9919]]: org.springframework.webflow.conversation.impl.LockTimeoutException: Unable to acquire conversation lock after 30 seconds
    DEBUG: org.springframework.web.servlet.handler.SimpleMappingExceptionResolver - Resolving to default view 'uncaughtException' for exception of type [org.springframework.webflow.conversation.impl.LockTimeoutException]
    DEBUG: org.springframework.web.servlet.handler.SimpleMappingExceptionResolver - Exposing Exception as model attribute 'exception'
    DEBUG: org.springframework.web.servlet.DispatcherServlet - Handler execution resulted in exception - forwarding to resolved error view: ModelAndView: reference to view with name 'uncaughtException'; model is {exception=org.springframework.webflow.conversation.impl.LockTimeoutException: Unable to acquire conversation lock after 30 seconds}

    Does anyone knows what could be the cause of this problem?

    Thanks in advance

    Best regards
