Hello,
I´m working with the last successful build(22-may-2010) of drools5.1. I
get the error below, when I try to insert a class instance in the
working memory. This only happens when conditional part of a rule is
satisfied.
I´ve read in previous mails of this mailing list something about this
error and it seems that is related with the call of static method.
http://lists.jboss.org/pipermail/rules-users/2008-January/004485.html
I have a rule that would be activated after the insertion of the
instance. The rule is the following:
rule "ruleA"
ruleflow-group "BlockStageOrder1Round1"
when
State(SizeX : width, SizeY : height)
support : ClassifierPropositionSupport(fDescriptor : frameDescriptor,
fatherClass == "blue", x >= 0 && < (SizeX/4), y >= 0 &&
< (SizeY/4))
then
ProposeClassifiers.SetClassifier(drools, fDescriptor,"sky");
end
Can you help me solving this?
Thank you in advance,
Kevin.
