[rules-users] ClassCastException caused by generated java code?!

[Krister Saleck]

Hi,

thanks for the new features in 4.0MR3 - now i may get rid
of some of my workarounds :-)

Unfortunately one problem still pops up in MR3:

Some generated code causes a ClassCastException while casting to
a implementation class. Because JBossRules wraps Facts by a generated
class implementing the facts interface, there should only be some
casting to the interface class?!

caused by: java.lang.ClassCastException: de.myToys.CallContextImpl

rule "Buyer neutral"
	when
		$c : CallContext(cause == "checkout", state == "new")
		$order : Order()
		(Quality(value == 1) or Quality(value == 2))
		eval($order.getBuyer().isProspect())
	then
		$c.setState("neutral");
end

If I execute the rule without the "or" term i do not run into
that problem.... bad rule style?

Did anyone have a hint? 

Thanks in advance,
Krister
