问题
I have a grails app doing some stuff in the right way with webflow. So everything goes right in development mode, i can finish the registration and objects are serialized normally. But then, in production mode, deployed on a tomcat 7 with ssl, the following error appears when it's time to persist datas. In a nutshell the serialization don't work. Please help, i have no idea at the moment. The only difference of configuration is that i force https with spring security in production.

UPDATE
It looks like the problem could be related to the following JIRA issue.
Please try the workaround mentioned in the issue comments.
If your command/domain object used in your form doesn't implement serializable such an error will be displayed.
Make sure that ALL objects(domain, commands, model objects) involved in the flow scope (your wizard with webflow) implement serializable.

There is an open jira ticket for that: http://jira.grails.org/browse/GPWEBFLOW-85
