Re: [rules-users] problem in rules 4.0.0.11754MR2

Hi, I am using JBoss Rules 4.0.0.11754MR2 in an RAD 7.0 (Eclipse 3.2) environment. Cannot make it work, even examples... Here is a message produces on all rules: The rule called <here goes rule name> is not valid. Check for compile errors reported. Here is a full stack trace: Exception in thread "main" _java.lang.IllegalArgumentException_: The rule called Hello World is not valid. Check for compile errors reported. at org.drools.common.AbstractRuleBase.addRule(_AbstractRuleBase.java:363_) at org.drools.reteoo.ReteooRuleBase.addRule(_ReteooRuleBase.java:263_) at org.drools.common.AbstractRuleBase.addPackage(_AbstractRuleBase.java:293_) at org.drools.examples.HelloWorldExample.readRule(_HelloWorldExample.java:72_) at org.drools.examples.HelloWorldExample.main(_HelloWorldExample.java:21_) After digging it further I found that in Rule class method isValid is being called defiend as followes: *public* *boolean* isValid() { *if* ( *this*.consequence == *null* || !isSemanticallyValid() ) { *return* *false*; } *return* *true*; } The debugger shows that *this*.consequence is null always! So rules are always not valid. Anyone saw this problem? Any idea how to resolve it?
