In the M5 release, I could use a Boolean global as an Out type parameter and changes I made to the global would be maintained in the results. In CR1, I use the CommandFactory to add the global with out set to true, and I get back the initial value of the Boolean, not the updated value. Here's a code snippet: List<Command< ? >> commands = new ArrayList<Command< ? >>(); commands.add(CommandFactory.newInsertElements(sessionFacts)); commands.add(CommandFactory.newSetGlobal("result", null, true)); Command< ? > execution = CommandFactory.newBatchExecution(commands); BatchExecutionResults results = session.execute(execution); Here's the rule that fires: rule 'Initialize' dialect 'mvel' when then drools.getWorkingMemory().setGlobal("result", new Boolean(false)); logger.debug("Initialized result to false"); end In M5, result would have a value of false. In CR1, result has a vaule of null. Am I doing something wrong with the new command structure? Is this behavior expected, or is it supposed to work like it did in M5? Thanks for any assistance.
