Hi to all,
while running Ch28 Customer support and after creating a ticket i got this error:

HTTP Status 500 - Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessApiUsageE xception: org.hibernate.TransientPropertyValueException: Not-null property references a transient value - transient instance must be saved before current operation : com.wrox.site.entities.Ticket.customer -> com.wrox.site.entities.UserPrincipal; nested exception is java.lang.IllegalStateException: org.hibernate.TransientPropertyValueException: Not-null property references a transient value - transient instance must be saved before current operation : com.wrox.site.entities.Ticket.customer -> com.wrox.site.entities.UserPrincipal

Someone know how to solve this?

That's very odd. I do not get this error. Can you please post the complete stacktrace(s)? Can you also post the full Java and Tomcat versions you are using, and let me know if you have updated the Maven dependency versions from those that ship in the pom file?
