Hello,
first of all, I would like to thank you for suggestions.
I tried loading drl from file and all work fine. The issue append when the
application load from Guvnor5.3.0 the pkg.
In particular the exception (I mentioned above) happens before calling the
method "SituationManager.createAccessControlEvent":
*public* *static* Event *createAccessControlEvent(*ACObservation obs,
String description, *int* threat_level, Geometry location, *int* sensorid) {
Event event = *new* AccessControlEvent(description,
threat_level, (Geometry)location.clone(), sensorid, obs.getLoginfo(),
obs.getErrno(), obs.getPersonelId());
event.addObservation(obs.getServiceIdentification());
*return* event;
}
I opened the source code at line 56 of
org.drools.reteoo.ReteooFactHandleFactory (I'm using Drools 5.3.0 final):
45. *protected* *final* InternalFactHandle newFactHandle(*final* *int* id,
46. *final* Object object,
47. *final* *long* recency,
48. *final*
ObjectTypeConf conf,
49. *final*
InternalWorkingMemory workingMemory,
50. *final*
WorkingMemoryEntryPoint wmEntryPoint) {
51. *if* ( conf != *null* && conf.isEvent() ) {
52. TypeDeclaration type = conf.getTypeDeclaration();
53. *long* timestamp;
56. *if* ( type.getTimestampExtractor() != *null* ) {
57. *if* ( Date.*class*.isAssignableFrom(
type.getTimestampExtractor().getExtractToClass() ) ) {
58. timestamp = ((Date)
type.getTimestampExtractor().getValue( workingMemory,
59.
object )).getTime();
60. } *else* {
it seems that "type" is null.
Regards
Carolina
