Hi Lucas,
Thanks for your replay. And one more question I have is,
Can we have access to TimesTen or any other in-memory databases so
that no need to load WorkingMemoryEntryPoints with all the objects?
Is there any way to load objects into WorkingMemoryEntryPoint
Hello-
We are writing rules against complex objects (derived from XML) that contain
nested arrays, notionally like this:
Record {
Detail[] recordDetails;
}
Detail {
Activity[] yearlyActivity;
}
Activity {
int year;
}
Is it really true that I must use a "from" clause to navigate the hier
To make myself clear, here is the difference I copy and paste in a picture.

Thank you kris,
Removing persistance-api.jar from the gwt-console-server-drools.war helped
to remove the error. Now I'm able to view the process on web-console.
However, when I'm clicking on Start under Process Instances, the following
error occurs. Can you please suggest how can I solve this. I'
I am using Drools-core.jar(version-5.0.0.CR1) and getting the following
exception. I could see similar stacktrace reported with
JIRA-1888(https://jira.jboss.org/jira/browse/JBRULES-1888) and its marked as
closed. Fix related to this Jira is not available (Rete.java) in the Drools
5.0.1 and 5.1.0
create declared types and then use a transformation tool to marshal
those maps into the internal type declarations. You can look at the
pipeline's jaxb and xstream for examples of how this works.

That facts are coded in java is incidental there use is st
The basic behaviour of the engine is to re-evaluate all rules where a
new, updated or deleted fact is referenced via its (sub)class or some
interface name. If the LHS is true, the rule is fired.
To insert a complex fact requiring setter calls, make sure to do the
insert() after all the settings.
Hi,
the best way is use DSL because isn't possible create "complex" rules

Can you exclude this or a similar scenario, where Parameters are added

Kris,
Many thanks for your continued help. I updated to the latest trunk, and
replaced my milestone node with a state node as suggested, and the process
instance completed as required.
Two things I noticed:
1. The state node isn't currently available in the palette of the Eclipse

Hi Kris,
Thanks for your reply.
This problem was solved. It was because I was not completing the workItem
using the kession object. Because of that I was getting NPE in
JPAWorkItemManager.java
After that when I made changes to my code I got the same exception but
this time it is in MarshallerRe
Thanks for answering,
Further detail:
The actual output is the rule is fired (ie, the param is not found) and then
the param is printed out. So, in fact, the param does exists.
The Task is created as usual, nothing special here (insert (new Task...)
