Hi guys,
I think this is an interesting feature, I expose the Environemnt to the ELContext, Then we could access current authenticatedUserId in EL, of course we need execute processEngine.setAuthenticatedUserId("johondoe"); at first.
the patch was attached to JIRA.
https://jira.jboss.org/browse/JBPM-2870
Please tell me your opinion. Thank you very much. :)
