Yes, but I don't think that the cases below apply to my test.
All my facts have a default constructor and they doesn't use the final keyword.
The native data types are used in the LHS only (boolean an integer types) in this way for example:
$allarme : AllarmeMisura(aggregated==false, networkState=="Open")
which i think is allowed (right?).
The base error is a class cast exception it seems:
java.lang.ClassCastException: it.telecomitalia.netbox.AggregatedAlarmShadowProxy
at org.drools.base.it.telecomitalia.netbox.AllarmeTf$getReferencedElement.getValue(Unknown Source)
at org.drools.base.ClassFieldExtractor.getValue(ClassFieldExtractor.java:79)
at org.drools.rule.Declaration.getValue(Declaration.java:156)
at it.telecomitalia.netbox.Rule_Nuovo_Allarme_Misura_No_Allarme_Oggetto_0Predicate0Invoker.evaluate(Rule_Nuovo_Allarme_Misura_No_Allarme_Oggetto_0Predicate0Invoker.java:14)
at org.drools.rule.PredicateConstraint.isAllowedCachedRight(PredicateConstraint.java:190)
AggregatedAlarm is the base class of AllarmeTf, and the LHS of the rule "Nuovo Allarme Misura No Allarme Oggetto" that gives an exception is this:
$allarme : AllarmeMisura(aggregated==false, networkState=="Open")
not AllarmeTf( $tfAllarme :referencedElement ->( $tfAllarme.equals($allarme.getReferencedElement().getReferencedTf())))
To me it seem ok.....
Am I doing something wrong?

The syntax is backwards compatible. However as the release notes mention we no longer autobox primitives, as you can now work directly with them, which will cause issues in old drls that assumed numbers are wrapped. Also pojos must have a default constructor and not use the final keyword at the class and method level - we are actively looking to add more flexability to this case.

Hi all,
the attached example runs ok (slow but ok) on JBoss Rules 3.0.5
Now when I run it with 3.1M1 I have an exception (I pasted it at the end
of the mail).
Is 3.1 M1 backward compatible? Is this a bug? Should I change the code
in some way?
Thanks a lot
