I understand that if I call setGlobal on a stateful session, this global value will be shared for all simultaneous calls to executeRules across all threads. I'm looking into CommandFactory, which has a newSetGlobal method. From what I gather, a global set via CommandFactory.newSetGlobal and then executed with a call to execute(CommandFactory.newBatchExecution(cmds)) would be scoped solely to that execution, regardless of it is a StatefulKnowledgeSession and there are other parallel command executions against the same session. Can anyone confirm if that is accurate? Thanks in advance, -- Ricardo J. M?ndez http://www.arquetipos.co.cr/ -------------- next part -------------- An HTML attachment was scrubbed...
