Ruleflow nog showing
by Femke De Backere
Hi!
As I was creating a new ruleflow, to fit as a subprocess in another
ruleflow, I encountered the following problem: My ruleflow is build,
and I checked the correctness with the "Check the ruleflow model"
button. When I close Eclipse and reopen my project again, my whole
ruleflow (except for the start node) is gone, the xml behind the .rf
still exists, but the view is gone. Has anyone any clue what happened?
Thx,
Femke

Creating fact instance programatically
by nestabur
Hi all,
I'm trying to create a fact programatically like this:
FactType myfact =package.getFactType(factTypeName);
Object myPojo = myfact.newInstance();
An error occurs when calling the method getFactType, here my stackTrace:
36267-1236185246849-0:0:1:1 Exception while processing message:
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
java.lang.StringIndexOutOfBoundsException: String index out of range: -1
at java.lang.String.substring(String.java:1938)
at java.lang.String.substring(String.java:1905)
at org.drools.rule.Package.getFactType(Package.java:552)
My drools version is 5.0.0.M5
Any suggestion?

Events - Determining the Fact Pattern
by David Boaz
Hi all,
Is it possible to determine the Pattern that ‘produced’ a given Fact? For
example, assuming we have the following rule and event handler:
rule r1
when
p1:Person(...)
p2:Person(...)
then
...
end
protected class MyAgendaEventHandler extends
DefaultAgendaEventListener {
@Override
public void
afterActivationFired(org.drools.event.rule.AfterActivationFiredEvent event)
{
String ruleName = event.getActivation().getRule().getName();
KnowledgeRuntime knowledgeRuntime = event.getKnowledgeRuntime();
for (FactHandle factHandle : event.getActivation().getFactHandles()) {
Object fact = knowledgeRuntime.getObject(factHandle);
Pattern pattern= ?;
}
}
}
Is it possible to determine the Pattern that originate a Person object? If
yes, how the pattern is identified?
Thanks, David

drools-solver -- logger error (slf4j binding)?
by Andrew Waterman
Hi,
I'm using the drools-solver.M5 build through Maven and have gotten the
following error while running my project:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for
further details.
I've checked my dependency graph, and drools-solver references the
sl4j-api, but no implementation. I checked the mvnrepository, and
there are several other slf4j related projects. What is the preferred
binding for JDK1.6?
best wishes,
Andrew

Using "matches" in Guided Rule Editor (BRL)
by Andrea H.
Dear all,
I have a problem when using the operator "matches" in the Guided Rule
Editor.
I can use the operator from the drop down list, but when saving the rule,
the tabs "BRL Source" and "Generated DRL" show me that the operator has not
been used at all. Instead, the "operator" tag is left out completely in the
BRL source.
If I choose a different operator, e.g. "is equal to", save, and switch back
to "matches" (and save again), than the BRL source still shows the operator
"==".
If I however edit the BRL source itself to contain "matches", the rule works
fine in my application.
Strange enough, if I use "and matches" in a multi-part-condition on one
attribute, there does not seem to be this problem (the BRL says "&&
matches"). It seems to be only a problem if the "matches" operator comes in
the first assertion line for an attribute.
I would be really grateful if anyone had an idea on this behaviour, since I
seem to be quite lost!
Thanks in advance,
Andrea

Re: rules-users Digest, Vol 28, Issue 19
by Ricardo Gil Alcañiz
Thanks for your fast response Kris and Michal!
I tried to use your solution Kris, but I've found that 5.0.0 M5
WorkflowProcessInstance does not seems to provide getVariable method. I've
found that method into WorkflowProcessInstanceImpl searching in svn trunk. I
must work with that class or I missed something? Thanks again!
Ricardo.
