rules update not working properly .
by sony.john＠kie.com.sg
Hi All,
When i try to update three object in rules its changes the values in
rules . But after update its not reflecting on my calling code. But
workflowAction object has been updated.
What could be the problem anything i missed out here.
Please help me .
rule "Referback"
when
$workflow : Workflow(workflowActorId==2)
$workflowactor : WorkflowActor( $actoremail :actorEmail )
$workflowaction : WorkflowActions(currentUser==$actoremail &&
actions=='referback', $prevActions : prevActions )
$workflowactor1 : WorkflowActor( actorId== 1 && actorSign!=null)
then
System.out.println("drl2 action finally " + $workflowaction.getActions() +
$actoremail +$workflowactor1.getActorEmail() + $prevActions +
$workflow.getWorkflowActorId()
);
$workflow.setWorkflowActorId(1);
$workflowactor1.setActorSign(null);
$workflowaction.setActions("not need further actions");
System.out.println("worklfow id " + $workflow.getWorkflowActorId() +
$workflowactor1.getActorId() + " " + $workflowactor1.getActorSign());
update($workflowactor1);
update($workflowaction);
update($workflow);
end
Thanks in advance

Drools Flow inconsistancies
by paulB
Hello,
I'm hoping someone can shed some light on something that I have limited info
to provide. This is a shot in the dark...
I have several processes that I have created with many different work item
implementations that I've created. They all work wonderfully...or they did.
Suddenly, I'm having some odd behavior on my servers.
1. Some processes (only some, not all) suddenly will not map result values
into the process variables on completion.
2. Any onEntry or onExit actions "crash" (I know that's a vague term) the
process.
3. Splits seem to randomly choose the resulting path.
I've spent three days on this doing the stare-and-compare to no avail. When
I attempt to debug these processes in Eclipse, everything runs perfectly.
My first thought is that I was not including the correct jars on my servers.
This still may be the case, but I was hoping someone knew something I
didn't.
Thanks in advance for any help,
Paul

NoClassDefFoundError when inserting Guvnor-declared Fact
by John Peterson
I'm experiencing a stack trace error (which I've pasted below) with a
sample Drools/Guvnor application. I'm running version 5.0.1 right now.
Here's the scenario:
I have a Java application loading data (56 records right now) from a
flat file, creating objects (one per row), parsing the individual fields
on the file into the attributes of the objects, putting them into an
array, and then inserting them into my Guvnor session. In Guvnor, I
have a POJO model to receive the data plus a Declarative Model that
enables the Guvnor user to set derived values based on the input data.
There is a very basic rule that says the following (using the Guided
Editor):
When
AppData[ad]
Then
System.out.println("Creating DerivedValues for " +
ad.getAwards_id()); /* Added as Free Form DRL
Insert DerivedValues appID=ad.getAwards_ID();
System.out.println("DerivedValus for Awards_id " + dv.getAwardsID()); /*
Added as Free Form DRL
Essentially, for each Fact of AppData, I'm creating and linking it to a
Fact of DerivedValues that the user can add attributes to. I runs fine
for the first 51 rows, then blows up on the rule when it is processing
the 52 row (with 4 more to go after that). If I cut the file down to
only have 51 rows, it doesn't blow up. The error -
java.lang.NoClassDefFoundError: com/statefarm/DerivedValues is confusing
because it has used DerivedValues 51 times without issue up to this
point. I've been trying to a handle on this for a couple days without
any luck.
Here is my stack trace:

It's similar to JBRULES-2230. I reused solution from comments (on

patch. Can somebody apply to TRUNK?

counting facts of a kind
by Wolfgang Laun
As simple as it gets:
rule countHigh
when
$n : Number() from accumulate ( $sgc : StartGoalConn() count( $sgc ) )
then
System.out.println( "plain routes: " + $n );
end
And yet, it fails:
Exception in thread "main" org.drools.RuntimeDroolsException:
java.lang.ClassCastException: rss.ixl.route.TrainStartGoalConn cannot be
cast to java.io.Serializable
Sure, adding "implements Serializable" to StartGoalConn fixes this. But why
is this necessary?
FYI, StartGoalConn is abstract superclass of TrainStartGoalConn - just in
case this has some bearing on this issue.

Rules in Database.
by tom ska
Hi,
what I can't do is to save rules defined in Guvnor to DBMS's tables. I want
another application to read rules, and this another application can read
from Database. I saved Guvnor's data in database, but I can't see tables
with rules definition... How can I do it?
Thanks in advance,
tom.

Error while applying changeset in 5.1 version
by Swapnil Sawant
Hi,
I have used 5.1 drools-api and drools-core JARs and wrote following code :
String currentWorkingDirectory = System.getProperty("ofbiz.home");
kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyRuleAgent"

String url =
"file:"+currentWorkingDirectory+"/framework/drools/config/changeset.xml";
System.out.println("Url is "+url+"\t CwD
"+currentWorkingDirectory);
kagent.applyChangeSet( ResourceFactory.newUrlResource( url ) );
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add( ResourceFactory.newUrlResource( url ),
ResourceType.CHANGE_SET );
kbase = kagent.getKnowledgeBase();
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();

Then I check drools-core.jar in version 5 and in 5.1 too.

was present in 5.0 version but was not there in 5.1 .
Pl help me in resolving this issue.
Thanks,

Stream Mode with Temporal Reasoning and Event Lifecycle Management
by Tina Vießmann
Hi,
I'm thinking about something. Maybe anyone can tell me.
The Stream Processing Mode of Drools Fusion provides automatic lifecycle
managment. For my understandings this is based on the sliding windows
used inside the rule conditions, the @expires metadata and the @delay
metadata. Am I right so far?
My questions is now: How are Events handled if non of the things listed
above are used?
Let's say I've got rules just using the temporal reasoning operators
inside the rule conditions - no sliding windows at all. I'm also not
using any of the @expires and @delay metadata. Is it correct than that:
- Drools matches the event coming in and the events existing in the
KnowledgeBase and eventually activates a rule. And after fireAllRules()
is called the resulting actions are performed and all Events are
retracted by the automatic lifecycle managment, because there are no
hints (like a sliding window) that events will be needed again. (So that
the knowledge base would be empty again?)
Thanks for any explanations. :)
