----------------------------------



>From reading the Drools blog, it seems that 6.0 will be/is a major rewrite of Drools that will not be backwards compatible. Any chance this can be fixed on the 5.5 code base?

> We have a Java class that uses java.sql.Timestamp to record time values. In Drools 5.0.1, we were able to use the @timestamp annotation as follows:
> {code}
> declare StateEvent
> 	@role( event )
> 	@timestamp( startTime )
> 	@duration( duration )
> end
> {code}
> StateEvent contains the following:
> {code}
> import java.sql.Timestamp;
> ...
>     private Timestamp startTime;
>     private Long duration;
>     public Timestamp getStartTime() {
>         return startTime;
>     }
>     public void setStartTime(Timestamp st) {
>         startTime = st;
>     }
>     public Long getDuration() {
>         return duration;
>     }
>     public void setDuration(Long d) {
>         duration = d;
>     }
> ....
> {code}
> We load the rules from a .drl file as follows:
> {code}
> KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
> kbuilder.add(ResourceFactory.newClassPathResource("path-to-file", ResourceType.DRL);
> {code}
> In 5.4.0, this no longer works and we get the error message:
> {code}
> Annotated type StateEvent - undefined property in @annotation timestamp: java.sql.Timestamp.value();
> {code}
> Also tested with 5.5.0.Final and 5.5.0.CR1
