Re: [rules-users] Fill dependent dropdown lists based on a web decision table

[peach_wyss]

ok thanks, all is much clearer now...

What I don't understand:
- When I see examples of enumerations in guvnor like:
'Car.color' : ['red', 'blue','green']

-> In all of this examples, there seems to be a text editor in guvnor. But when 
I create a new enumeration in guvnor (5.5. final), there isn't a text editor. 
What I see are three text-fields ("Fact", "Field", 'Context'), which I don't 
understand. Is there a way, to switch to the text editor view?

Sorry, maybe this is a stupid question, but couldn't really find a description 
of this in the web.

Thanks for your help.

Kind regards,
Peter

Did you read the "Advanced" section?

This talks about how you can use an external source of data for enumerations in 
Guvnor.

I thought this is what you wanted?

[arul.prasha...@gmail.com]

I have the below rules written but $xyz isn't available or visible in Rule 2.
Is this the way extends keyword works?

rule "test 1"
when 
$xyz : XYZ(value == 0);
then
// do somethings

rule "test 2" extends "test 1"
when
 eval($xyz.reference == 1)
then
 // do something.

Exception:

Error: unable to resolve method using strict-mode: java.lang.Object.$xyz()

Re: [rules-users] Tree iteration with accumulate: is it possible ?

[Davide Sottara]

The not-so-immediate solution would be to use queries,
for example something along the following lines:

declare Node
  id : String
  children : Node[]
  value : Integer
end

rule "Init"
when
then
  Node n1 = new Node( "l1", new Node[] {}, 10 );
  Node n2 = new Node( "l2", new Node[] {}, 7 );
  Node n3 = new Node( "l3", new Node[] {}, 9 );

  Node x1 = new Node( "x1", new Node[] { n1, n2 }, -1 );
  Node x2 = new Node( "x2", new Node[] { n3 }, -2 );

  Node rt = new Node( "00", new Node[] { x1, x2 }, -3 );

  insert( n1 );
  insert( n2 );
  insert( n3 );
  insert( x1 );
  insert( x2 );
  insert( rt );
end


query score( Node $node, Integer $score )
  // either the node is a leaf, so just return its value
  $node := Node( children.length == 0, $score := value )

  or
 
  ( // or it is not, so let's pick the children
$node := Node( $children : children, $sz : children.length > 0, $val
: value )
and
  accumulate (
  // for each child...
  $child : Node( this memberOf $children ) 
  and 
  // ... calculate the partial child's score recursively
  score( $child, $x ; ),
  // sum all the partial scores
  $tot : sum( $x ) 
)
and
// add the local parent value and return
$score := Integer() from $tot.intValue() + $val
  ) 
end

rule "Check"
when
  $n : Node()
  score( $n, $x ; )
then
  System.out.println( "Query-ed value from node " + $n + " >>> " + $x );
end


In the last rule, you can replace $x with a literal (also remove it from
the printout) :
score( $n, 20 ; )
and the rule will fire only for those nodes whose "deep sum" is 20

[kurrent93]

When can expect Drools 6 to make it into Enterprise support?

I understand this is a long way off, but generally, is this 1 year,
18months, or longer?

Re: [rules-users] How to integrate Declarative Fact created using Guvnor in Java

[IPatel]

I was able to fix the problem but now I am with more questions then answers.

Here is what i had before defined in my DSL

[when] The transcation is zero dollar = trans:Transcation (Indicator == "N")


[when] System description one field is ABC= $trans1:Filter(Field1 == "ABC")
[then] Filter out the records = Transcation trans2 = new Transcation();
trans2.setFilterOutRecords( true );insert(trans2)

Now in the business rules i created following rules
Rule 1:
When
The transcation is zero dollar
Then
 Filter out the records

Rule2:
When
System description one field is ABC
Then
Filter out the records

Both test cases are passing in guvnor

However when i fire these rules using Java, i was not able to get expected
results.

This is how i fixed it.

For each When defined in DSL i have appropriate Then. 

So the question is can we not have a generic Then statement where i can set
a value of the field and then use that with When condition as appropriate.

Your help will be appreciated?

Re: [rules-users] Drools / Guvnor 6

[Mark Proctor]

6.0 stuff is still raw, there are alphas, but they are not really got general 
use. We'll put out a beta shortly, I'd recommend you wait until then.

Also a lot has changed in 6.0, especially around deployment, so it won't be an 
easy switch.

[Wolfgang Laun]

I think that the simplest solution would be to either store the sum of
the children's values into each Node, or to create and insert
additional facts containing these sums, in parallel to non-leaf Node
facts.

[rules-users] constraints lacking and in excess

[Michiel Vermandel]

Hi,

I have written a custom move implementation.
At first I got the exception:

java.lang.IllegalStateException: The moveClass (class 
my.planner.solver.MoveGroupToPeriod)'s move (PROJECT Period GroupChange:{T= 
Inspect 55871.I#0 [4->4] Bart DE BIE IV XI} => (P5)  [i1]) probably has a 
corrupted undoMove (my.planner.solver.util.TaskChangeListMove@35e8df37). Or 
maybe there are corrupted score rules.
...


