[opencms-dev] defining process in jBPM-OpenCms?

Hello Shi:
There are two things am working on, and I need your help in this regard:))
Firstly, I made a copy of your publish process sample and changed: process
name, assinged new opencms user to editor and finally assinged "Draft Doc"
task to that new user (editor). Build and deployed in opencms, it works
fine, while forwarding the "Draft Doc" task to the newly assinged opencms
user.
I notice that, since it is a document publishing process, which starts
with selecting "ready-made" document present in opencms repository and then
it it forwarded for draft doc, recview doc and finaly publishing document.
However, if the document is changed/modified in between on any task-node,
the changes get reflect on the document present in opencms repository.
Whereas, as per my understanding of document publishing process, the changed
should not reflect to original doc in opencms repository untill unless the
document is finally published through publishing process. And this is
something which I am looking for. How it could be done? Any insights?
2nd thing is that: I created a new process (myProcess) project in eclipse,
deployed their in jboss and examined/run from jbpm-console. Then I tried
migrating same process under "OpenCms-7.0.2-jBPM-3.1.2/processes directory
in eclipse. I created a classes folder in which I placed .class files, and
placed gpd.xml, processdefinition.xml and processimage.jpg in
OpenCms-7.0.2-jBPM-3.1.2/processes/myProcess. Build .myProcess.process and
successfully deployed/uploaded to jbpm-Workflow in opencms. But after
clicking "new workflow" in admin console, I got NullPointerException. My
question, what is the right approach of migrating JPDL process created
in eclipse into your plug-in that is, OpenCms-7.0.2-jBPM-3.1.2/processes in
eclipse?
Looking forward for your reply.
Bye,
Viki.
