Edson - build2589-rev25264-20090214-0603 is the snapshot that I
downloaded and installed. However, I have done a search on the source
and have not been able to locate
MiscTest.testPropertyChangeSupportNewAPI() in the source at all.
Interestingly, the DRL compilation does not crash if I use
@propertyChangeSupport() or @propertyChangeSupport(true) etc. But
otherwise it crashes. It dies in the following code:
public DecisionEngine() {
super();
try {
rulesEngine = new
RulesEngine("GlucoseDroolRules00.drl");
//rulesEngine = new RulesEngine("rules_version1.drl");
//rulesEngine = new RulesEngine();
} catch (RulesEngineException e) {
System.out.println("Error in DecisionEngine
constructor");
e.printStackTrace();
}
}
public RulesEngine(String rulesFile) throws RulesEngineException {
super();
try {
readDRLintoPackage(rulesFile);
addSpreadsheetToPackage();
} catch (Exception e) {
System.out.println(e);
throw new RulesEngineException("Could not load/compile rules file:
" + rulesFile, e);
}
}
java.lang.NullPointerException

If I do put () after the annotation, the DRL file does compile, but I
do NOT get dynamic behavior.
Thanks.

Can you provide the error messages your are getting?
Make sure you use at least build #2589, that include the changes.
https://hudson.jboss.org/hudson/job/drools/2589/artifact/trunk/target/
There is a test case for this on
MiscTest.testPropertyChangeSupportNewAPI().

Using snapshot from yesterday so presume I have the revision. The
following
DRL file dies a horrible death, being unable to be compiled. If I
comment
out the tags then it works. In the rules editor, the word "declare"
is not
highlighted either. I must be misunderstanding something simple.
package glucose.decision.rules
import glucose.decision.object.GlucoseDecision;
import glucose.decision.object.GlucoseDecisionState;
declare GlucoseDecision
@propertyChangeSupport
end
declare GlucoseDecisionState
@propertyChangeSupport
end
