I was looking fro some examples and document which explains on how to use the @Modifies annotations inside Facts(Java class) and it happened for me to see this doc http://docs.jboss.org/drools/release/5.4.0.Beta2/droolsjbpm-introduction-... I tired to implement @PropertySpecific and @Modifies according to the session 3.1.2.1. Fine Grained Property Change Listeners (Property Specific) which is briefly described in the above mentioned link But, when I tried to use @PropertySpecific annotation in my Facts(java class) Eclipse IDE is not able to identify or resolve the package for @PropertySpecific annotation. I am using Drools 5.6.0. Is this @PropertySpecific annotation still supported in Drools, if yes then where is it ? in which package and in which jar ? -- View this message in context: http://drools.46999.n3.nabble.com/Is-PropertySpecific-supported-in-Drools...
