Mark,
Thanks for your help! I was finally able to test, and that totally worked. I was confused by example 3.37 (4.37 in the Drools 5.2.0 docs). The key point I missed must be that newStartProcess causes all the rules to fire. Well, at least I was right about it being something simple. :-)
Best,
Hank

Aha! I missed the line about the dispose. That makes a lot
of sense. What I don't understand is why the example 3.37 in
the docs would work. If I understand what you're saying, it
shouldn't.
It should work, as long as the query is executed as part of the
same execute batch. We have unit tests f or that too somewhere.
ok I see the problem. Your rules will not fire until the all the
command shave been executed. i.e. the implicit fireAllRules() is
once all commands have been executed. Which means the query will be
invoked before your rule fires to insert the object.
Instead you need to add the FireAllRules command before executing
the query.

Thanks!

StatelessKnowledgeSession.execute(...) executes the
command(s) and
finally calls dispose() on the
session. Use a stateful session or a global (filled with a
low-salience rule) or - simply use the getObjects command.

Hi all,
I'm new to Drools, so please excuse me if I'm asking
about the obvious--it's certainly not obvious to me. The
problem is this: I use a stateless knowledge session
where a list of facts is inserted. The rules that fire
create new facts, and after all the rules have fired,
I'd like to obtain a list of all the facts (the old and
the new). The best way seemed to use a query. I'm using
Drools 5.1 on Linux.
The logger shows me that the BadgeState object is
created, but the query returns an empty list. I've
searched the documentation, which suggests that I'm
doing it right (http://drools.herod.net/drools-expert/html/ch03.html#d0e1956,
example 3.37), the archives of this mailinglist, and the
web, so far without success.
Clearly, I'm missing something, and I have the nagging
feeling that it's something simple...
Any help is much appreciated!
Best,
Hank
