[rules-users] is property type casting into variable supported ?

I filled bug https://issues.jboss.org/browse/DROOLS-136 because the way I tried to use # symbol hangs Drools. I would like to ask the group if following type casting is supported in Drools in Java or in MVEL: rule "calculate totalPrice per item" salience -10 no-loop dialect "java" when $q:Message(id=="item", answered==true, $v:value#DataItemPrice) then System.out.println("this works: " + ((DataItemPrice)$v).getName()); // will this also work ? at least in MVEL System.out.println("will this work ?: " + $v.getName()); end thank you, Martin Minka
