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]

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