This is probably caused by the history not being fully implemented. Please search the jira and vote for the respective issues.

But in the tables JBPM4_HIST_ACTINST and JBPM4_HIST_PROCINST, I can't find a way to link the sub process to its parent.
I'm facing the exact problem the same problem was also raised in another discussion: https://community.jboss.org/message/400011#400011.
I want to show the entire history path for a process and other sub processes within that process, but I have not managed to find a way of doing this properly. I see that in the JBPM4_EXECUTION table there are two columns SUPEREXEC_ and SUBPROCINST_ that seem to be set correctly during execution, but these don't exist in the JBPM4_HIST_PROCINST or JBPM4_HIST_ACTINST.
Does anyone know how to fetch the parent/child process in the history part or if this is not yet implemented? I couldn't find any jira for this, but will register one if there is no way of getting the parent/child history relation this at the moment.