I found out that I did not undo all changes that I made in the move.
After fixing this, I now often get Score corruption as below.
I checked and all changes are preceded with director.beforeVariableChanged(...) 
and followed by director.afterVariableChanged(...);

What could cause this corruption?


java.lang.IllegalStateException: Score corruption: the workingScore

[rules-users] Tree iteration with accumulate: is it possible ?

[mcyrb]

Hello.

I have a tree, with each leaf containing a random value.
The value of each node is the sum of its children value.

I would like to write a rule which looks like this:
when
   nodeValue == 18 (e.g.)
then
   // do something with this node
end

The accumulate conditional element looked adequate for this, so I wrote
something like this
when
   n: Node()
   accumulate( Leaf( parentNode == n, v : value ); nodeValue : sum( v );
nodeValue == 18 )
then
   // do something with n
end

So... the problem is that this works only for nodes where its direct childs
are leafs, and not for upper nodes.
Have you got an idea to solve this ?

Thank you

[rules-users] Drools / Guvnor 6

[Stephen Masters]

Hi folks,

Just wondering whether there's a download available yet for Guvnor v6, or 
whether I need to build from source.

As mentioned previously I'm tinkering with it on WebSphere, and so far (using 
WAS 8.5 Liberty Profile) I am experiencing zero issues. It just works! I'm 
using the Tomcat distribution of Guvnor 5.3. So I'm downloading 5.5 as we 
speak, and I might as well try out 6 while I'm at it. :)

Re: [rules-users] How to integrate Declarative Fact created using Guvnor in Java

[IPatel]

Thank you for your response.

I was able to follow your instruction and  created newInstance of the facts.

Quick question: I have 2 facts defined in Guvnor:
Conditions
Variable: Source (this variable is text/string)
Variable: SourceType (this variable is text/string)

Transcation
Variable: filter (this variable is boolean)

I have 2 rules as follows:
If source =ABC then filter = true

if source =ABC then hasIntegrated = true

In my main method
I created and inserted new instance of each Source as well as Transcation
I set the variables of the source instance so that i can fire above rules.
Source = ABC

Rule 1 fires fine. I get the expected result

However for Rule 2 the value of hasIntegrated is false instead of true. I
run the test in Guvnor and it passes. However in my main method it
fails/give me unexpected result.

Any idea why this is happening???

Yes
Give each entity an extra property: the original value of the planning 
variable property.
For example:

class ShiftAssignment {
Shift shift;
Employee originalEmployee; // Just a normal problem fact
Employee employee; // Planning variable
}

then add a rule which adds a cost for every entity that moved

when
ShiftAssignment( originalEmployee != employee, $employee : employee)
then
// add soft constraint for -(employee.getMoveCost()).

You can make the move cost depend on all sort of factors.

[rules-users] Newbie question. Possibilities for optimizing Employee Schedules

[sanger]

I have an application that requires optimizing an Employee schedule. One of
the criteria is that the schedule must remain as static as possible. In
other words, when conditions change the system must make the minimum number
of adjustments to the schedule to accomodate the new conditions. We would
not want the entire schedule to be shuffled just because one person is off
sick.

Is this a criteria that can be easily handled with Drools Planner?

Re: [rules-users] Fill dependent dropdown lists based on a web decision table

[Michael Anstis]

Did you read the "Advanced" section?

This talks about how you can use an external source of data for
enumerations in Guvnor.

I thought this is what you wanted?

Well, if I understand
  everything correctly, a "Best-solution clone" is needed just
  to remember/represent that state of the solution.
It does not have to do
  anything anymore, therefor some data should not be copied
  and/or initialized upon cloning.
  

True, but that applies for the other cloning events too (at least
the ones initiated by Planner).
In the 6.0 docs, the term "clone" has been replace by the term
"planning clone",
and it's expectations have been explained.
See 4.3.5.6. Cloning a Solution.
 
https://hudson.jboss.org/hudson/view/Drools%20jBPM/job/drools-planner/lastSuccessfulBuild/artifact/drools-planner-docs/target/docbook/publish/en-US/html_single/index.html#d0e2680


  
It might be "not optimal" design that drives me to initializing
stuff upon cloning, but anyway I think there might be more
scenarios where it is useful to know if the solution object is
the working solution or a best solution.
Right?

Michiel

I think a planning solution gets cloned in two

Is this right?
  

Currently this is right IIRC. But mix in multi-threading
for 6.1 or 6.2 and there will be more cases of cloning.

  
If so, how do I know (inside the cloneSolution()
method) if the clone is intended for a best-solution
or a new working-solution?
  

Why would you need to know that? Would it alter your
cloning behavior somehow?

It's probably hackable through BestSolutionRecaller, but
it will give you a hard time when upgrading to 6.0 if
you do hack it there.

Re: [rules-users] Fill dependent dropdown lists based on a web decision table

[peach_wyss]

hy

thanks for your answer.

1) I think you have misunderstood me. I don't want this dropdown list in 
guvnor, we're having our dropdown list on our own form in our application. So 
guvnor should only provide a way to define this dependencies.

2) Where can I define an enum like this 
http://docs.jboss.org/drools/release/5.5.0.Final/drools-guvnor-docs/html_single/index.html#d0e1903
 in the Guvnor-Webclient? When I click on Knowledge Bases > Create New > New 
Enumeration, I can type in something like Fact, Field and Context...which I 
don't understand. Is there a text view for enumerations in guvnor?

Thanks for your help.
