Hi,

I'm trying to use history varaibles in jbpm 4.4 and I encounter an NPE :
2010-06-17 15:56:07,742 [INFO ] org.jbpm.pvm.internal.svc.DefaultCommandService 54  - exception while executing command org.jbpm.pvm.internal.cmd.GetHistoryVariablesCmd at 194d4313

        at org.jbpm.pvm.internal.svc.HistoryServiceImpl.getVariables(HistoryServiceImpl.java:97)

Is there something particula to configure to make it available ?

I'm using the executionService method executionService.createVariables(executionId, myVariables, true); to activate the history on the current process variable, and I can see some sql insert to the table PROCESS_HISTORY_VARIABLE so I think data are available...

Regards
