Complicated Issue
by abhinay_agarwal
hey,
M using guvnor 5.3.0 Final version and two instances of guvnor.
In my first guvnor application, i ve two packages containg all my rules
which i am accessing using drools core and knowledge api v5.2.0 Final .I use
type "DRL" to extract rules from my change set.
In my second guvnor application, i just have a package which contains my
JBPM process. Here, i am using drools 5.3.1 Final jars to connect and make
my kbase. i use type = "PKG" in my chnage set, which is contradictory to
JIRA <https://issues.jboss.org/browse/JBRULES-3388> is opened that a PKG
cannot be read, but was working fine for my application.
Now i dont want to deploy two different wars of guvnor and was expecting to
do it by deploying just 1 guvnor.
So instead of taking the headache of using different jars, i used a neutral
GUVNOR and drools 5.4.0 final version. I deployed the guvnor, imported the
old repository, built the packages and tried firing the rules using type =
"DRL" in my change set. Everything Worked fine.
As soon as i changed my type = "PKG" in my change set to access the rules, i
got an error :

Rules with variable timers
by Shannon Hastings
Is there a way to write a rule in DRL that uses a timer or something that is dynamic. I.E. I want the time that rule waits to fire to be dependent on a variable such as below:
rule "CheckDoseMissed"
no-loop
timer(int: $eventA.sleepTime)
when
$eventA : MyEvent()
………..

You'll need to specify the planningVariableName, see the
curriculumCourseSolverConfig.xml for an example how to do that.
This is because there are 2 planning variables, it's independent of whether
or not some of them are chained.

java.lang.LinkageError, but only sometimes
by kennywest
Dear list,
We have an application (A) deployed on JBoss 7.1.1 accepting commands (CQRS,
but only C and Q :) ). A console application (B) is sending a large volume
of commands to create entities in A. Entities in A are validated by Drools
(plain drl files, configured in spring using drools-spring). Most of the
time this works just fine. But sometimes, we get the following exception:
java.lang.LinkageError: loader (instance of
org/drools/rule/JavaDialectRuntimeData$PackageClassLoader): attempted

Any idea where this is coming from or what's causing this.
We are using:
- JBoss 7.1.1
- drools 5.4.0.Final
- jdk 1.6u30
- Windows 7 64 bit
regards,
Kenneth

Problem sharing declarative model between two packages
by Al
I would like to be able to share a declarative model between two packages.
When I attempt to do this by creating my model in Guvnor's Global Area and
then importing it into each package, I find that instances of the declared
types that are created by rules in one package are not recognized by rules
in the other package.
For example, suppose I create a model in the global area with a declared
type:
declare MyType
field1: String
end
I then import this model into packages "p1" and "p2". I add the following
rule into package "p1":
rule "create it"
when
eval(true)
then
MyType m = new MyType();
insert(m);
end
and I add the following rule into package "p2":
rule "find it"
when
$m : MyType()
then
System.out.println("found it");
end
At runtime, the "create it" rule fires and inserts a "MyType" object.
However, the "find it" rule never fires.
If I add a WorkingMemoryEventListener and look at exactly what is being
inserted, I can see that the "create it" rule is inserting an instance of
p1.MyType. I assume that the "find it" rule is looking for an instance of
p2.MyType and that is why it never fires.
Is there a different way to accomplish this? Or, are declarative models
simply not intended to be shared across packages?

Custom Form with DSL
by bhochhi
I were able to launch the custom form in DSL, however the rule condition is
not mapped to corresponding DRL. I don't know if this is a bug or just
something is missing. my DSL mapping looks like this:
[when]
my dsl is "{varName:CF:MyFactType.fieldName}" =
System.out.println("{varName}")
I have working set created then configured custom form for fieldName. All
things working but rule is not validating. When I check drl source, I found
the mapping is not taking place, its still displaying DSL expression in DRL
source instead of displaying:
System.out.println("values from cf")
Any ideas? I have tried this in guvnor 5.4.0.final and 5.5.beta1
