How to persist data object in JBPM 7.9

I'm now trying to use the new jbpm 7.9. I have a problem that my custom data object is not saved in my database. Below are my steps:

  1. Create a persistable data object
  2. Create a simple process which used the data object as a process variable
  3. Modify the project settings Persistence section.
    1. Change to a datasouce, mysql, already defined in the app server.
    2. Add the data object to "Project Persistable Data Objects"
    3. Change the dialect to org.hibernate.dialect.MySQL5InnoDBDialect
  4. Deploy to one kie server.
  5. Start a process instance either by UI or rest API. It completes successfully and I can see the variable is created correctly in the process manager UI.

But after I check the database, there's neither the table nor my record. Do I make something wrong? The seetings

Well, I find the answer by myself.

I need to define additional marshalling strategy

<marshalling-strategy>
            <resolver>mvel</resolver>
            <identifier>new org.drools.persistence.jpa.marshaller.JPAPlaceholderResolverStrategy("com.myteam:xerox:1.0.0", classLoader)</identifier>
            <parameters/>
</marshalling-strategy>

This is not mentioned in the document anywhere. :(
