[rules-users] Trivial rule with condition in RHS won't compile, help please

The following rule: rule "test" dialect "mvel" when eval(true) then if (true) { System.out.println("***") } end Fails with: java.lang.RuntimeException: Unable to build expression for 'consequence': was expecting type: java.lang.Object; but found type: void ' if (true) { System.out.println("***") } true ' : [Rule name='test'] I can't for the live of me figure out what mvel is bitching about. Note that the following does compile: rule "test" dialect "mvel" when eval(true) then // if (true) { System.out.println("***") // } end -- View this message in context: http://n3.nabble.com/Trivial-rule-with-condition-in-RHS-won-t-compile-hel...
