add process only -> bug ?
by hypnosat7
hi,
I try to add a ruleflow to my rule base :
builder.addRuleFlow(RULE_FLOW);
Package pkg = builder.getPackage();
ruleBase.addPackage(builder.getPackage());
But !!:
java.lang.NullPointerException
at
org.drools.compiler.PackageBuilder.addRuleFlowsToPackage(PackageBuilder.java:469)
at org.drools.compiler.PackageBuilder.getPackage(PackageBuilder.java:449)

Check for overlapping dates
by Brian Enderle
I have a situation where I need to check for overlapping dates in a collection
of previous addresses. I am only performing this check after checking that
the beginDate and endDate are not null.
Currently I am using an eval to perform an outside method. Does anyone know
if and how I could perform this same check using Drools.
Curently my rules look something like this
gloabl java.lang.Boolean dateErrorExists; // starts off as false
global ValidationUtils utils;
rule "beginDate must exist"
when
Address ( beginDate != null )
then
dateMissing = true;
<display error>
end
rule "endDate must exist"
when
Address ( endDate != null )
then
dateMissing = true;
<display error>
end
rule "Previous Address dates cannot overlap"
salience -10
when
eval (dateMissing)
eval (utils.doAddressDatesOverlap())
then
<display error>
end
Our system simply runs thru the data checking the rules (no facts are changed)
so the dateMissing global is reset to false everytime we perform our
validation.
The downside to this is I am having to re-get the data from the DB within the
doAddressDatesOverlap() function. This function orders the Address objects by
their startDates and then compares the endDate of one with the startDate of
the next and returns false if they overlap.
If anyone knows of a cleaner, simpler or better way to perform this check
within Drools I would appreciate the input.
Thanks in advance,

problem with threads
by Raffaele Viola
Hi all,
I have a HashTable dawned by a thread T1, another thread T2 take this
HashTable and give it to the working memory as assertion.
what happens if T2 and JRools try to access to the HashTable?
Can I consider the working memory as a thread and use a method
synchronization to solve the concurrent access problem?
Thanks

Decision table actions
by Hehl, Thomas
I have at least figured out what was going on with my decision table.
I kept comparing what I was doing with the policy pricing example included
with drools and trying to figure out what I was doing different. Because of
the syntax of the rules I was getting back, it occurred to me that the issue
might be that I was never referencing my recipient object as part of the
condition.
I added a property to my BooleanAnswer object so it now looks like:
public class BooleanAnswer {
private boolean answer;
private int index = 2;
/**
* no-arg constructor
*/
public BooleanAnswer(){
}
/**
* create your own default answer
* @param answer the answer to set
*/
public BooleanAnswer(boolean answer){
setAnswer(answer);
}
/**
* @return the answer
*/
public boolean isTrue() {
return answer;
}
/**
* @param answer the answer to set
*/
public void setAnswer(boolean answer) {
this.answer = answer;
}
/**
* @return the index
*/
public int getIndex() {
return index;
}
/**
* @param index the index to set
*/
public void setIndex(int index) {
this.index = index;
}
I then modified my Decision table so it looks like:
CONDITION
ACTION
answer: BooleanAnswer
index
answer.setAnswer($param);
index
Allowed
2
TRUE
TRUE
This built the proper rule and works fine.
It appears that drools is not set up to store values in an object that was
not referenced in the condition. Is this true? If so, it seems this should
be a request for future enhancement.
If not, then how do I do this without referencing my recipient object in the
condition.
Thanks!

FW: [rules-users] FW: Decision Tables
by Hehl, Thomas
The reason that I feel that this is AT LEAST a documentation bug is that I
believe that I've coded my answer exactly as the ExamplePricingPolicy is
coded, but it produces invalid rules.
Can someone please confirm that I'm doing this right or tell me what I'm
doing wrong? Doesn't anyone on this list use decision tables and have some
counsel?
Thanks.

