Hi all, I'm reading Paul Browne's "JBoss Drools Business Rules" and in Ch. 5 we make a BRL in the guided editor. We're using a simple fact model with a single class (Sales) which has (among others) a field "sales", type long. The book uses an earlier version of Guvnor so things look a little different but everything's worked so far, until I use the editor to make a rule that looks like this in "view source": rule "SalesDiscount"   dialect "mvel"   when     mySales : Sales( salesValue : sales >= "100" )   then     mySales.setSales( salesValue-10 );     update( mySales ); end When I try it out, I get this line in the THEN section "1.  Modify value of Sales [mySales]             sales [pencil icon] [remove icon] but neither "sales" nor the pencil icon is clickable, so I can't enter what it should change to. When click view source using what I could do I get: rule "SalesDiscount"   dialect "mvel"   when     mySales : Sales( salesValue : sales >= "100" )   then     mySales.setSales( );     mySales.setWait( );     update( mySales ); end [I added the "wait" because the modify field dropdown has this as an option but it's not in the Java class and I'm not sure where it came from.] Can anyone shed light on this behavior? I'm using the latest version of Firefox, compiling with GWT/building my own EAR (though I haven't done any code changes) using RAD 7.5.5.1 (based on Eclipse 3.4), and am running Guvnor on WebSphere.
