[rules-users] Splitted Sentences in DSL...
Hi guys,
As u can notice in the
http://labs.jboss.com/file-access/default/members/drools/images//templatebaseddsl2.png
DSL
pop-up Menu,
we have got the sentence Escalate the ticket splitted into 3 different
sub-sentences:
1. Escalate
2. Escalate the
3. Escalate the ticket
When I open *org.drools.examples.TroubleTicketWithDSL.dslr* from the *
drools-examples/drools-examples-drl/src/main/rules/org/drools/examples*
directory and i push CTRL+SPACE in Eclipse Europa 3.3, then the pop-up
menu I get back shows just one of the sentences above.
It just shows: Escalate the ticket.
I expected to see all the above sentences, as I saw in the JBoss Drools
Features page (
http://labs.jboss.com/file-access/default/members/drools/images//templatebaseddsl2.png
).
So Why Do I get a different menu with just one sentence?
Is the .dsl file referred from the .drls in the feature page different
from the following one?
*[condition][]There is a customer ticket with status of {status}=customer
: Customer( ) ticket : Ticket( customer == customer, status == {status}
)
[condition][]There is a {subscription} customer with a ticket status of
{status}=customer : Customer(subscription == {subscription}) ticket :
Ticket( customer == customer, status == {status})
[consequence][]Log {message}=System.out.println({message} );
[consequence][]Escalate the ticket=ticket.setStatus(Escalate);
update(ticket);
[consequence][]Send escalation email=sendEscalationEmail( customer, ticket
);*
*One more question.*
I have got no idea on the Object column which accours in the DSL Editor.
We have got Language Expression, , *Object* and Scope.
What does *Object* stand for?
Thank You for any help you can give me.

Re: [rules-users] Strange property access behavior resulting in NullPointerException
Henry, If you look at the stack trace, the NPE happens inside your own class method: at org.activequant.core.domainmodel.TimeSeries.getInstrumentSpecification(Unknown Source) So, you need to look at what that method is doing to know why it is raising the NPE. []s Edson 2008/1/15, Henry Canterburry [EMAIL PROTECTED]: I am using Drools 4.0.3. I have a rule that I believe should work but causes a NullPointerException at runtime. The rule phrased this way causes a NullPointerException: rule Create Order Limit when CandleSeries( $instrument : instrumentSpecification ) then insert(new OrderConstraint( $instrument )); end While the same rule phased like this works fine: rule Create Order Limit when $candle : CandleSeries( ) then insert(new OrderConstraint( $candle.getInstrumentSpecification() )); end Is this right? I was looking at rule example 10.27 in the Drools guide and it's written exactly like rule #1 is.

Re: [rules-users] Error creating shadow fact for object: [] when inserting Collection into working memory
Henry,
This is tricky. Can you please open a JIRA for it? I will take a look as
soon as I can on how to fix that.
Meanwhile, the workaround is: instead of inheriting from a collection
class, can you wrap it instead?
public class NamedCollectionT {
private String name;
private LinkedListT list;
// constructor, getters, setters
}
This change will make it work for you.

I am having the same problem as described in this post:
http://www.nabble.com/The-effect-of-not-using-shadow-facts-tp11652637p11708600.html
The problem is, there really was no solution mentioned. Here is my
collections class that I am asserting into working memory:
public class NamedCollectionT extends LinkedListT{
public NamedCollection(String name){
super();
this.name = name;
}
public String getName(){
return name;
}
/**

private static final long serialVersionUID = -457439174592908333L;
private String name;
@Override
public int hashCode() {
final int prime = 31;
int result = super.hashCode();
result = prime * result + ((name == null) ? 0 : name.hashCode());
return result;
}
@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (!super.equals(obj))
return false;
if (getClass() != obj.getClass())

if (name == null) {

return false;
} else if (!name.equals(other.name))

Re: [rules-users] Prefix 'and' and infix 'and' not interchangeable?
Actually, I just understood the problem. The not CE requires () when used with anything that is not a simple pattern. So the following are valid constructions: not A() not( A() and B() ) Now, if you want to use a prefixed and/or, it also requires a (). So the following is a valid construction: not( (and A() B() ) ) So, the proposed construction is not valid for current grammar, because it is missing one pair of (): not( and A() B() ) // WRONG Now, I do think it would be desirable for us to support the above construction, so if you open a ticket for that I will look into enabling it.

[rules-users] shadow copy lacks a property value of the original fact
I was just debugging my rules and monitored my working memory and
variables, trying to figure out why a certain Pattern match was not
firing, and noticed that a property value for a fact I inserted earlier
via the RHS does not seem to be inserted into working memory along with
the object. The fact's delegate (?) has the property value, but the fact
(as displayed in the variables tab) has a null value for the property.
Here is the rule that inserts the fact into memory:
rule Explode Globals
when
$request : DecisionRequest( )
$input : Object() from $request.getRequestObjects().values()
then
insert ( $input );
end
Just before the insert executes, $input looks like this in the variables
tab:
$input - NamedCollectionT (id=61)
list - LinkedListE (id=62)
name - constraints
After the insert however, when the engine checks the name value in my
java class, the same fact now looks like this in the variables tab:
this - NamedCollectionShadowProxy (id=83)
delegate - NamedCollectionT (id=61)
list - LinkedListE (id=62)
name - constraints
list - LinkedListE (id=87)
name - null ??
So, when I next have a rule that looks like this:
rule Assemble Constraints
when
$const : OrderConstraint()
$coll : NamedCollection( name == constraints )
then
$coll.add($const);
update($coll);
end
Here is the java class:
public class NamedCollectionT implements CollectionT{
private static final long serialVersionUID = -457439174592908333L;
private CollectionT list = new LinkedListT();
private String name;
public NamedCollection(){
}
public NamedCollection(String name){
this.name = name;
}
...more methods...
public String getName(){
return this.name;
}
public void setName(String name){
this.name = name;
}
}
The pattern does not match since the value for name is null! When I
place a breakpoint in my java code during drools debugging, the name
value will return null each time. I also have another rule that creates
a new OrderConstraint, so all conditions for the last rule to fire
exist...other than the name property being null although it is set in
the delegate. I do not have any other rules that modify the
NamedCollection.
What am I doing wrong? Is this again related to having a class implement
a collection?

[rules-users] Can From reason over primitive arrays?
I am trying to pattern match on a primitive array such as String[] or SomeObject[]. The documentation only mentions collections in the section about From. Would a pattern match syntax such as... rule My rule when $source : SourceObject() $myObject : MyObject() from $source.returnsAnArrayProperty then ..be correct? If not, how can capture and loop over every object in an array (not Collection)? I have tried the above and I get a ClassCastException.

[rules-users] Basic Question about Errors
Hi,
it's a basic question but since half a year i am not sure how to read the error
[53,61]: unknown:53:61 Unexpected token '('[53,73]: unknown:53:73
mismatched token: [EMAIL PROTECTED],2278:2278=')',12,53:73]; expecting type
THEN[65,61]:
which line/position is indicated in the corresponding rule file. Every
time, when i think now i got it the next error shows me i'm not right.
Cheers
Markus
