This is not an answer to your question, but rather asking the same question
with a slight twist:
I'm in the middle of trying to see if I can shift from stateful to stateless in
my project and the "session.getObjects" method is what we would use in stateful
as well to read back all of the new objects created during rules execution. My
project seems to be much more geared towards stateless and thus far testing has
shown our time would benefit significantly from the change.
I see in the docs where ExecutionResults are used with the execute:
ExecutionResults results =
ksession.execute(CommandFactory.newBatchExecution( cmds) );
But even within results I do not see how to gather my objects from memory.
Any thoughts on what I am missing here?
Thanks
Dean

Subject: [rules-users] Use of StatelessKnowledgeSession
Hi there
I was wondering if someone might be able to help with what I am trying to do.
I have the following rule definition:
rule "open work item"
when
Task ( status == "OPEN")
then
insert(new Action("Take","take_task"));
insert(new Action("Complete","complete_task"));
insert(new Action("Close","close_task"));
end
Basically I want to insert a Task and then get back a list of Actions that are
available for the Task (based on the status. I have this working with a
statefulknowledgesession with the code:
List<Command> commands = new ArrayList<Command>();
for (Task task : tasks) {
commands.add(CommandFactory.newInsert(task));
}
session.execute(CommandFactory.newBatchExecution(commands));
session.fireAllRules();
session.dispose();
//this returns the actions
Collection objects = session.getObjects(new
ClassObjectFilter(Action.class));
I was wondering whether it is possible to do this with a
statelessknowledgesession instead? I could'nt see how to achieve this without
updating the task to include the actions.
Any help would be appreciated.
Cheers
