jbpm @CreateProcess with custom object going into process in

[js8523]

Hi All

Is it possible to placing a custom object (e.g. @Entity class UserDefined { }object) into the process instance, for the next stage in the process to pick up and work on.

All the examples in Seam store the object in persistence and pass a reference to the object through the process instance, is it possible to just pass the object through the process instance as I don't want to place the object in the database untill I have done at least the second step in the process.

I get this stack trace when I try to do this via:

@Out(scope=ScopeType.PROCESS)
private Contact contact;

Hi All

A little update.. I have investigated this problem further, and it is unrelated to the variables "outjected" into the process instance. The problem is actually with the lookup of the ManagedJBpmSession (whilst invoking the @CreateProcess.

The jbpm session it retrieves is null.

I've got the startup listener as per the dvd store (with the process xml def changed). This works, I see the output on deploy. I've checked the jndi view and the jbpmsessionfactory is bound, but when the invoker hoes to fetch it, it returns a null session.

Any help, anyone.

I've deployed the dvd.ear and it works perfectly. I've tried using the exact same jars but still the same error. I am currently using jbpm 3.0.1 and jboss seam from cvs.

Many thanks,

James
