Re: [rules-dev] [rules-users] No eval with backward chaining?
by Wolfgang Laun
Below is a self-contained DRL file where Drools crashes during evaluation
at runtime, even though it compiles and appears to be correct.
package pythagoras;
rule "kickoff"
salience 100
when
then
for( Integer i: new Integer[]{3,4,5,12,13 } ){
insert( i );
}
end
rule "find triple forward"
when
Integer( $a: intValue )
Integer( $b: intValue > $a )
Integer( $c: intValue > $b )
eval( $a*$a + $b*$b == $c*$c )
then
System.out.println( "fwd: " + $a + " " + $b + " " + $c );
end
query isTriple( Integer $a, Integer $b, Integer $c )
Integer( intValue == $a )
Integer( intValue == $b && > $a )
Integer( intValue == $c && > $b )
eval( $a*$a + $b*$b == $c*$c )
end
rule "find triple backward"
when
isTriple( $a, $b, $c; )
then
System.out.println( "bwd: " + $a + " " + $b + " " + $c );
end

Re: [rules-dev] release branches for Beta4 -> Release Delayed
by Edson Tirelli
All,
Just to update everyone, the branches are now tested and stable (thanks
Michael).
From now on, only cherry-pick fixes into them if:
1. The fix is required for Beta4
2. You are sure it will not break the build
Phreak is still not enabled, we are working to get it working, and we
have to delay the release a little longer. As soon as we have that fixed
and cherry-picked into the Beta4 branch, we will proceed with the release.
Feel free to continue with your work on master, but do try to not break
it, of course.
Thank you,
Edson

release branches for Beta4
by Michael Biarnes Kiefer
Hi all,
The release branches are created:
drools, guvnor, etc... : 6.0.0.Beta4.x
jbpm : 6.0.0.Beta4.x
uberfire: 0.2.0.Beta4.x (this was branched from the 0.2.x branch not from master)
We will release from these branches, so the masters are not blocked.
All fixes which have to go in Beta4 release have to be cherry picked by the developers.
Best Regards

Why map of DialectRegistry is = 0
by Charles Moulliard
Hi,
When deploying a drools - spring - camel project on karaf, I get an
exception in this class
https://gist.github.com/anonymous/6f502d28811baaf620fa

as the map of the DialectRegistry is equal to 0
What could be the reason of that problem ? Is it because I'm still using
drools-spring ?

6.0.0-Beta3 Download
by Wolfgang Laun
Is it intentional that some sources are missing from the download as
available on http://www.jboss.org/drools/downloads? I downloaded the
zip from the table line
Drools 6.0.0.Beta3 Drools Expert is the rule engine and Drools Fusion
does complex event processing (CEP). 102,3 MB
File ReadMeDrools.txt tells me, without reservation: "The source jars
are in the sources directory."

commit deadline for Beta4: tonight [19.06.2013]
by Michael Biarnes Kiefer
Hi all,
Due to some limitations of time I want to announce the
commit deadline for the Beta4 release for tonight [19.06.2013].
I will do sanity checks and check if everything is releasable and get in contact with you
if something doesn't build properly.
The last commit I've done (upgrade org.jboss.netty 3.20.Final to io.netty 3.6.2.Final) I have reverted.
I will check if everything works fine and if the kie-wb.war is deployable with this re-change.
If everything works fine I will push the "revert" commit, so that we work again with the org.jboss.netty 3.2.0.Final version.
Sorry for the hurry,
Michael

6.0.0 Beta3

package org.kie.api.event.kiebase;
import org.kie.api.KieBase;
public interface BeforeKieBaseUnlockedEvent
extends
KieBaseEvent {
KieBase getKieBase(); // <<<<<<<<<
}
Overriding an inherited method? Looks strange in Javadoc.
