Hi, when I use the BRL editor, I can't edit the source code of the rule,  
that is available in read-only mode, when you or other users fire this  
rules, you don't have this problem ?

RuleAgent(insuranceconfig) INFO (Fri Aug 03 16:05:58 CLT 2007):
Adding package called org.acme.insurance
org.mvel.CompileException: class or class reference not found: Rejection()
at  
org.mvel.optimizers.impl.asm.ASMAccessorOptimizer.optimizeObjectCreation(ASMAccessorOptimizer.java:1771)


Greetings
