Using the upload process function of the jbpm-console web app, deploy two processes with a parent-child relationship through a process-state node:

1. childprocess.par

<process-definition name="child">
[...]
</process-definition>

2. parentprocess.par

<process-definition name="parent">
[...]
<process-state name="process-state1">
<sub-process name="child" />
<transition to="end"></transition>
</process-state>
[...]
</process-definition>

After the two processes are deployed, the relation from the parent-process to the child-process is not properly set in the database:

mysql> select ID_, NAME_, SUBPROCNAME_, SUBPROCESSDEFINITION_ from JBPM_NODE where CLASS_ = 'C';
----------------------------------------------------+

----------------------------------------------------+

----------------------------------------------------+
1 row in set (0.00 sec)

This is due to the fact that the jbpm4jsf part initializes the JbpmContext after the processdefinition.xml file is parsed, therefore the call to DbSubProcessResolver.findSubProcess returns null.
