Session Serialization

I've encountered a problem when integrating Activiti. Before using session persistence, that worked. Now we are using session persistence. But it seems activiti can not work in such scenario. I get serialization exception all the time.

My Activit version is 5.15.1.

I will attach my configuration file.

I have spent a lot of time on this. I've ever tried not to persist ExplorerApp object, but it will cause not working.

I figured out the exception step by step but I'm afraid I've got to the end of the dead road.

It keeps showing this exception:

java.io.NotSerializableException: org.activiti.engine.impl.form.BooleanFormType


I don't know how to persist it.

Can you help me ?

That's an issue indeed. Could you raise a JIRA issue for this?

Thanks,
