[rules-users] Apply role to whole class hierarchy

[Vincent LEGENDRE]

I had the same strange problem some time ago (last winter), but I never managed to reproduce a small sample.... 
I checked, and my problematic class hierarchy also lived in different packages (and never tried that that for my smaller samples) .

After some debugging I was able to shed some light on what causes the 
problem, even if I don't fully understand it. The problem is produced by the 
event base class, which is declared with @role(event), i.e. (VSCPEvent) 
living in a different package than the ButtonEvent. If I move then into the 
same package, everything works just fine. 
The two package instances are merged in PackageBuilder.mergePackage(...), 
but the RuleBuilder still seems to operate on two separate instances, one 
with the declarations and Package.isEvent(...) returning true for the 
ButtonEvent and the other without them. Unfortunately, as I know too little 
about the workings of the various builders, I can't provide you with a 
ready-made idea of how to fix the problem. 

See https://issues.jboss.org/browse/JBRULES-3587 

Thanks 
Joerg