This isn't bug, you aren't using drools correctly. Only valid java can be
used in an Action. anAnswer:BooleanAnswer is not valid java and shows up in
your generated code:
anAnswer: BooleanAnswer.anAnswer.setAnswer(true);;

I'm starting to think this is a bug in decision tables for 4.0 GA.
The following entry:
ACTION
anAnswer: BooleanAnswer
anAnswer.setAnswer($param);
Allowed
TRUE
TRUE
Generates this rule:
rule "postponePart_10"
when
PoolInfo(courtLocation == "101", statusCode >= 0, statusCode <=
2, numberFta < 1, numberOfDeferralsPosted < 2, daysBeforeSummons>= 1,
daysBeforeSummons<= 1)
then
anAnswer: BooleanAnswer.anAnswer.setAnswer(true);;
end
This doesn't seem right at all. What I'm trying to do is to call the
setAnswer method on the object I passed in with:
StatelessSession session =
participantRuleBase.newStatelessSession();
//now create some test data
PoolInfo pool = part.getActivePool();
BooleanAnswer answer = new BooleanAnswer();
Object[] rules = new Object[]{pool, answer};
session.execute(rules);
return answer.isTrue();
Advice?
Thanks.

Subject: Decision Tables
I'm having trouble figuring out the ACTION section of a decision table.
Everything else appears to be working.
My rules result in a simple True/False condition. To do this in a decision
table, I've created a class called BooleanAnswer that looks like:
public class BooleanAnswer {
private boolean answer;
/**
* no-arg constructor
*/
public BooleanAnswer(){
}
/**
* create your own default answer
* @param answer the answer to set
*/
public BooleanAnswer(boolean answer){
setAnswer(answer);
}
/**
* @return the answer
*/
public boolean isTrue() {
return answer;
}
/**
* @param answer the answer to set
*/
public void setAnswer(boolean answer) {
this.answer = answer;
}
}
Then I create a decision table with the following ACTION in it:
ACTION
answer: BooleanAnswer
answer.setAnswer($param);
Allowed
TRUE
This generates the following errors:

The problem appears to be that the rule being generated is just flat wrong.
I'm starting to think this is a bug in decision tables for 4.0 GA.
The following entry:
ACTION
anAnswer: BooleanAnswer
anAnswer.setAnswer($param);
Allowed
TRUE
TRUE
Generates this rule:
rule "postponePart_10"
when
PoolInfo(courtLocation == "101", statusCode >= 0, statusCode <=
2, numberFta < 1, numberOfDeferralsPosted < 2, daysBeforeSummons>= 1,
daysBeforeSummons<= 1)
then
anAnswer: BooleanAnswer.anAnswer.setAnswer(true);;
end
This doesn't seem right at all. What I'm trying to do is to call the
setAnswer method on the object I passed in with:
StatelessSession session =
participantRuleBase.newStatelessSession();
//now create some test data
PoolInfo pool = part.getActivePool();
BooleanAnswer answer = new BooleanAnswer();
Object[] rules = new Object[]{pool, answer};
session.execute(rules);
return answer.isTrue();
Advice?
Thanks.

I'm having trouble figuring out the ACTION section of a decision table.
Everything else appears to be working.
My rules result in a simple True/False condition. To do this in a decision
table, I've created a class called BooleanAnswer that looks like:
public class BooleanAnswer {
private boolean answer;
/**
* no-arg constructor
*/
public BooleanAnswer(){
}
/**
* create your own default answer
* @param answer the answer to set
*/
public BooleanAnswer(boolean answer){
setAnswer(answer);
}
/**
* @return the answer
*/
public boolean isTrue() {
return answer;
}
/**
* @param answer the answer to set
*/
public void setAnswer(boolean answer) {
this.answer = answer;
}
}
Then I create a decision table with the following ACTION in it:
ACTION
answer: BooleanAnswer
answer.setAnswer($param);
Allowed
TRUE
This generates the following errors:
