Re: [rules-users] Calling RuleSet from a Function/Another Rule
Hi Ayon, I'm not personally familiar with Blaze, but I can tell you that in Drools, rules are not something that you "call". In Drools, rules are evaluated whenever the facts in your WorkingMemory change; and the consequences are executed according to agenda/rule-flow group, and salience settings. When the consequence of a rule introduces changes (adds a new fact, updates an existing fact, removes/retracts an existing fact) to the WorkingMemory, the rules that may be affected by that change are re-evaluated. Any new consequences are scheduled for execution, based upon the agenda/rule-flow group and/or salience settings. Any previously scheduled consequences may also be removed from the schedule, if the rule which caused them to be scheduled is no longer true. All of that said, if what you are wanting to accomplish is controlling the order of when consequences are executed then you should learn more about agendas, rule-flow groups, and salience. Otherwise, in order to cause a rule's consequences to execute, you should make sure your facts support the rule. Hope this helps, Lance Leverich ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Fully qualified name for generated classes
The issue isn't that Foo cannot be resolved, as it was imported into both
packages from the Global Area. The packages compile just fine. I believe
what might be happening, though, is that each package is creating its own
version of Foo.
For example, am I experiencing something like...
com.mypkg.a generates a class with a fully qualified name of
drools.com.mypkg.a.Foo
com.mypkg.b generates a class with a fully qualified name of
drools.com.mypkg.b.Foo
?
If this is the case, is there someway within Guvnor to refer to a
particular version? I'm beginning to think that my best option might be to
create a POJO and import it. At least that way, I can make sure I know the
fully qualified (i.e. canonical) class name.

[rules-users] Fully qualified name for generated classes
What would be the fully qualified name for a generated class, that is based
upon a fact type (for example a type named "Foo") that is defined inside a
declarative model?
How is the fully qualified name affected if the model resides in the Global
Area, and is imported into multiple packages?
The reason for my question is that I have the following issue:
In the Global Area, I have a declarative model (named MyModel) with a
definition like...
declare Foo
bar: String
version: String
end
In a package (com.mypkg.a), I have imported MyModel from the Global Area. I
have a rule like...
rule "myRuleA"
ruleflow-group "firstGroup"
when
not Foo( bar=="bar" )
then
Foo fact = new Foo();
fact.setBar("bar");
fact.setVersion("1");
insert(fact);
In another package (com.mypkg.b), I have also imported MyModel from the
Global Area. I have a rule like
rule "myRuleB"
ruleflow-group "secondGroup"
when
Foo()
then
System.out.println("got at least one Foo");
Looking at logs, the rule myRuleA fires as is appropriate; however, the
rule myRuleB does not fire, even though both ruleflow groups are
represented in the ruleflow. I have verified that both of the ruleflow
groups are activated, using the logs. My best guess at this point is that
the class generated for fact type Foo is different for each package. So,
how can I make sure that I am instantiating and checking for the same type
across packages?

[rules-users] Restricting the items included in a snapshot
I am aware of how Guvnor can be told to only include assets with a given state, during the build process. What I haven't been able to figure out is a way to tell Guvnor to only include the items that were part of the latest build, when creating a snapshot. Is there a way to do this? I am using Guvnor 5.3.5.Final. ~ Lance ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Designer for Guvnor 5.3.5
Can anyone point me to where I can find the jBPM designer tool for use within Guvnor v5.3.5? Instead of getting a download option, all we get is the error message telling us that Guvnor couldn't find the designer tool. ~ Lance ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Upgrade options and considerations
My company started out using Drools/Guvnor v5.1.1, for a single product/project. Later, we decided to start building an enterprise oriented service, which was partially completed and is based upon Drools/Guvnor v5.3.0. Recently, the decision has been made to get all of our Drools/Guvnor instances running the same version. I ran into issues (mostly related to dependencies and the use of rule-flows) when I initially attempted to just get everything running on v5.3.0. But those issues seem to have all gone away when I replaced my rule-flows with BPMN's and moved everything to a v5.3.5 instance. My question, for this group, is whether there are good reasons to move even further forward and upgrade everything to v5.4.x? If so, what might those reasons be? Are there any known, significant, issues in one or more of the 5.4 versions? Is there any consensus on which patch version of the 5.4 tree would be best? I have already been told by upper management that they would not support moving to v5.5.x, so that's not even on the table. Any feedback would be appreciated.
