Hello,

I downloaded the JBoss Rules 4.0 Eclipse IDE.  I built a small project with about 120 rules. My test asserts around 500 objects. When I try to add one more rule (regardless of the content of the rule) I get the error below, stating no such method error.  Even if I add the following rule, I still get the error:

rule "new rule"
when
Object()
then
System.out.print("test");
end


What other problems can throw these errors?

Thanks,
Steven
