Rob,

ProcessInstance.hbm.xml in head has already been modified to relax the uniqueness constraint.

I don't know what the plans are in this area... I vaguely remember some forum mail leading to relaxation of the constraint. You might want to try to dig it up... however, I can't find it, so I might be dreaming.

Hello,
i'am getting an error always when i try to start a new instance of a process definition containing a sub-process:

Error starting process: An exception of type "org.jbpm.JbpmException" was thrown. The message is: can't create a process instance when processDefinition is null

I have something like this:
<process-state name="sample">
<sub-process name='targetNameFile' />

I'am doing something wrong?

Thanks

do you have a sub processresolver in your jbpm config?

I dont think so.

Where can i look for it?

Thanks
