Re: [rules-users] Protobuf Marshaller Question (ScheduledActivation Persistence)
Dear developers,
Unfortunately, I was not able to solve this problem yet. However, I
found another issue that seems to be related.
More precisely, when I try to delete the rules that led to the
ScheduledActivations (which are not fired after unmarshalling, i.e.,
there are "orphan" activations on the agenda) I get the following
trace:
java.lang.NullPointerException
at org.drools.time.impl.JDKTimerService.removeJob(JDKTimerService.java:134)

Obviously, there is still a connection between the unfired activations
and the rule.
Since some time ago I've successfully used the JPAKnowledgeService, I
looked into the code and found a line in initKSession which looks
promising:
((AcceptsTimerJobFactoryManager) ((InternalKnowledgeRuntime)
ksession).getTimerService()).getTimerJobFactoryManager().setCommandService(
this );
I kindly wanted to ask, if somebody can explain the implications of
this codeline with regards to the ScheduledActivations.
I would be still happy, if someone could help me.
Thanks,
Philipp

Alright, one step further.
I retrieved the current agenda via
InternalAgenda agenda = ((AgendaImpl)session.getAgenda()).getAgenda();
before marshalling and after unmarshalling.
Now its great, all my example ScheduledActivations are successfully
unmarshalled to the agenda. However, they are not fired for some
reason?
I call fireAllRules after recreating the session.
Sorry for spaming but I hope this helps someone to get me into the
right direction.
Thanks again,
Philipp

Maybe one addition to that. Currently I am working on 5.4.0.CR1 but
same applies to me for all versions until 5.3.2.Final including
5.4.0.Final (since obviously the protobuf impl has been introduced in
5.3.2).
Thanks again,
